Open data portals help municipalities to offer structured and transparent access to the data they generate in the exercise of their functions and in the provision of the services they are responsible for, while also fostering the creation of applications, services and solutions that generate value for citizens, businesses and public administrations themselves. 

The report aims to provide a practical guide for municipal administrations to design, develop and maintain effective open data portals, integrating them into the overall smart city strategy. The document is structured in several sections ranging from strategic planning to technical and operational recommendations necessary for the creation and maintenance of open data portals. Some of the main keys are: 

Fundamental principles 

The report highlights the importance of integrating open data portals into municipal strategic plans, aligning portal objectives with local priorities and citizens' expectations. It also recommends drawing up a Plan of measures for the promotion of openness and re-use of data (RISP Plan in Spanish acronyms), including governance models, clear licences, an open data agenda and actions to stimulate re-use of data. Finally, it emphasises the need for trained staff in strategic, technical and functional areas, capable of managing, maintaining and promoting the reuse of open data. 

General requirements 

In terms of general requirements to ensure the success of the portal, the importance of offering quality data, consistent and updated in open formats such as CSV and JSON, but also in XLS, favouring interoperability with national and international platforms through open standards such as DCAT-AP, and guaranteeing effective accessibility of the portal through an intuitive and inclusive design, adapted to different devices. It also points out the obligation to strictly comply with privacy and data protection regulations, especially the General Data Protection Regulation (GDPR). 

To promote re-use, the report advises fostering dynamic ecosystems through community events such as hackathons and workshops, highlighting successful examples of practical application of open data. Furthermore, it insists on the need to provide useful tools such as APIs for dynamic queries, interactive data visualisations and full documentation, as well as to implement sustainable funding and maintenance mechanisms. 

Technical and functional guidelines 

Regarding technical and functional guidelines, the document details the importance of building a robust and scalable technical infrastructure based on cloud technologies, using diverse storage systems such as relational databases, NoSQL and specific solutions for time series or geospatial data. It also highlights the importance of integrating advanced automation tools to ensure consistent data quality and recommends specific solutions to manage real-time data from the Internet of Things (IoT). 

In relation to the usability and structure of the portal, the importance of a user-centred design is emphasised, with clear navigation and a powerful search engine to facilitate quick access to data. Furthermore, it stresses the importance of complying with international accessibility standards and providing tools that simplify interaction with data, including clear graphical displays and efficient technical support mechanisms. 

The report also highlights the key role of APIs as fundamental tools to facilitate automated and dynamic access to portal data, offering granular queries, clear documentation, robust security mechanisms and reusable standard formats. It also suggests a variety of tools and technical frameworks to implement these APIs efficiently. 

Another critical aspect highlighted in the document is the identification and prioritisation of datasets for publication, as the progressive planning of data openness allows adjusting technical and organisational processes in an agile way, starting with the data of greatest strategic relevance and citizen demand. 

Finally, the guide recommends establishing a system of metrics and indicators according to the UNE 178301:2015 standard to assess the degree of maturity and the real impact of open data portals. These metrics span strategic, legal, organisational, technical, economic and social domains, providing a holistic approach to measure both the effectiveness of data publication and its tangible impact on society and the local economy. 

Conclusions 

In conclusion, the report provides a strategic, technical and practical framework that serves as a reference for the deployment of municipal open data portals for cities to maximise their potential as drivers of economic and social development. In addition, the integration of artificial intelligence at various points in open data portal projects represents a strategic opportunity to expand their capabilities and generate a greater impact on citizens.

The value of open satellite data in Europe

Satellites have become essential tools for understanding the planet and managing resources efficiently. The European Union (EU) has developed an advanced space infrastructure with the aim of providing real-time data on the environment, navigation and meteorology.

This satellite network is driven by four key programmes:.

• Copernicus: Earth observation, environmental monitoring and climate change.
• Galileo: high-precision satellite navigation, alternative to GPS.
• EGNOS: improved positioning accuracy, key to aviation and navigation.
• Meteosat: padvanced meteorological prediction and atmospheric monitoring.

Through these programmes, Europe not only ensures its technological independence, but also obtains data that is made available to citizens to drive strategic applications in agriculture, security, disaster management and urban planning.

In this article we will explore each programme, its satellites and their impact on society, including Spain''s role in each of them.

Copernicus: Europe''s Earth observation network

Copernicus is the EU Earth observation programme, managed by the European Commission with the technical support of the European Space Agency (ESA) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT).. It aims to provide free and open data about the planet to monitor climate change, manage natural resources and respond to emergencies.

The programme is structured into three main components:

1. Space component: consists of a series of satellites called Sentinel, developed specifically for the needs of Copernicus. These satellites provide high quality data for various applications, such as land, sea and atmospheric monitoring.
2. Component in situ: includes data collected through ground, air and sea stations. These data are essential to calibrate and validate the information obtained by the satellites, ensuring its accuracy and reliability.
3. Operational Services: offers six thematic services that transform collected data into useful information for users:
   • Atmospheric monitoring
   • Marine monitoring
   • Terrestrial monitoring
   • Climate change
   • Emergency management
   • Safety

These services provide information in areas such as air quality, ocean status, land use, climate trends, disaster response and security, supporting informed decision-making in Europe.

Spain has played a key role in the manufacture of components for the Sentinel satellites. Spanish companies have developed critical structures and sensors, and have contributed to the development of data processing software.  Spain is also leading projects such as the Atlantic Constellation, which will develop small satellites for climate and oceanic monitoring.

Galileo: the european GPS

Galileo is the global navigation satellite system developed by the European Union, managed by the European Space Agency (ESA) and operated by the European Union Space Programme Agency (EUSPA). It aims to provide a reliable and highly accurate global positioning service, independent of other systems such as the US GPS, China''s Beidou or Russia''s GLONASS. Galileo is designed for civilian use and offers free and paid services for various sectors, including transport, telecommunications, energy and finance.

Spain has played a leading role in the Galileo programme. The European GNSS Service Centre (GSC), located in Torrejón de Ardoz, Madrid, acts as the main contact point for users of the Galileo system. In addition, Spanish industry has contributed to the development and manufacture of components for satellites and ground infrastructure, strengthening Spain''s position in the European aerospace sector.

EGNOS: improving the accuracy of GPS and Galileo

 The European Geostationary Navigation Overlay Service (EGNOS) is the European satellite-based augmentation system (Satellite Based Augmentation System or SBAS) designed to improve the accuracy and reliability of global navigation satellite systems ( Global Navigation Satellite System, GNSS), such as GPS and, in the future, Galileo. EGNOS provides corrections and integrity data that allow users in Europe to determine their position with an accuracy of up to 1.5 metres, making it suitable for safety-critical applications such as aviation and maritime navigation.

Spain has played a leading role in the development and operation of EGNOS. Through ENAIRE, Spain hosts five RIMS Reference Stations located in Santiago, Palma, Malaga, Gran Canaria and La Palma. In addition, the Madrid Air Traffic Control Centre, located in Torrejón de Ardoz, hosts one of the EGNOS Mission Control Centres (MCC), operated by ENAIRE. The Spanish space industry has contributed significantly to the development of the system, with companies participating in studies for the next generation of EGNOS.

Meteosat: high precision weather forecasting

The Meteosat programme consists of a series of geostationary meteorological satellites initially developed by the European Space Agency (ESA) and currently operated by the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT). These satellites are positioned in geostationary orbit above the Earth''s equator, allowing continuous monitoring of weather conditions over Europe, Africa and the Atlantic Ocean. Its main function is to provide images and data to facilitate weather prediction and climate monitoring.

Spain has been an active participant in the Meteosat programme since its inception. Through the Agencia Estatal de Meteorología (AEMET), Spain contributes financially to EUMETSAT and participates in the programme''s decision-making and operations. In addition, the Spanish space industry has played a key role in the development of the Meteosat satellites. Spanish companies have been responsible for the design and supply of critical components for third-generation satellites, including scanning and calibration mechanisms.

Access to the data of each programme

Each programme has different conditions and distribution platforms in terms of access to data:

• Copernicus: provides free and open data through various platforms.  Users can access satellite imagery and products through the Copernicus Data Space Ecosystem, which offers search, download and processing tools. Data can also be obtained through APIs for integration into automated systems.
• Galileo: its open service (Open Service - OS) allows free use of the navigation signals for any user with a compatible receiver, free of charge. However, direct access to raw satellite data is not provided. For information on services and documentation, access is via the European GNSS Services Centre (GSC):
  • Galileo Portal.
  • Registration for access to the High Accuracy Service (HAS) (registration required).
• EGNOS: This system improves navigation accuracy with GNSS correction signals.  Data on service availability and status can be found on the EGNOS User Support platform..
• Meteosat: Meteosat satellite data are available through the EUMETSAT platform. There are different levels of access, including some free data and some subject to registration or payment.  For imagery and meteorological products you can access the EUMETSAT Data Centre..

In terms of open access, Copernicus is the only programme that offers open and unrestricted data. In contrast, Galileo and EGNOS provide free services, but not access to raw satellite data, while Meteosat requires registration and in some cases payment for access to specific data.

Conclusions

The Copernicus, Galileo, EGNOS and Meteosat programmes not only reinforce Europe''s space sovereignty, but also ensure access to strategic data essential for the management of the planet. Through them, Europe can monitor climate change, optimise global navigation, improve the accuracy of its positioning systems and strengthen its weather predictioncapabilities, ensuring more effective responses to environmental crises and emergencies.

Spain plays a fundamental role in this space infrastructure, not only with its aerospace industry, but also with its control centres and reference stations, consolidating itself as a key player in the development and operation of these systems.

Satellite imagery and data have evolved from scientific tools to become essential resources for security, environmental management and sustainable growth. In a world increasingly dependent on real-time information, access to this data is critical for climate resilience, spatial planning, sustainable agriculture and ecosystem protection.

The future of Earth observation and satellite navigation is constantly evolving, and Europe, with its advanced space programmes, is positioning itself as a leader in the exploration, analysis and management of the planet from space.

Access to this data allows researchers, businesses and governments to make more informed and effective decisions. With these systems, Europe and Spain guarantee their technological independence and strengthen their leadership in the space sector.

Although local governments are the closest actors to citizens, they often face limitations in terms of resources and capacities to implement open data effectively. The diputations, as intermediate institutions between central government and municipalities, play a key role in coordinating, supporting and facilitating open data at the local level.

In this article, we will explore the work of the Diputaciones in this area, showing some examples.

Why is it important for local authorities to commit to open data?

Local open data is of great importance to citizens because of its high granularity. These data provide information on specific settings, which gives a detailed picture of the situation of citizens in that area and shows disparities between municipalities.

This offers multiple advantages. On the one hand, public administrationscan develop better policies and manage resources more efficiently. On the other hand, businesses, researchers and entrepreneurshave the opportunity to develop new, more customised solutions based on the needs of each location. It also improves transparency and accountability, fostering trust in local institutions, and facilitates citizen participationby giving residents access to key data about their municipalities, which can contribute to more active and informed decision-making.

Challenges for local authorities in opening up their data

Despite the advantages, local authorities face a number of challenges in trying to make their data available to citizens, many of which are related to resource constraints and technical capacity:

• Lack of technical and human resources: Many municipalities, especially small and medium-sized ones, do not have the trained staff and resources to manage and publish open data. Lack of IT and data management expertise can hinder the implementation of open data initiatives.
• Inadequate infrastructure: Open data requires adequate technological infrastructure, such as platforms and storage systems to host data in an accessible and secure way.
• Awareness and resistance to change: In some municipalities, both policy makers and public employees may not fully understand the benefits of open data, leading to resistance to change.
• Data quality and standardisation issues: Municipal data are often scattered across different systems and formats, which can make standardisation and validation difficult. Ensuring that data is correct, up to date and in reusable formats is a major technical challenge.
• Cost of implementing, maintaining and updating data: Opening up data involves not only having the right infrastructure and staff, but also investing in platforms, software and other tools needed to make the information accessible to the public, which can be a barrier for municipalities with tight budgets. Moreover, once data is available to the public, it is necessary to keep it up to date and ensure that it remains relevant, which is a constant effort.

How can county councils help local authorities to overcome these challenges?

The Diputaciones are supra-municipal entities whose functions include legal, economic and technical assistance and cooperation to the municipalities in their province, especially those of smaller size or fewer resources. Among other things, they offer support in technological and managerial matters, for example in administrative tasks, the provision of public services or economic development.

In the context of open data, local councils can act as "facilitators" of open data at local level, through different actions:

1. Technical advice and training

The Diputaciones offer training to municipalities so that municipal employees can learn how to manage and open data. This is something that the Diputación de Salamanca, for example, has done with this course, whose objectives included raising participants' awareness of the importance of open data as a means to enhance citizen participation, helping them to understand technical issues in order to boost the degree of openness of institutions.

The Diputación de Castellón, for its part, provides support to small municipalities in opening their data, offering support materials related to open data. Another example is the Provincial Council of Albacete, which provides technical assistance, monitoring and support to its 87 municipalities through the Provincial Sustainability Observatory of Albacete (OPSA), an entity in collaboration with the University of Castilla-La Mancha. To this end, it offers sustainability reports (with 25 indicators), monitors its localization plans and emission studies, offers training and guides related to the sustainability of its municipalities related to open data, etc. 

2. Technological infrastructure

Some councils provide digital platforms and tools for municipalities to upload and share data in a simple way. This includes hosting open data portals or analysis and visualisation tools.

This is the case of the Diputación de Bizkaia, whose scope affects the foral public sector (Foral Entities) and the Local Entities of Bizkaia. Through the BiscayTIK foundation, municipalities can join the Open Data Bizkaia portal so that their data can appear on this portal. In addition, a customised view is generated that can be embedded in the municipality's own website, in case they want to have their own open data portal.

Another example is the Diputación de Córdoba. Its provincial strategy consists of unifying efforts and making a common platform for all municipalities, through automated processes of extraction and processing of structured information for publication, without the need for manual dedication on the part of staff. Through the Enlaza project, the platform receives and monitors information obtained both from citizens and from the sensors and systems of the multiple municipal services, and then carries out a cross analysis of the data. With this service, all the town councils in the province of Cordoba can have a homogeneous catalogue of open data with automated loading, which in turn is federated with datos.gob.es, saving this procedure for smaller administrations.

The Diputación de Albacete, for its part, has a platform with an open data exhibition of the panel of local indicators of the province (48 sub-indicators with a historical series of +15 years). The standardization of open data facilitates municipal and provincial analysis, allowing the comparison of municipalities with graphical and georeferenced output. Includes download space with user registration.

Thanks to these actions double efforts and duplication of uploading of information on various platforms are avoided. In addition, the standardisation of open data facilitates regional analysis and comparison between municipalities, generating new opportunities for innovation and improvement in the quality of life of citizens.

3. Grants or funding

Sometimes, the local councils allocate financial resources so that small municipalities can implement open data projects. An example of this is the Diputación de Valencia, whose functions include fostering and developing the right of access to information, as well as promoting the re-use of public data. To this end, in 2024, it launched a series of aids.

In this line the Diputación de Albacete has an annual aid or call for municipalities to implement their Agendas 2030 or projects related to sustainability and included in their plans. For example, in February 2025 the call was published with a budget of € 325,000.

4. Awareness-raising and reuse promotion actions

Another area where county councils can help is the promotion of favourable frameworks for data re-use. The Diputación de Castellón, for example, maintains a close relationship with civil society organisations and universities to meet their data demands. With the collaboration of the Diputación de Barcelona and the Government of Aragón, organised in 2024 the III National Open Data Meeting, where the importance of open data as a resource for understanding and achieving interesting and sustainable tourism was disseminated.

For its part, the Diputación de Bizkaia is launching competitions such as the Open Data & Artificial Intelligence Challenge, aimed at identifying initiatives that combine the reuse of data available on the Open Data Bizkaia portal with the use of this disruptive technology in various sectors.

In conclusion, the collaboration between councils and municipalities makes it possible to generate greater cohesion in the opening of data throughout the territory, ensuring that all municipalities, regardless of their size or resources, have access to the necessary tools and knowledge. However, local councils also have their technical and resource limitations, so this is an area where further progress needs to be made, with a focus on raising awareness of the benefits of open data and collaboration between institutions.

The increasing adoption of artificial intelligence (AI) systems in critical areas such as public administration, financial services or healthcare has brought the need for algorithmic transparency to the forefront. The complexity of AI models used to make decisions such as granting credit or making a medical diagnosis, especially when it comes to deep learning algorithms, often gives rise to what is commonly referred to as the "black box" problem, i.e. the difficulty of interpreting and understanding how and why an AI model arrives at a certain conclusion. The LLLMs or SLMs that we use so much lately are a clear example of a black box system where not even the developers themselves are able to foresee their behaviour.

In regulated sectors, such as finance or healthcare, AI-based decisions can significantly affect people's lives and therefore it is not acceptable to raise doubts about possible bias or attribution of responsibility. As a result, governments have begun to develop regulatory frameworks such as the Artificial Intelligence Regulation that require greater explainability and oversight in the use of these systems with the additional aim of generating confidence in the advances of the digital economy.

Explainable artificial intelligence (XAI) is the discipline that has emerged in response to this challenge, proposing methods to make the decisions of AI models understandable. As in other areas related to artificial intelligence, such as LLLM training, open data is an important ally of explainable artificial intelligence to build audit and verification mechanisms for algorithms and their decisions.

What is explainable AI (XAI)?

Explainable AI refers to methods and tools that allow humans to understand and trust the results of machine learning models. According to the U.S. National Institute of Standards and Technology (NIST), the NIST is the only organisation in the U.S. that has a national standards body. The four key principles of Explainable Artificial Intelligence in the US are to ensure that AI systems are transparent, understandable and trusted by users:

• Explainability (Explainability): the AI must provide clear and understandable explanations of how it arrives at its decisions and recommendations.
• Meaningful (Meaningful): explanations must be meaningful and understandable to users.
• Accuracy (Accuracy): AI must generate accurate and reliable results, and the explanation of these results must accurately reflect its performance.
• Knowledge Limits (Knowledge Limits): AI must recognise when it does not have sufficient information or confidence in a decision and refrain from issuing responses in such cases.

Unlike traditional "black box" AI systems, which generate results without revealing their internal logic, XAI works on the traceability, interpretability and accountability of these decisions. For example, if a neural network rejects a loan application, XAI techniques can highlight the specific factors that influenced the decision. Thus, while a traditional model would simply return a numerical rating of the credit file, an XAI system could also tell us something like "Payment history (23%), job stability (38%) and current level of indebtedness (32%) were the determining factors in the loan denial". This transparency is vital not only for regulatory compliance, but also for building user confidence and improving AI systems themselves.

Key techniques in XAI

The Catalogue of trusted AI tools and metrics from the OECD's Artificial Intelligence Policy Observatory (OECD.AI) collects and shares tools and metrics designed to help AI actors develop trusted systems that respect human rights and are fair, transparent, explainable, robust, safe and reliable. For example, two widely adopted methodologies in XAI are Local Interpretable Model-agnostic Explanations (LIME) and SHapley Additive exPlanations (SHAP).

• LIME approximates complex models with simpler, interpretable versions to explain individual predictions. It is a generally useful technique for quick interpretations, but not very stable in assigning the importance of variables from one example to another.
• SHAP quantifies the exact contribution of each input to a prediction using game theory principles. This is a more precise and mathematically sound technique, but much more computationally expensive.

For example, in a medical diagnostic system, both LIME and SHAP could help us interpret that a patient's age and blood pressure were the main factors that led to a diagnosis of high risk of infarction, although SHAP would give us the exact contribution of each variable to the decision.

One of the most important challenges in XAI is to find the balance between the predictive ability of a model and its explainability. Hybrid approaches are therefore often used, integrating a posteriori explanatory methods of decision making with complex models. For example, a bank could implement a deep learning system for fraud detection, but use SHAP values to audit its decisions and ensure that no discriminatory decisions are made.

Open data in the XAI

There are at least two scenarios in which value can be generated by combining open data with explainable artificial intelligence techniques:

• The first of these is the enrichment and validation of the explanations obtained with XAI techniques. Open data makes it possible to add layers of context to many technical explanations, which is also true for the explainability of AI models. For example, if an XAI system indicates that air pollution influenced an asthma diagnosis, linking this result to open air quality datasets from patients' areas of residence would allow validation of the correctness of the result.
• Improving the performance of AI models themselves is another area where open data brings value. For example, if an XAI system identifies that the density of urban green space significantly affects cardiovascular risk diagnoses, open urban planning data could be used to improve the accuracy of the algorithm.

It would be ideal if AI model training datasets could be shared as open data, so that it would be possible to verify model training and replicate the results. What is possible, however, is the open sharing of detailed metadata on such trainings as promoted by Google's Model Cards initiative, thus facilitating post-hoc explanations of the models' decisions. In this case it is a tool more oriented towards developers than towards the end-users of the algorithms.

In Spain, in a more citizen-driven initiative, but equally aimed at fostering transparency in the use of artificial intelligence algorithms, the Open Administration of Catalonia has started to publish comprehensible factsheets for each AI algorithm applied to digital administration services. Some are already available, such as the AOC Conversational Chatbots or the Video ID for Mobile idCat.

Real examples of open data and XAI

A recent paper published in Applied Sciences by Portuguese researchers exemplifies the synergy between XAI and open data in the field of real estate price prediction in smart cities. The research highlights how the integration of open datasets covering property characteristics, urban infrastructure and transport networks, with explainable artificial intelligence techniques such as SHAP analysis, unravels the key factors influencing property values. This approach aims to support the generation of urban planning policies that respond to the evolving needs and trends of the real estate market, promoting sustainable and equitable growth of cities.

Another study by researchers at INRIA (French Institute for Research in Digital Sciences and Technologies), also on real estate data, delves into the methods and challenges associated with interpretability in machine learning based on linked open data. The article discusses both intrinsic techniques, which integrate explainability into model design, and post hoc methods that examine and explain complex systems decisions to encourage the adoption of transparent, ethical and trustworthy AI systems.

As AI continues to evolve, ethical considerations and regulatory measures play an increasingly important role in creating a more transparent and trustworthy AI ecosystem. Explainable artificial intelligence and open data are interconnected in their aim to foster transparency, trust and accountability in AI-based decision-making. While XAI provides the tools to dissect AI decision-making, open data provides the raw material not only for training, but also for testing some XAI explanations and improving model performance. As AI continues to permeate every facet of our lives, fostering this synergy will contribute to building systems that are not only smarter, but also fairer.

Housing is one of the main concerns of Spanish citizens, according to the January 2025 barometer of the Centro de Investigaciones Sociológicas (CIS). In order to know the real situation of access to housing, it is necessary to have public, updated and quality data, which allows all the actors in this ecosystem to carry out analyses and make informed decisions.

In this article we will review some examples of available open data, as well as tools and solutions that have been created based on them to bring this information closer to citizens.

Examples of housing data Open data can have several uses in this sector:

• Enable public bodies to understand citizens' needs and develop policies accordingly.
• Helping individuals to find homes to rent or buy.
• Providing information to builders and companies so that they can develop housing that responds to these needs.

Therefore, in this field, the most used data include those referring to housing, but also to demographic and social aspects, often with a high geospatial component. Some of the most popular datasets in this sense are the Housing and Consumer Price Indexes of the National Statistics Institute (INE) or the Cadastre data.

Different public bodies have made available to the public spaces where they gather various data related to housing. This is the case of Barcelona City Council and its portal "Housing in data", an environment that centralises access to information and data from various sources, including datasets from its open data portal.

Another example is the Madrid City Council data visualisation portal, which includes dashboards with information on the number of residential properties by district or neighbourhood, as well as their cadastral value, with direct access to download the data used.

Further examples of bodies that also provide access to this type of information are the Junta de Castilla y León, the Basque Government or the Comunidad Valenciana. In addition, those who wish to do so can find a multitude of data related to housing in the National Catalogue of Open Data, hosted here, at datos.gob.es.

It should also be noted that it is not only public bodies that open data related to this subject. A few months ago, the real estate portalidealistareleased a dataset with detailed information on thousands of properties in Madrid, Barcelona and Valencia. It is available as a package in R via Github.

Tools and solutions to bring this data closer to citizens

Data such as the above can be reused for multiple purposes, as we showed in previous articles and as we can see in this new approach to the various use cases:

Data journalism

The media use open housing data to provide a more accurate picture of the housing market situation, helping citizens understand the dynamics affecting prices, supply and demand. By accessing data on price developments, housing availability or related public policies, the media can generate reports and infographics that explain in an accessible way the situation and how these factors impact on people's daily lives. These articles provide citizens with relevant information, in a simple way, to make decisions about their housing situation.

One example is this article which allows us to visualise, neighbourhood by neighbourhood, the price of rent and access to housing according to income, for which open data from the Ministry of Housing and Urban Agenda, the Cadastre and the INE, among others, were used. Along the same lines is this article on the percentage of income to be spent on rent.

Reporting and policy development

Open data on housing is used by public bodies such as the Ministry of Housing and Urban Agenda in its Housing and Land Observatory, where electronic statistical bulletins are generated that integrate data available from the main official statistical sources. The aim is to monitor the sector from different perspectives and throughout the different phases of the process (land market, built products, accessibility and financing, etc.). The Ministry of Housing and Urban Agenda also uses data from various sources, such as the Tax Agency, the Cadastre or the INE, for its State Reference System of Housing Rental Prices, which defines ranges of rental price values for housing in areas declared as stressed.

Offer of real estate services

Open data can be valuable for the construction sector: open information on land use and permits is consulted before excavation work is undertaken and new construction starts.

In addition, some of the companies using open data are real estate websites. These portals reuse open data sets to provide users with comparable property prices, neighbourhood crime statistics or proximity to public educational, health and recreational facilities. This is helped, for example, by tools such as Location intelligence, which provides access to census data, rental prices, housing characteristics or urban planning. Public bodies can also help in this field with their own solutions, such as Donde Vivo, from the Government of Aragon, which allows you to obtain an interactive map and related information of the nearest points of interest, educational and health centres as well as geostatistical information of the place where you live.

There are also tools that help to forecast future costs, such as Urban3r, where users can visualise different indicators that help them to know the energy demand data of residential buildings in their current state and after undergoing energy refurbishment, as well as the estimated costs of these interventions.This is a field where data-driven disruptive technologies, such as  artificial intelligence, will play an increasingly important role, optimising processes and facilitating decision-making for both home buyers and suppliers. By analysing large volumes of data, AI can predict market trends, identify areas of high demand or provide personalised recommendations based on the needs of each user. Some companies have already launched chatbots, which answer users' questions, but AI can even help create projects for the development of affordable and sustainable housing.

In short, we are in a field where new technologies are going to make it easier and easier for citizens to find out about the supply of housing, but this supply must be aligned with the needs of users. It is therefore necessary to continue promoting the opening up of quality data, which will help to understand the situation and promote public policies and solutions that facilitate access to housing.

The Sistema Nacional de Publicidad de Subvenciones y Ayudas Públicas (SNPSAP) is a tool that contributes to the transparency, dissemination and re-use of data related to public subsidies and grants. This system centralises all the information on calls for applications and concessions of subsidies and public aid approved by the General State Administration, the autonomous communities and local entities.

Origins of the project

We have to go back to 2014 to find the beginning of this project. That year saw a reform of the 2003 General Law on Subsidies (Law 38/2003) with a huge impact in two significant respects:

• On the one hand, the National Subsidies Database, which had been created by the aforementioned Law in 2003, became available for full consultation by the managing bodies of subsidies and grants of all public administrations and those others legally authorised.

• Moreover, the National System of Publicity of Public Subsidies and Grants was created as a public website, with free and unrestricted access for all citizens. This complied with the requirements of publicity and transparency of all public subsidies and aid granted in Spain, especially calls for applications and awards, with identification of the beneficiaries. This space began operating on 1 January 2015, offering data from the state administration. The following year it was extended to regional and local administrations, thus covering the entire spectrum of the public sector.

Initial data formats and functionalities

From its origin, there was a serious support for the re-use of data for the society that originates it. Already initially the website allowed  downloading of data in different formats (CSV, XLSX and PDF) that allow their reuse, although limiting the size of the downloads to 10,000 records for performance and technical capacity reasons.

In addition, a alert subscription mechanismwas available from the outset. A citizen or company could - and can - register as many alerts as they need so that the system automatically notifies them when any call of interest to them is published, sending them a link to it. The tedious need to consult the dozens of official newspapers published in Spain on a daily basis to find out about calls for grants and subsidies was thus eliminated at a stroke.

A project in constant evolution to cope with growth

Regulatory developments in the field of aid and subsidies in the European Union, and Spain's accession to the United Nations Open Government Partnership initiative, shaped the growth of the website in successive years, increasing the offer of specific data views (State aid and minimis, large beneficiaries, political parties, etc.), which made it easier for citizens and data reusers to access them.

At the dawn of the pandemic, the system was already supporting 1.3 million visits per year, serving 3.3 million pages of grants and calls for proposals. This posed a challenge in terms of performance, as volumes never foreseen in the initial technical designs were achieved. A deep technological reform was needed to support the high demand for information and service level.

The reform was approached not only from a technological point of view, but also taking into account:

• The new features established in the Royal Decree 130/2019 regulating the National Grants Database.
• The socially demanded need to enable a API-REST interface for downloading information in reusable JSON format to overcome technical limitations.

Characteristics of the current platform

The new website was put into production at the end of November 2023, offering multiple views of calls for proposals (520,000 as of December 2024), grants (27,700,000), State aid awards (5.000,000), grants of minimis (3,190,000), strategic grant plans (1,341), very serious infringements (4), grants to parties (7,580), and grants to large beneficiaries (145,000).

All this information is accessible today via screen, downloadable in PDF, CSV, XSLX and API-REST interface formats in JSON and XML, being freely reusable by infomediary companies and citizens, with no restrictions other than those established by law.

Figure 1. Capture of the website of the National System for the Publicity of Public Subsidies and Grants (SNPSAP).

Since it went into production 11 months ago, the new system has received 7.5 million visits from citizens and businesses. And through the API-REST interface, thousands of downloads are made daily, making a powerful contribution to the dissemination of "raw" subsidy information for reuse by society for all kinds of analyses, studies, etc. In addition, an average of 35,000 e-mail alerts are issued daily to citizens and companies to inform them of new calls for subsidies.

Advantages of SNPSAP

The social dissemination and reuse of all this information eliminates asymmetries and frictions in the markets, and allows operators and citizens to work more efficiently and productively, resulting in higher levels of welfare for society.

The publication of open data allows citizens and organisations not only to know how public funds are distributed, but also to identify new opportunities. This system ensures that all individuals and organisations have equal access to information, regardless of their size or resources, contributing to a more equitable distribution of public support.

Geospatial data capture is essential for understanding our environment, making informed decisions and designing effective policies in areas such as urban planning, natural resource management or emergency response. In the past, this process was mainly manual and labour-intensive, based on ground measurements made with tools such as total stations and levels. Although these traditional techniques have evolved significantly and are still widely used, they have been complemented by automated and versatile methods that allow more efficient and detailed data collection.

The novelty in the current context lies not only in technological advances, which have improved the accuracy and efficiency of geospatial data collection, but also because it coincides with a widespread shift in mindset towards transparency and accessibility. This approach has encouraged the publication of the data obtained as open resources, facilitating their reuse in applications such as urban planning, energy management and environmental assessment. The combination of advanced technology and an increased awareness of the importance of information sharing marks a significant departure from traditional techniques.

In this article, we will explore some of the new methods of data capture, from photogrammetric flights with helicopters and drones, to ground-based systems such as mobile mapping, which use advanced sensors to generate highly accurate three-dimensional models and maps. In addition, we will learn how these technologies have empowered the generation of open data, democratising access to key geospatial information for innovation, sustainability and public-private collaboration.

Aerial photogrammetry: helicopters with advanced sensors

In the past, capturing geospatial data from the air involved long and complex processes. Analogue cameras mounted on aircraft generated aerial photographs that had to be processed manually to create two-dimensional maps. While this approach was innovative at the time, it also had limitations, such as lower resolution, long processing times and greater dependence on weather and daylight. However, technological advances have reduced these restrictions, even allowing operations at night or in adverse weather conditions.

Today, aerial photogrammetry has taken a qualitative leap forward thanks to the use of helicopters equipped with state-of-the-art sensors. The high-resolution digital cameras allow images to be captured at multiple angles, including oblique views that provide a more complete perspective of the terrain. In addition, the incorporation of thermal sensors and LiDAR (Light Detection and Ranging) technologies adds an unprecedented layer of detail and accuracy. These systems generate point clouds and three-dimensional models that can be integrated directly into geospatial analysis software, eliminating much of the manual processing.

Figure 1. Table with advantages and disadvantages of aerial photogrammetry with helicopters.

Mobile mapping: from backpacks to BIM integration

The mobile mapping is a geospatial data capture technique using vehicles equipped with cameras, LiDAR scanners, GPS and other advanced sensors. This technology allows detailed information to be collected as the vehicle moves, making it ideal for mapping urban areas, road networks and dynamic environments.

In the past, topographic surveys required stationary measurements, which meant traffic disruptions and considerable time to cover large areas. In contrast, mobile mapping has revolutionised this process, allowing data to be captured quickly, efficiently and with less impact on the environment. In addition, there are portable versions of this technology, such as backpacks with robotic scanners, which allow access to pedestrian or hard-to-reach areas.

Figure 3. Table with advantages and disadvantages of mobile mopping.

The mobile mapping is presented as a versatile and efficient solution for capturing geospatial data on the move, becoming a key tool for the modernisation of urban and territorial management systems.

HAPS and ballons: new heights for information capture

HAPS (High-Altitude Platform Stations) and hot-air balloons represent an innovative and efficient alternative for capturing geospatial data from high altitudes. These platforms, located in the stratosphere or at controlled altitudes, combine features of drones and satellites, offering an intermediate solution that stands out for its versatility and sustainability:

• HAPS, like zeppelins and similar aircraft, operate in the stratosphere, at altitudes between 18 and 20 kilometres, allowing a wide and detailed view of the terrain.
• The aerostatic balloons, on the other hand, are ideal for local or temporary studies, thanks to their easiness of deployment and operation at lower altitudes.

Both technologies can be equipped with high-resolution cameras, LiDAR sensors, thermal instruments and other advanced technologies for data capture.

Figure 4. Table with advantages and disadvantages of HAPS and ballons

HAPS and balloons are presented as key tools to complement existing technologies such as drones and satellites, offering new possibilities in geospatial data collection in a sustainable, flexible and efficient way. As these technologies evolve, their adoption will expand access to crucial data for smarter land and resource management.

Satellite technology: PAZ satellite and its future with PAZ-2

Satellite technology is a fundamental tool for capturing geospatial data globally. Spain has taken significant steps in this field with the development and launch of the PAZ satellite. This satellite, initially designed for security and defence purposes, has shown enormous potential for civilian applications such as environmental monitoring, natural resource management and urban planning.

PAZ is an Earth observation satellite equipped with a synthetic aperture radar (SAR), which allows high-resolution imaging, regardless of weather or light conditions.

The upcoming launch of PAZ-2 (planned for 2030) promises to further expand Spain''s observation capabilities. This new satellite, designed with technological improvements, aims to complement the functions of PAZ and increase the availability of data for civil and scientific applications. Planned improvements include:

• Higher image resolution.
• Ability to monitor larger areas in less time.
• Increased frequency of captures for more dynamic analysis.

Figure 5. Table with advantages and disadvantages of PAZ and PAZ-2 satellite technology

With PAZ and the forthcoming PAZ-2, Spain strengthens its position in the field of satellite observation, opening up new opportunities for efficient land management, environmental analysis and the development of innovative solutions based on geospatial datas. These satellites are not only a technological breakthrough, but also a strategic tool to promote sustainability and international cooperation in data access.

Conclusion: challenges and opportunities in data management 

The evolution of geospatial data capture techniques offers a unique opportunity to improve the accuracy, accessibility and quality of data, and in the specific case of open data, it is essential to foster transparency and re-use of public information. However, this progress cannot be understood without analysing the role played by technological tools in this process.

Innovations such as LiDAR in helicopters, Mobile Mapping, SAM, HAPS and satellites such as PAZ and PAZ-2 not only optimise data collection, but also have a direct impact on data quality and availability.

In short, these technological tools generate high quality information that can be made available to citizens as open data, a situation that is being driven by the shift in mindset towards transparency and accessibility. This balance makes open data and technological tools complementary, essential to maximise the social, economic and environmental value of geospatial data.

This meeting, to be held on 19-20 March 2025, will bring together experts, practitioners, developers, researchers and policy makers to share knowledge, explore new opportunities and address the challenges facing the open data community.

The event, organised by the European Commission through data.europa.eu, aims to promote the re-use of open data. Participants will have the opportunity to learn about the latest trends in the use of open data, discover new tools and discuss the policies and regulations that are shaping the digital landscape in Europe.

Where and when does it take place?

El evento se celebrará en el Centro Europeo de Convenciones de Luxemburgo, aunque también se podrá seguir online, con el siguiente horario:

• Wednesday 19 March 2025, from 13:30 to 18:30.
• Thursday 20 March 2025, from 9:00 to 15:30.

What issues will be addressed?

The agenda of the event is already available, where we find different themes, such as, for example:

• Success stories and best practices: the event will be attended by professionals working at the frontline of European data policy to share their experience. Among other issues, these experts will provide practical guidance on how to inventory and open up a country's public sector data, address the work involved in compiling high-value datasets or analyse perspectives on data reuse in business models. Good practices for quality metadata or improved data governance and interoperability will also be explained.
• Focus on the use of artificial intelligence (AI): open data offers an invaluable source for the development and advancement of AI. In addition, AI can optimise the location, management and use of this data, offering tools to help streamline processes and extract greater insight. In this regard, the event will address the potential of AI to transform open government data ecosystems, fostering innovation, improving governance and enhancing citizen participation. The managers of Norway's national data portal will tell how they use an AI-based search engine to improve data localisation. In addition, the advances in linguistic data spaces and their use in language modelling will be explained, and how to creatively combine open data for social impact will be explored.
• Learning about data visualisation: event attendees will be able to explore how data visualisation is transforming communication, policy making and citizen engagement. Through various cases (such as the family tree of 3,000 European royals or UNESCO's Intangible Cultural Heritage relationships) it will show how iterative design processes can uncover hidden patterns in complex networks, providing insights into storytelling and data communication. It will also address how design elements such as colour, scale and focus influence the perception of data.
• Examples and use cases: multiple examples of concrete projects based on the reuse of data will be shown, in fields such as energy, urban development or the environment. Among the experiences that will be shared is a Spanish company, Tangible Data, which will tell how physical data sculptures turn complex datasets into accessible and engaging experiences.

These are just some of the topics to be addressed, but there will also be discussions on open science, the role of open data in transparency and accountability, etc.
