Once again, the Junta de Castilla y León has launched its open data contest to reward the innovative use of public information.

In this post, we summarize the details to participate in the IX edition of this event, which is an opportunity for both professionals and students, creative people or multidisciplinary teams who wish to give visibility to their talent through the reuse of public data.

What does the competition consist of?

The aim of the competition is to recognize projects that use open datasets from the Junta de Castilla y León. These datasets can be combined, if the participants wish, with other public or private sources, at any level of administration.

Projects can be submitted in four categories:

• Ideas category: aimed at people or teams who want to submit a proposal to create a service, studio, application, website or any other type of development. The project does not need to be completed; the important thing is that the idea is original, viable and has a potential positive impact.
• Products and services category: designed for projects already developed and accessible to citizens, such as online services, mobile applications or websites. All developments must be available via a public URL. This category includes a specific award for students enrolled in official education during the 2024/2025 or 2025/2026 school years.
• Didactic resource category: aimed at educational projects that use open data as a support tool in the classroom. The aim is to promote innovative teaching through Creative Commons licensed resources, which can be shared and reused by teachers and students.
• Data journalism category: it will reward journalistic works published or updated in a relevant way, in written or audiovisual format, that make use of open data to inform, contextualize or analyze topics of interest to citizens. The journalistic pieces must have been published in a printed or digital media since September 24, 2024, the day following the end date of the deadline for submission of candidacies of the immediately preceding call for awards.

In all categories, it is essential that at least one dataset from the open data portal of the Junta de Castilla y León is used. This platform has hundreds of datasets on different sectors such as the environment, economy, society, public administration, culture, education, etc. that can be used as a basis to develop useful, informative and transformative ideas.

Who can participate?

The competition is open to any natural or legal person, who can be presented individually or in a group. In addition, you can submit more than one application even for different categories. Although the same project may not receive more than one award, this flexibility allows the same idea to be explored from different approaches: educational, journalistic, technical or conceptual.

What prizes are awarded?

The 2025 edition of the contest includes prizes with a financial endowment, accrediting diploma and institutional dissemination through the open data portal and other communication channels of the Board.

The distribution and amount of the prizes by category is:

• Ideas category
  
  • First prize: €1,500
  • Second prize: €500
• Category products & services
  
  • First prize: €2,500
  • Second prize: €1,500

Each application must include:

• Identification data of the author(s).
• Title of the project.
• Category or categories to which it is submitted.
• An explanatory report of the project, with a maximum length of 1,000 words, providing all the information that can be assessed by the jury according to the established scale.
• In the case of submitting an application to the Products and Services category, the URL to access the project will be specified

The deadline to submit proposals is September 22, 2025

With this contest, the Junta de Castilla y León reaffirms its commitment to the open data policy and the culture of reuse. The competition not only recognizes the creativity, innovation and usefulness of the projects presented, but also contributes to disseminating the transformative potential of open data in areas such as education, journalism, technology or social entrepreneurship.

In previous editions, solutions to improve mobility, interactive maps on forest fires, tools for the analysis of public expenditure or educational resources on the rural environment, among many other examples, have been awarded. You can read more about last year's winning proposals and others on our website. In addition, all these projects can be consulted in the history of winners available on the community's open data portal.

We encourage you to participate in the contest and get the most out of open data in Castilla y León!

Madrid City Council has launched an initiative to demonstrate the potential of open data: the first edition of the Open Data Reuse Awards 2025. With a total budget of 15,000 euros, this competition seeks to promote the reuse of the data shared by the council on its open data portal, demonstrating that they can be a driver of social innovation and citizen participation.

The challenge is clear: to turn data into useful, original and impactful ideas. If you think you can do it, below, we summarize the information you must consider to compete.

Who can participate?

The competition is open to practically everyone: from individuals to companies or groups of any kind. The only condition is to submit a project carried out between September 10, 2022 and September 9, 2025 and that uses at least one dataset  from the Madrid City Council's open data portal as a base. Data from other public and private sources can also be used, as long as the  Madrid City Council datasets are a key part of the project.

Of course, projects that have already been awarded, contracted or financed by the City Council itself are not accepted, nor are works submitted after the deadline or without the required documentation.

What projects can be submitted?

There are four main areas in which you can participate:

• Web services and applications: refers to projects that provide services, studios, web applications, or mobile apps.
• Studies, research and ideas: refers to projects of exploration, analysis or description of ideas aimed at the creation of services, studies, visualizations, web applications or mobile apps. Bachelor's and master's degree final university projects can also participate in this category.
• Proposals to improve the quality of the open data portal: includes projects, services, applications or initiatives that contribute to boosting the quality of the datasets published on the Madrid City Council's open data portal.
• Data visualizations: you can participate in this category with various content, such as maps, graphs, tables, 3D models, digital art, web applications and animations. Representations can be static, such as infographics, posters, or figures in publications, or dynamic, including videos, interactive dashboards, and stories.

What are the prizes?

For each category, two prizes for different economic endowments are awarded:

Beyond the economic prize, this call is a great opportunity to give visibility to ideas that take advantage of the transparency and potential of open data. In addition, if the proposal improves public services, solves a real problem or helps to better understand the city, it will have great value that goes far beyond recognition.

How are projects valued?

A jury will evaluate each project by assigning a maximum score of 50 points, which will take into account aspects such as originality, social benefit, technical quality, accessibility, ease of use, or even design, in the case of visualizations. If deemed necessary, the jury may request further information submitted to the participants.

The two projects with the highest score will win, although to be considered, the proposals must reach at least 25 points out of a possible 50. If none of them meets this requirement, the category will be declared void.

The jury will be made up of representatives from different areas of the City Council, with experience in innovation, transparency, technology and data. A representative of ASEDIE (Multisectoral Association of Information), the association that promotes the reuse and distribution of information in Spain, will also participate.

How do I participate?

The deadline to register is September 9, 2025 at 11:59 p.m. In the case of natural people, the application can be submitted:

• Online through the City Council's Electronic Office. This procedure requires identification and electronic signature.
• In person at municipal service offices.

In the case of legal people, they may only submit their candidacy electronically.

In any case, the official form must be completed and accompanied by a report explaining the project, its operation, its benefits, the use of the data, and if possible, including screenshots, links or prototypes.

You can see the complete rules here.

From Gijón to the world: the Spanish project awarded in 2024

In last year's edition, a Spanish project, specifically from Gijón, won the global award for best mission concept with its Landsat Connect application proposal. The AsturExplorer team developed a web application designed to provide a fast, simple and intuitive way to track the path of Landsat satellites and access surface reflectance data. Their project fostered interdisciplinary and scientific learning capacities, and empowered citizens.

The Landsat program consists of a series of Earth observation satellite missions, jointly managed by NASA and the U.S. Geological Survey (USGS), providing images and data about our planet since 1972.

End users of the app developed by AsturExplorer can set a destination location and receive notifications in advance to know when the Landsat satellite will pass over each area. This allows users to prepare and take their own measurements on the ground and obtain pixel data without the need to constantly monitor satellite schedules.

The AsturExplorer team used open Landsat data from NASA and Earth Explorer. They also made use of artificial intelligence to understand the technical problem and compare multiple alternatives. You can read more about this use case here.

We encourage you to be part of this global benchmark event where you will reuse open datasets. A great opportunity!

Bizidata is a platform that visualises, analyses and allows you to download data on bicycle use in Vitoria-Gasteiz and explore how external factors, such as weather and traffic, influence bicycle use.

This application collects and combines the following data: 

• Bicycle use: data from the Vitoria-Gasteiz City Council.
• Temperature between 2015 and 2021: Aemet data.
• Temperatures between 2022 and today: Euskalmet (station C040).
• Precipitation: Euskalmet (station C076). 
•   Traffic: Traffic Directorate of the Basque Government. 

Bizidata was the winning application in the web services category of the Euskadi 2024 Open Data Competition. 

Tupreciodeluz.com offers daily information on the price of electricity, showing the cheapest price of the day, as well as the average price of the last 24 hours and the most expensive time slot. The aim is to allow consumers adhering to the regulated market tariff (PVPC) to modulate their consumption in order to save on their electricity bill.

The website also features an artificial intelligence assistant for energy advice, and measures to promote efficiency and responsible energy consumption.

In addition, consumers can use a solar sizer to find out the feasibility of installing solar energy in their home or business.

The website also has a blog where the most relevant news for consumers is published in a summarised and entertaining way.

Many people use apps to get around in their daily lives. Apps such as Google Maps, Moovit or CityMapper provide the fastest and most efficient route to a destination. However, what many users are unaware of is that behind these platforms lies a valuable source of information: open data. By reusing public datasets, such as those related to air quality, traffic or public transport, these applications can provide a better service.

In this post, we will explore how the reuse of open data by these platforms empowers a smarter and more  sustainable urban ecosystem .

Google Maps: aggregates air quality information and transport data into GTFS.

More than a billion people use Google Maps every month around the world. The tech giant offers a free, up-to-date world map that draws its data from a variety of sources, some of them open.

One of the functions provided by the app is information about the air quality in the user's location. The Air Quality Index (AQI) is a parameter that is determined by each country or region. The European benchmark can be consulted on this map which shows air quality by geolocated zones in real time.

To display the air quality of the user's location, Google Maps applies a model based on a multi-layered approach known as the "fusion approach". This method combines data from several input sources and weights the layers with a sophisticated procedure. The input layers are:

• Government reference monitoring stations
• Commercial sensor networks
• Global and regional dispersion models
• Dust and smoke fire models
• Satellite information
• Traffic data
• Ancillary information such as surface area
• Meteorology

In the case of Spain, this information is obtained from open data sources such as the Ministry of Ecological Transition and Demographic Challenge, the Regional Ministry of Environment, Territory and Housing of the Xunta de Galicia or the Community of Madrid. Open data sources used in other countries around the worldcan be found here .

Another functionality offered by Google Maps to plan the best routes to reach a destination is the information on public transport. These data are provided on a voluntary basis by the public companies providing transport services in each city. In order to make this open data available to the user, it is first dumped into Google Transit and must comply with the open public transport standard GTFS (General Transit Feed Specification).

Moovit: reusing open data to deliver real-time information

Moovit is another urban mobility app most used by Spaniards, which uses open and collaborative data to make it easier for users to plan their journeys by public transport.

Since its launch in 2012, the free-to-download app offers real-time information on the different transport options, suggests the best routes to reach the indicated destination, guides users during their journey (how long they have to wait, how many stops are left, when they have to get off, etc.) and provides constant updates in the event of any alteration in the service.

Like other mobility apps , it is also available in offline mode and allows you to save routes and frequent lines in "Favourites". It is also an inclusive solution as it integrates VoiceOver (iOs) or TalkBack (Android) for blind people.

The platform not only leverages open data provided by governments and local authorities, but also collects information from its users, allowing it to offer a dynamic and constantly updated service.

CityMapper: born as a reuser of open mobility data

The CityMapper development team recognises that the application was born with an open DNA that still remains. They reuse open datasets from, for example, OpenStreetMap at global level or RENFE and Cercanías Bilbao at national level. As the application becomes available in more cities, the list of open data reference sources from which it draws information grows.

The platform offers real-time information on public transport routes, including bus, train, metro and bike sharing. It also adds options for walking, cycling and ridesharing. It is designed to provide the most efficient and fastest route to a destinationby integrating data from different modes of transport into a single interface.

As we published in the monographic report "Municipal Innovation through Open Data" CityMapper mainly uses open data from local transport authorities, typically using the GTFS (General Transit Feed Specification) standard . However, when this data is not sufficient or accurate enough, CityMapper combines it with datasets generated by the application's own users who voluntarily collaborate. It also uses data enhanced and managed by the work of the company's own local employees. All this data is combined with artificial intelligence algorithms developed to optimise routes and provide recommendations tailored to users' needs.

In conclusion, the use of open data in transport is driving a significant transformation in the mobility sector in cities. Through their contribution to applications, users can access up-to-date and accurate data, plan their journeys efficiently and make informed decisions. Governments, for their part, have taken on the role of facilitators by enabling the dissemination of data through open platforms, optimising resources and fostering collaboration across sectors. In addition, open data has created new opportunities for developers and the private sector, who have contributed with technological solutions such as Google Maps, Moovit or CityMapper. Ultimately, the potential of open data to transform the future of urban mobility is undeniable.

It is a website that compiles public information on the state of the different reservoirs in Spain. The user can filter the information by river basins and administrative units such as provinces or autonomous communities. 

The data are updated daily and are shown with percentages and graphs. In addition, it also offers information on rain gauges and the comparison between the percentage of water currently embasada and the one that existed a year ago and 10 years ago.  

Embales.net shares in a clear and understandable way open data obtained from AEMET and the Ministry of Ecological Transition and Demographic Challenge. 

Metrominuto is an application that provides its users with information on distances and times between the most important points of Pontevedra. It does this through a synoptic map, imitating the design of subway maps, installed in the city signage and also consultable through a mobile application. Among the app's functions, the following stand out: 

• Provides information on the distance, time and calories needed to reach a place in the city from the starting point according to the user's location. 
• Includes expanded information on points of interest on the map.  
• Proposes itineraries according to categories such as hiking, bicycle route, special routes, etc.  
• Allows to classify places as favorites.  
• It offers the user the possibility of pointing out mobility problems on the route. 

Metrominuto operates in the city of Pontevedra and uses information from its open data portal. 

This application designed for iOS devices offers a wide range of tourist activities in the Autonomous Community of Castilla y León. It acts as a travel assistant, allowing you to create an itinerary according to the interests of each user.

TUrMISMO allows you to discover activities to do in the area, save your favourite places or plans, and trace your own route. To do this, it offers geolocated information on places as diverse as tourist offices, restaurants and wineries, organised excursions and ski schools, among many others.

The app was presented this year 2024 to the VII Open Data Competition of Castilla y León and uses open data provided by the Junta de Castilla y León.
