Best Online Apps

The public were invited to vote for the best app, through an online form. The result, at least in the case of the first three places, is exactly the same as the final decision of the jury that evaluated all 7 applications in Riga during the event. The people’s choice of Best app of the Baltic Open (Geo) Data Hackathon 2016 is: Ideas and Data from Open Riga (Pavel Hajek, Jan Macura, František Kolovský, Dmitrii Kozuch, Agris Snepsts, Danis Kreilis).

The importance of open data and open geodata is increasing. But the potential of open (geo) data has not been fully exploited. This is true in most parts of Europe including the Baltic Region. Similar conditions relate also to the software tools helping to collect, manipulate and publish such data. There is a need to address these challenges and where possible to improve this situation. For this reason, the Baltic Open (Geo) Data Hackathon is organised.

In order to prove the potential of open (geo) data, your contributions, expertise and knowledge are needed! Identify possibilities of open (geo) data exploitation, pitch new ideas, promote your data, re-use available open (geo) data & software technologies to create new data, software, apps, or visualisations. Provide the proposals/expectations for the hackathon. And, last but not least, meet new people and spent three wonderful days in Riga.

Who we are looking for?

A hackathon is very often understood as some exercises of programmers or data specialists. The Baltic Open Data Hackathon extends this approach by inviting also end users. So we are looking for different types of developers, data specialists and users from different fields, not limited to the following ones:

  • Open data providers
  • Web GIS developers
  • Web designers
  • Semantic web experts
  • Database experts
  • User interaction experts
  • Mobile developers
  • Developers of apps in different areas like transport, tourism agriculture, planning
  • Hardware experts focused on sensors, communication and machinery tracking
  • GIS specialists for analysis
  • Geographers
  • Earth observation experts
  • Experts on land use, landscape and land cover
  • Spatial and urban planers
  • Transport planners and managers
  • Agronomist and farmers
  • Travel agencies and tourism specialists
  • Regional development agencies
  • Environment protection experts
  • Managers and investors interested to check or find new ideas
  • Marketing experts
  • Data journalists

Anyone of you can come with ideas and look for team members and data to realise your plans!

How to present your ideas?

You have two possibilities to present your ideas and attract potential team members:

  1. First, you can promote your ideas in advance through the SDI4Apps developers’ blog. All contributions will be distributed through LinkedIn and Facebook pages. This is a chance to discuss and prepare your project and build your team in advance.
  2. The second option is to present your idea during the hackathon. Everybody will be given a chance to prepare their own 5 minute pitch to attract other team members.

What data will be available?

The SDI4Apps, OpenTransportNet and FOODIE projects and other partners will provide sets of available open data. However, hackathon activities will not be limited to these data sets. A preliminary list of available data include:

  • Open Land Use (link 1, link 2)
  • Smart Points of Interest (link)
  • Open Transport Map (link)
  • Satellite data from Landsat and Copernicus
  • DanubeHack list of Data and Catalogues (link)
  • OpenStreetMap (link)

Data sources will be added here.

What tools will be available?

The SDI4Apps, OpenTransportNet and FOODIE projects will offer you also a set of tools and open source software, which will be able to help you with building new solutions. However, hackathon activities will not be limited to these tools and you are free to use any other tools you like. A preliminary list of tools includes:
