Despite the increasing amount of the data that is created and made open in the Danube region, its practical use is still facing various challenges. In the case of geo data the situation is even more tricky. Similar conditions relate also to the software tools helping to collect, manipulate and publish such data.

To proof that there is potential in this data, present what’s behind you and your mates! Identify the possibilities, pitch ideas, promote your data, re-use available open data & software technologies to create new data, software, apps, or visualisations! Provide the proposals/expectations for workshops! And last but not least meet new people and spent two nights in Bratislava close to the Danube river.

Preliminary areas of Open data domains foreseen to be combined with identified geo data:


Air, water, soil, protected areas...

Transparent governance

Economy, Budgettary, Business...

Crime & Safety

Maps of crime, food quality...

Mobility & Transport

Public transport, cycling routes...

Other Areas

Bring and pitch them on Day 0!

What means DanubeHack?

DanubeHack is the first hackathon combined with the workshops organised in Bratislava (Slovakia) with the aim to create the space, where those with the interest in potential of Open (Geo) Data can meet, present their ideas, knowledge a discuss the possible ways of further cooperation or project ideas.

When will event take place?

Danube hack will last 2 days, starting on the Thursday evening (15th of October 2015) and will last till Saturday evening. For more detailed roadmap and updates in agenda, check regularly this website.

Who should consider to register?

Any enthusiasts willing to show, what can be done with available data and technologies as well as anybody with the interest in improvement or sharing the knowledge with related topics are more than welcome. The same applies for those willing to present available Open Data. Anyway, because of capacity limitations, organisers will evaluate the registration proposals in order to cover thematic and geographical scope of the event.

Why & how to register?

Main motivation to consider your participation should be the willingness to explore or demonstrate the potential of the Open (Geo) Data added value as well as share and collect related information, knowledge and experience. Data produces can also advertise their Open Data and get direct feedback from their users. Geo data by its nature provides spatial delineation for any phenomena we are facing these days. Therefore, despite the primary geodata focus any non - spatial data which can have direct on indirect linkage to location and space will be in scope, independently of their origin. The same will be applied for technology part of the event, where any perspective software platforms, solutions as well as approaches and methodologies will be more than welcome. Initial List of resources (covering identified data, catalogues and related tools) has been made available and will be updated by the organizers, supporters including input received from you. Registration is possible via registration form.

Hackathon or Workshops?

Whilst hackathon will be primarily focused on implementation of the ideas presented and selected at the beginning, workshops will offer set of platforms, where various related topics will be presented with aim to stimulate the discussion. Participation is possible on both events, but organisers will evaluate the input received during the registration in a way to ensure appropriate participation on both activities.

Why and how to support DanubeHack?

The success and quality of the event is closely linked with the received support and sponsoring. Event can provide unique opportunity to trigger promising ideas, gain new knowledge or uncover smart experts. Therefore, various modules of event supporters/sponsors have been identified:

  • Organisers: Authorities directly involved via financial funding and organising the event with the possibility to shape the scope and direction of the event;
  • Projects: With direct (Financial) or indirect contribution (Data, software, products, methodologies, capacity resources, networks, promotional support, prizes for winners, provision of qualified mentors or members of jury) with the possibility to present activities of their interest;
  • Partners: With direct (Financial) or indirect contribution (Data, software, products, methodologies, capacity resources, networks, promotional support, prizes for winners, provision of qualified mentors or members of jury) with the possibility to present activities of their interest.
  • Backers: Parties acting as sympathizers offering any additional needed support (promotional support, auspices, in kind / volunteering support during the event) with the room to receive appropriate recognition.

How much will DanubeHack cost me?

Participation is free of charge, based on the registration. Because of the capacity limitations, organisers will evaluate the registration proposals in order to cover thematic and geographical scope of the event. Selected participants will be contacted with further details.

Where & how I will get further updates?

Watch this space regularly, or follow the latest updates via Facebook .

Who else is going to be there?

To provide the support for the hackathon participants, group of mentors with expertise from wide set of domains will be on place to provide the guidance, where needed. Evaluation of the outcomes from the projects established during the hackathon will be undertaken by the panel of professional judges.

What do I need to bring?

There will be prepared essential set of foods and drinks for the whole event, including connection to the electric and internet networks. Hackathon participants shall bring their tools and enthusiasm. Workshops participants will be expected to actively contribute to the workshops with their questions and ideas.

Do I need to have a team?

Not at all. When the Hackathon kicks off, you’ll have the chance to pitch your idea to all participants, or to join a team you find interesting. Teams may combine or split up according to their interests and goals. Teams should consist of 2 to 5 people with diverse skills.

How can I get to the venue?

Hackathon will take place in ImpactHub located in the Bratislava centre. Transport options:
