Slovak hydrometeorological institute INSPIRE & OpenData

Team: Peter Hanečák, Kathi Schleidt, Tomáš Kliment


Project re-using meteorological data from Slovak hydrometeorological institute with aim to provide data as Open Data via CSV files as well as (INSPIRE aligned) services. The OGC SensorThings API, which has been proposed as an alternative download service within INSPIRE for the provision of measurement data, was utilized for data provision. In addition this project built a simple web map application based on this service, allowing the users to display stations on the map with information about the measurements and their values. Finally, the project is utilising the data to display them in graph representation.

Used data resources:

  1. Meteorological data available from Slovak hydrometeorological institute
  2. Open street map

Used technologies: SensorThings API, Data harvester, Open Layers

Additional info:

Open soil map

Team: Jakub Kočica, Boris Kružliak


Project built on top of Soil structure / quality data (Bonitované pôdnoekologické jednotky (BPEJ)) published by the National agricultural and food centre, containing the information about the soil quality and price. Result of the project is represented by the new map of soil types with the values of the soil price, published via machine readable OGC view service as well as by simple app providing the data via web browser.

Used data resources:

  1. Soil structure / quality data (Bonitované pôdnoekologické jednotky (BPEJ))

Used technologies: QGIS, PostgreSQL, Tabula, GeoServer, Excell, Notepad

Additional info:

Historical changes of Bratislava based on maps

Team: Boris Kružliak, Martin Zeman, Ondrej Kozlovsky


Project provides map apps on top of vectorised historical raster maps (geoportal.gov.sk), providing the visualisation of land cover in five time periods within the Bratislava as well as visualisation of the buildings coverage in three time periods across the Bratislava city centre.

Used data resources:

  1. Vectorised layers of historical maps
  2. Open street map

Used technologies: Postgre, Geoserver, Leaflet

Main ambition is to support the apps development, built on top of re-use of open data and application programming interface(API) of public sector organisations. 2017 starts the new era in openning of public sector data based on set of Resolutions of the Government of the Slovak Republic (104/2017 a 346/2017 - SK only). Although the process of data oppening has just started, set of datasets is being made available as open data via SK Open Data Portal. The amount will rise, butt it's necessary to search for evidence, this effort makes sense. Therefore set of public sector authorities has joined forces in order to find out:

  • whether it's possible to create new apps, data, services, as well as jobs on top of open data, APIs and technologies,
  • ako ich efektívne využiť pre zlepšenie Štátneho IT (eGovernment)how these effectively utilize in order to improve State IT (eGovernment) in development and use of apps and services with added value,
  • verify possibilities of open spatial data and API, including the potencial of INSPIRE infrastructure.

To proof that there is potential, present what’s behind you and your mates! Identify the possibilities, pitch ideas, promote your data, re-use available open data, API & software technologies to create new data, software, apps, or visualisations! And last but not least meet new people and spent two days in Bratislava just before the Christmas.

What means DanubeHack 3.0?

DanubeHack 3.0 is the third edition of the Hackathon organised in Bratislava (Slovakia) as follow up of the DanubeHack 2015, 2016. Main aim of the DanubeHack 3.0 is 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 Saturday morning (16th of December 2017) and will last till Sunday evening (17th of December 2017). 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 was possible via registration form.

Hackathon and Open Data Academy

Hackathon will be primarily focused on implementation of the ideas presented and supported by the teams created from the participants at the beginning. Open Data Academy will provide the small enrichment of the event with the short inspirative contributions for the relevant topics.

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: Supporters 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 (Support with the Programme, Data, Technologies, Promotional support, Awards for winners, Provision of mentors or members of jury);
  • Partners: With indirect contribution (Support with the Programme, Data, Technologies, Promotional support, Awards for winners, Provision of mentors or members of jury).

How much will event cost me?
