Published on took place on Friday 26th of April 2013. It was a 5 hour long hackaton, where apps (web or mobile) will be developed with a focus on Geodata in Open Data format.

The aim of the day is to bring together Geo data-owners with application developers from enterprise , creative world… in order to get most out of the combination of available open geodatasets and aim for more open datasets. The day is also an interesting learning curve for public geo-authorities, data owners and other participants, in order to improve and ease the opening up of public data.
