Join us and build something that has the potential to make a difference to people's lives across the world. Location is a fundamental part of the apps on your phone and GIS is being used to show weather patterns, increase food production, detect traffic jams and more.

Developers can build any geo focused solution during the day and can participate in the challenges too:

  • Best use of ArcGIS
  • Best use of Pusher
  • Best use of aviation location data provided by Inmarsat
  • Other prizes will be awarded for special projects

Prizes available: A trip for 4 to the Emirates Aviation Experience in London with a meal at the Pilot Inn, Pebble watch, Parrot drones, Raspberry pis, Arduinos and more...



You must be 18 or over to participate in Geo Hack Day London.

You must be physically present at Geo Hack Day London.


Functioning demos are more powerful than slide decks but you can present your project in any way you think makes sense.
