Put your GIS skills to good use at the CalGIS Mapathon. This evening activity will support the many projects of the Humanitarian OpenStreetMap Team (HOT).

Participants should bring a laptop and have some basic familiarity with OpenStreetMap.

With all of the recent natural disasters, the GIS Community has responded swiftly to project requests, including GPN's GISCorps. Projects for the mapathon may include any number of responses from current disasters impacting the world and as the event nears, we will narrow down the projects we will work on this evening.
