There are a number of geo-related events coming up this week.
If you are in the Mountain View area today you could pop along to Random Hacks of Kindness. Random Hacks of Kindness is an initiative bringing together disaster relief experts and software engineers to work on identifying key challenges to disaster relief, and developing solutions to these critical issues.
If you are in Denmark (Nov 18-19) then you shouldn't miss Kortdage (Map Days). This is a major conference with 47 speakers. As part of the conference there will be a 24 hours mashup competition to use free public data and free tools and web services to create on-line maps.
If you happen to be in London on Thursday (19th) then you can attend the latest Geomob meet. There will be presentations at the event from CloudMade, mapme.at, Mapstraction, Skyhook Wireless and Jaggeree.
In New York on Friday (20th) there is a Google Hackathon. This should be a great event for anyone interested in Google's geo-related APIs.
