Over the last year, we’ve build a global community of mappers who are engaged in civic issues with low-cost mapping tools like balloons, kites, and remote-control airplanes. We're helping citizens on the Gulf Coast use balloons and kites to produce their own aerial imagery of the Deepwater Horizon oil spill… documentation that will be essential for environmental and legal use in coming yeas.We believe in complete open access to spill imagery and are releasing all imagery from the oil spill mapping project into the public domain.
