Grassroots Mapping was started by the Public Laboratory for Open Technology and Science to produce aerial imagery of the effects of the Deepwater Horizon Oil Spill. The process they use is balloon mapping, a simplified and more immediate way to obtain aerial imagery, than by satellite or airplanes. In Louisiana these images are being submitted to the Public Laboratory Archive so we can all see the damages inflicted by this man-made disaster, but you can also buy a kit through their Kickstarter campaign and use it to map your neighborhood, pretty rad right?
