Balloon Mapping the Gulf Coast oil spill

In 2010, a community monitoring project in New Orleans led by activist group Louisiana Bucket Brigade got Gulf Coast residents out on boats and beaches to produce high-resolution aerial imagery of the effects of the BP oil spill. Using cameras mounted on helium balloons they took photos and stitched them together to create an aerial map which was then put in the public domain. The lack of information on the spill, combined with BP's dismal transparency and accountability, meant activists needed to produce their own evidence to support their campaign.
