Grassroots Mapping is a series of participatory mapping projects involving communities in cartographic dispute. Seeking to invert the traditional power structure of cartography, the grassroots mappers used helium balloons and kites to loft their own “community satellites” made with inexpensive digital cameras.

Gulf Oil Spill Mapping

Map the oil spill with balloons and kites!

We’re helping citizens to use balloons, kites, and other simple and inexpensive tools to produce their own aerial imagery of the spill… documentation that will be essential for environmental and legal use in coming years.

We’re not trying to duplicate the satellite imagery or the flyover data (though we’re helping to coordinate some of the flyovers and trying to make sure the data is publicly accessible). We believe in complete open access to spill imagery and are releasing all imagery into the public domain.

Want to help?

We’re organizing mapping ‘trips’ to the coast. If you’re interested in participating in or leading a trip, please sign up on our Volunteer Form

Support our efforts!


We need some support for fuel, balloons, helium, cameras, and other expenses. Anything would help, please donate to support our activities. We’re not backed by a large organization (yet!) and donations are one of our only ways to cover expenses.

Where’s the imagery?

We’re posting imagery as fast as we can upload it. We’re also working on stitched maps; we should shortly be able to publish tilesets.

You can see all of our data (raw images in .zip files, GeoTiffs, KML, OpenLayers, and Flickr feeds) available for download at http://grassrootsmapping.org/data/.
You can also see a lot on Flickr with the tag “gulfoilmap”.

This work is dedicated to the Public Domain.

Also see some great imagery over at Western Carolina University’s Shutterfly site, thanks to Adam Griffith of WCU and coastalcare.org.
