Since May 2010, we have been using balloon mapping to capture aerial imagery of spill-affected sites in Louisiana, Mississippi, Alabama and Florida. Our work on the Gulf Coast has been done largely in cooperation with the Louisiana Bucket Brigade on a community-led monitoring of the Deepwater Horizon oil spill. The data we have gathered can be viewed at:

More images and information can be found at:

• http://unterbahn.com/thesis - Chapter 8: Case Study: Citizen mapping of the BP oil spill (5.7 mB, 14 pages)
• and in the various press and publications listed at http://publiclaboratory.org/media

We’re not trying to duplicate the satellite or flyover imagery (though we’ve helped to coordinate some of the flyovers and trying to ensure that the data is publicly accessible). We are helping Gulf Coast residents to use balloons, kites, and other simple and inexpensive tools to produce their own documentation of the spill… and hoping that such data collection will support environmental research, policy, and regulatory changes in coming years.

Current focuses (April 2011) include:

• Producing our first paper map (with the support of DevelopmentSeed) of Wilkinson Bay.
• Providing digital archives of collected images to libraries across the Gulf Coast
• Mapping at Helen Woods Park in Mobile Bay, Alabama where an oyster reef is being constructed by hundred of volunteers
• Continued mapping at sites in Louisiana including Grand Isle, Bay Jimmy, and in the Barataria region
• Connecting with researchers regarding data use and potential collaborations

We're organizing mapping 'trips' to the coast. If you're interested in participating in a trip or conducting your own mapping session, please contact us at the mailing list, and we'll help you get started. (equipment, training, finding volunteers, etc.)

Contact information

• Grassroots Mapping Mailing List - please join, this is how we can reach you with meeting announcements, etc.

How can you help?

• Sort imagery we've collected so that it can be stitched into maps
• Sponsor the printing of one of our maps to be distributed on the Gulf Coast
• Help us find boats in the Gulf Coast area for mapping trips
• Volunteers in the area to fly balloons/kites, make maps Volunteer Here

Equipment:

• Canon cameras or Android phones (see CameraOptions)
• Weather balloons (5 feet diameter or more)
• 100-gallon trash bags
• string, lots of string

Mapping Resources

• NOAA's latest prediction maps -- PDFs available for 24, 48, and 72 hour horizons
• Latest MODIS imagery - often cloud-obscured
• etc. mapping resources-- pulled from posts to grassrootsmapping google group

Other mapping efforts

• LA Bucket Brigade Ushahidi instance - see below for more on LABB
• CrisisCommons: Dr. Eric Frost, "Viz Lab" at SDSU San Diego: bio, crisismapping profile
• Skytruth is doing regular analysis of satellite imagery of the spill.
