At Public Lab, we've grown the Grassroots Mapping community into a broader effort to enable communities to understand and respond to environmental threats with DIY techniques.
Here is a prototype rig that performed well on its maiden flight. The design might be appropriate for matched visible/IR cameras for vertical photography, like the Canon A495s from the Balloon Mapping Kickstarter project. For such a use, it would require the addition of an intervalometer to trigger both cameras simultaneously. I am not yet sure how to add that function.

Grassroots Mapping is part of the Public Laboratory for Open Technology and Science, founded by a group of activists, educators, technologists, and community organizers interested in new ways to promote action, intervention, and awareness through a participatory research model.
We're now trying to learn from our balloon mapping experiences to develop new DIY tools with a variety of local communities. This is an open community and you are welcome to join, and encouraged to contribute!
Purchase the Grassroots Mapping Forum, our new community research journal/archive/zine/map, where we hope to share ideas, techniques, and stories from the Grassroots Mapping community. It is printed on a single 22.75x35" newsprint sheet, folded down to just over letter size, and includes a full color reproduction of a grassroots map along with essays, illustrated guides, and interviews on the reverse.
You can find out more, and purchase the first issue here for $17 shipped.
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 yeas.We believe in complete open access to spill imagery and are releasing all imagery into the public domain.
