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.
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.
This was a bit lost in the hubbub over the Google announcement, but a few weeks ago we added a feature to order a print directly from MapKnitter and from the PLOTS map archive. Users can now click-through directly from their map details page. Public Laboratory map production is working towards a end-to-end open source solution:
Planning. Getting started with Public Lab map tools, collaborate, learn about safety first
Capture. Taking aerial images
Sorting. Selecting the best images locally or online with mapmill.org

I got the MK111 timer all wired up and integrated into the PLOTS Visible/NIR Camera Tool payload. I still have to endurance test the two 4LR44 batteries, but I will wait to do that in the air -- no reason to waste two $1 batteries and not get any aerial photos.

Last week, Public Laboratory announced that public domain maps are now starting to show up on Google Earth and Google Maps. But how did the projects get there? Here's a timeline of a Public Laboratory map project.

To date, the documentation and open science literature we've made as a community has been published under a Creative Commons ShareAlike license, allowing anyone to reuse, remix, adapt, improve, and redistribute our works. Today, the PLOTS Web working group would like to propose that we as a community adopt a separate license for our hardware designs, and after much consultation, we'd like to adopt the CERN Open Hardware License.
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.
I've made an instructional video on efficient image sorting with Preview and Finder, for quickly winnowing down big groups of images to small sets, ready for MapKnitter:
This is a snapshot of some multispectral imaging that I have been working on with Pat Coyle at the organic agriculture park in Sunol, California. http://www.sagecenter.org/sunol-agpark/

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.
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.
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.
Techniques and tools for people who want to make maps, on the Public Laboratory wiki. Includes readings and case studies on grassroots mapping projects.
