Today, we had a balloon mapping experiment. For a very brief airtime, we got some really impressive images.

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/

Hello. I'm jaekyung lee from South Korea.
These days, I'm trying to get picture at 350 meters high.
Two weeks ago, at last I could get picture and return my camera and camcorder.
저는 한국의 이재경입니다. 퍼블릭라보라토리의 풍선맵핑을 참고하여 한국에서 도시맵핑 프로젝트를 진행했습니다. 약간은 방법에 차이는 있을 수 있지만, jeff의 방법 모델을 많이 참고했습니다. 한국에서 구하기 쉬운 재료를 사용했고 모든 내용은 퍼블릭 라보라토리와 구글 사이트도구에 한국어로 공유하였습니다.

Students, faculty, alumni, and the community in general gathered to voice their disapproval of the pepper spraying of non-violent protestors on campus. The photo here is unprocessed, but a stitched one will be coming soon! The photo was taken with Stewart's helium balloon using a point-and-shoot camera and a smart phone took video of the crowd. The crew: Stewart, Liz, Michele, and Alex.
Are you embroiled in an cartographic dispute? Do you disagree with the official version of your geography? Contact us through the public mailing list or get in direct touch with our team to start a grassroots mapping project today!
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.
You can see all of our data here: http://publiclaboratory.org/archive/.
Browse some of our best imagery on Flickr.
Techniques and tools for people who want to make maps, on the Public Laboratory wiki. Includes readings and case studies on grassroots mapping projects.
Instructions on how to use cameras on weather balloons to create high-resolution maps.
