Grassroots Mapping is a series of participatory mapping projects involving communities in cartographic dispute.

We had a great time flying at the workshop I gave on Saturday (above photo courtesy of Andrew A. Wagner); Nathan Craig was there with some kites and I got to check out his very nice kite aerial photography kit. He uses the same electric cable winder I do!

The conference was centered around the GigaPan tool, and so I learned a lot about 3D reconstruction of a scene from image collections… I hope to duplicate some of their techniques to derive 3D terrain maps from our balloon photos!

Here is a link to the entire set of aerial images we shot: (1 Gb)

And here’s one of the aerial photos we shot:
