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.

Hand-warper beta working – demo

March 24th, 2010 by Jeffrey Warren

Cartagen warping tool demo from Jeffrey Warren on Vimeo.

As promised in an earlier post, the hand-warping tool is online, although ‘beta’ may be a generous descriptor… lots of features are still coming, please be patient! Watch the above video for an introduction.

This is basically a tool for people to upload and easily stitch together their balloon- and kite-photos. I wanted to add that it’s optimized for ease-of-use, and even for folks with limited tech literacy — we’re working on other techniques for mass warping and stitching.

Suggestions or what-have-you can be posted to the Cartagen Knitter page (yes, that’s what I’m calling it) or posted here in comments.

Coming soon: a pen tool to trace out buildings from the images you upload.
