I do work with Public Lab and have a fair amount of experience with the balloon mapping tools. I've not used PL tools to bring imagery into OSM, but my colleague at PL, Liz Barry, gave a talk on the topic at SOTM-US this year: http://vimeopro.com/openstreetmapus/state-of-the-map-us-2013/video/68100204
The Grassroots Mapping listserv might be a good place for questions: https://groups.google.com/forum/#!forum/grassrootsmapping (I'm, of course, happy to answer questions, but these folks have been at it longer than me and doubtlessly know more than I do.) Also, Stewart Long, one of the founders of Public Lab, is an aerial imagery wizard and probably knows a whole lot about this: http://publiclab.org/profile/gonzoearth Cheers, Jessi On Mon, Oct 28, 2013 at 11:21 AM, Nelson Minar <nel...@monkey.org> wrote: > Has anyone here used balloon mapping or these tools (or similar ones) who >> can share experience, pitfalls, etc.? >> > > Public Labs is terrific.
