after the crisismapping discussion yesterday, what think ye of at the very least compiling existing sources (as in the OAM wiki) but with a bit more structure as well as with resolution, license, date of capture, formats available, etc? Something like the following:
http://grassrootsmapping.org/imagery/ We could even measure performance (latency) and so forth to determine whether putting up a proxy in front of the official source would be a good idea. Also, here's the link to the 1999 survey of existing sources graphed by temporal vs spatial resolution which I mentioned at the meeting: http://www.asprs.org/publications/pers/99journal/may/1999_may_611-622.pdf That also has a table indicating minimum temporal, spatial, and spectral resolutions suitable for identifying a variety of data, from road widths to quality of life indicators, to post-emergency damage.
