I recently had an internal request to capture and store the Bing imagery for an area for future use. The user was interested in some specific images that were taken after a fire, making the ground surface-and certain geological features-much more visible. His concern was that in the future this imagery might get replaced with updated imagery taken when the vegetation has grown back. Since it is unknown when/how this data might be used by us, we mostly wanted to capture it now & find a way to use it.
