i was in san francisco at FOSS4G in March and there was a LOT of talk about
opendronemap and the tools developed under open source to create good
quality georeferenced imagery. thecost of drones has plummeted in the last
couple of years and is now available in large quantitities to mainstream
users. It strikes me this could make a big difference even in the search
and rescue phases with quick turnaround of imagery on the ground straight
to TMS servers. The issue will be locating suitable quantities, processing
and creating the right targeted jobs to use it effectively - I think the
technology is pretty much there.
