[HOT] Surveying Helicopter Landing Zones (HLZs)

Hello Keith,

During the Nepal earthquake, the 'armchair mappers' where asked to draw
circles on the aerial images in openstreetmap with a given diameter,
visually selecting flat areas that where clear of buildings, trees and
rocks. I think this would be a combination of your 1 and 2.

3 would then not be uploading, but tagging the landing-zones with a certain
quality based upon ground truth (making 4 unecessary). This could be done
by people on site with a variety of (mobile/tablet) openstreetmap editors.

5 has been done in the Nepal situation already as far as I know.

In my opinion, HOT is an open community. You are free to conduct your study
and I hope you will be thrilled by the unlimited possibilities of the
openstreetmap data-model.

Good luck and have fun!
