[HOT] Surveying Helicopter Landing Zones (HLZs)

During the Nepal earthquake relief effort, mapping HLZs (Helicopter Landing
Zones) did not seem very coordinated, many factors need to be taken into
consideration to properly define a HLZ. I can confirm that very little of
the OpenStreetMap HLZ data was not used for any mission planning by any
NGO, Government or UN aid during my time in Nepal.

However, it would be great to open this type of discussion with
organizations that actively fly helicopters & planes within these affected
areas. Most of these organizations already have a their own HLZ data with
tons of precise attributes associated with the particular HLZ & terrain

Before any mapping happens, we should properly define a HLZ OSM Wiki page
to clearly define how to map an HLZ.
