[HOT] Surveying Helicopter Landing Zones (HLZs)

Hi Denis
In the context of Humanitarian Responses, there are various situations were we have specific requests. We accepted for the Nepal response to spot eventual helicopter landing zones. We did setup a Skype room to discuss with people with experience with helicopters.  Often in the context of such emergencies, we dont necessarily have the contact with the persons that would use the data or any feedback.
But the interface with operationals in the field is essential. This is something we should improve. If organizations want to work with us to do such tasks, they should interface and assure we can progress rapidly with quality data.

For the Vanuatu response, I had the opportunity to share my screen from Skype with an airport controller to validate each landing field on the various islands. This was an efficient, rapid way to validate the data, and adjust if necessary. We could evaluate if this was a valid landing zone, evaluate the lenght of the runway and revise the tags.
If there are any interest to repeat such experiments, I agree, we need this type of discussion with organizations that actively fly helicopters & planes within the affected areas.
Private tasks could be setup to reserve the access to experienced contributors that have been trained to do such jobs.

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

@MAF & @MountainChild @KLL: It would be great to have your input on this topic.

Hi Keith,

I worked a lot on this issue during the Nepal 2015 response.

What you propose sounds great. We had a lot of difficulty trying to do
this via the tasking manager for several reasons.

I would love to speak with you more about it, maybe we could chat via skype.
