[HOT] Question on Nepal helicopter landing sites mapping

I have been mapping "aeroway=helipad" in the following way:
1. In JOSM, I draw a line 30m in diameter.
2. Then I use "Create Circle" and add "aeroway=helipad"
3. If it doesn't fit in the area where I drew the line, I use "Copy" and
delete the circle.
4. I then move accross the map seeking potential spots. Once I see one, I
press "Paste" to see if the 30m diameter circle fits. If it does, I leave
it there or move it slightly to fit. If it doesn't, I delete the circle.
5. I repeat this process across the entire area of the task.
6. I close the task and in the comments I tell how many helipads I have
drawn, how many are in the task and how many "leisure=common" squares are
in there and I ask "Please evaluate".
I would strongly suggest the evaluators to check the tasks with autorities,
checking with experienced pilots or commanders if the spot is a potential
candidate. But this process is out of my hands.
