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. Good luck! 2015-05-03 15:25 GMT+02:00 Michael <[email protected]>: > Hi, > > I think we might need some clarification on how to map the helicopter > landing sites (Projects #1023 and #1026). > > What I did is this: > - for an official helipad I would create a circle and tag it with > "aeroway=helipad" - but I have not come across one while mapping. > - if it is a potential landing site I create a polygon with the actual > shape of the site and tag it with "leisure=common" > > Recently I have seen other mappers doing thing a bit differently.
