[OSM-talk] Mapping Klong Toey Slums

[Oleksiy Muzalyev]

Power poles, wires, wind, trees are usual dangers for multirotor 
aircraft too. There is also an issue of a large bird attack. These risks 
could be mitigated via sport flying.

I usually train sport flying at a stadium very early in the morning when 
there no people there. I have got a small trainer quadcopter, several 
foldable Air Gates, and Air Flags. There are also gates at an American 
football field with high poles, which are good for learning to fly in 
narrow spaces.

I have an impression that birds being excellent fliers themselves can 
immediately see the level of piloting skills of a RPAS (Remotely Piloted 
Aircraft System) pilot. If they see that it is an friendly experienced 
pilot they usually do not attack. In any case I regularly train diving 
and other BFM <https://en.wikipedia.org/wiki/Basic_fighter_maneuvers> .

In addition to aerial images I also film aerial video. Video provides an 
additional information. For example, recently I filmed a medieval 
Bilhorod-Dnistrovskyi fortress [1] in Ukraine. I upload a video to 
Wikimedia, add a video link to the Wikidata page, and add wikidata tag 
to the OSM map for this object.

Wikimedia accepts videos only in open OGG and WEBM formats. 
Unfortunately, some quality is always lost during conversion to these 
formats. You can see the same HD video at youtube and compare the 
quality [2]; I tried all convertors which I could find for Mac.
