Hi,<br>
<br>
This aerial image was made on March 8, 2016, in Odessa, Ukraine
(Moldavanka settlement). Altitude 150 meters, the wind at that day
was 6 m/s, gusts up to 8 m/s (28 km/h, 17 mph). The limit for
Phantom 3 [1] is 10 m/s. It is the full size image from Phantom 3
Advanced:<br>

<br>
<span style="white-space: nowrap;">This image size is 4,000×3,000
(4.82 MB), so I could zoom, count building:levels, and add them to
the OSM for quite a few buildings. <br>
<br>
The weather on this day was not perfect for aerial photography as
there was a strong wind with haze from the sea, still the images
came out sharp enough.<br>
<br>
I noticed that after adding the building:levels tag to a building
it is rendered at <a href="http://maps.me/en/home">maps.me</a>
application for smart-phone with the correct 3D height. <br>
A large number of such aerial images in all directions is produced
during one flight, so a large area is covered. <br>
One more advantage of the Phantom 3 is that the geographical
coordinates are added to the JPGs photos automatically and
precisely, <br>
as the aircraft has the GPS&GLONASS system and a compass.<br>
<br>
DJI Phantom 3 Advanced became more affordable, as DJI began to
sell the new Phantom 4 (which, by the way, has got even more
advanced camera and stabilization system).<br>
