Very interesting. Thank you. I did not even know about these projects. I 
will definitely use these 3D maps.

However, even on these 3D maps there is no icon for the communication 
tower. The (man_made=tower; tower:type=communication) is of interest to 
the unmanned aviation not only because of the height, i.e. a risk of a 
collision, but mostly because its strong electro-magnetic emissions in 
some cases may interfere with the remote control signal and the 
navigation system (on-board magnetic compass). It is not difficult to 
avoid them knowing where they are.

The UAV cargo delivery technology is mostly of interest to Africa [1], 
where ground roads in rural areas are often unreliable in a rainy 
season. But even in modern urban centers, delivering say paper documents 
between banks by air may free roads from hurrying couriers and by this 
make traffic safer.

Fortunately, other related tags: power-lines, wind generators, 
lighthouses, are already well rendered with an icon on the OSM map.
