Map of aerial obstructions - towers, antennas, etc.

[Ed Fink]

Where can I find a map or db of aerial obstructions (water towers, transmission towers, antennas, etc.)? Even cranes have to be registered with the FAA, so I’m sure all that is on a map somewhere. I remember shooting panoramas from a helicopter in Columbus, Ohio and the pilot’s GPS showed all the antennas, plus it flashed a warning and SHOUTED at us when we got too close.

I’ve Googled for hours without finding anything I can use. Wouldn’t this be something everyone should check before flying a quadcopter in a new location?

FCC publishes a database of masts but it is far from complete.

Why not a VFR 'sectional'?

You can find them here;
VFR Raster Charts

This is where GPS makers get their data:
Federal Aviation Administration

Get a VFR sectional. Made for pilots

Try a trial period on skydemon. Think it has the states info on it but I use it for the UK.

You can also download airspace info onto Google earth.

Best I could do was fly up to 150 ft do a 360 and id'ed the obstructions. Flew over to them and the check the altitude with my quad. I found that high tension power lines were at 125 ft. Some cell towers at 180 ft. So I have clear sailing at 200 ft. Worked for me.
