I was looking to photograph a lake and river. As I checked on a map I saw a small airfield very close by. The GEO zones on the DJI Go4 app shows no limitations and B4UFLY shows no restrictions. The airfield is quite close though. It does not look like a good place to fly. What are the rules governing this location?
