I've been looking around and haven't seen this feature out there yet, but I could have missed it. is there a software (DJI GO, Litchi, Autopilot, Other) out there that you can set no flight zones? An example, if you wanted to fly in a park let's say at 30 ft, but you know don't want to hit a light pole. An idea I have is to place a virtual orange cone around that area and it won't let you fly into it. The obvious answer is, just avoid the pole or fly higher than the max height of the pole. Anyway just a question.
