Strange question. When it comes to AGL maximums in areas with mountains or large hills, I'm assuming the drone's zero foot measurement is from the launch point correct? I brought my MA2 out to my cabin which is a few miles outside the Great Smoky Mountains boundary. The cabin is few hundred feet above and about 1/4 away from the main drag of Pigeon Forge, TN. As I was flying around, I had a thought. If I hypothetically flew down to the street level and landed, would I now be restricted to 400ft from that AGL after re-launch or my original launch point at the cabin?
