Lets assume that I fly at the maximum allowable 400 ft allowed in class G Airspace, will I really get better results than at 200 ft? And if I could get clearance to fly at 1200ft, would the Mavic 2 Pro even see anything from up there?
I am completely new to DTM generation and topographical maps, so if I am missing something, I know it is my inexperience. It just seems that the recommendations I have found from Pix4D are confusing.
A Digital Terrain Model will try to generate the elevation model without the vegetation.
A Digital Surface Model, will generate the elevation model including the vegetation.
NADIR vs. Angled images:
As you have found there is no real truth on this topic, as the area you need to fly is not that big, you can try both nadir and oblique flights, have it compared and see what gives you better results. Personally I would go with Nadir and at least 85% overlap, front and side.
