The terrain follow feature available in the enterprise series of the Mavic 3 is a great way to adjust your mapping missions to the surrounding terrain, improving the quality of the output by ensuring a consistent field of view and ground sampling distance (GSD).
However, if you want to map at low levels you are going to need to use a DSM file. And if the maps from your area are out of date or not detailed enough, then you will need to create your own DSM.
Here's how to do that.
