I have drone imagery which was generated in Agisoft. From the imagery a DEM was generated and exported.
I would like to know how do I get the Digital Terrain Model from this DEM? as I currently have the Digital Surface Model?
The method I have tried doing was creating points at different locations in between the trees(on the ground) and interpolating the points to create a DTM by subtracting the DSM and DTM (DSM-DTM= tree height) from each other.
However the results are not consistent enough to achieve tree heights accurately.
I do have ArcGIS Pro.
