Drone survey of a field and a detached house.

A DJI Phantom3 has been used for the survey, georeferenced with GCPs acquired with the Total Station (TS).

358 pictures were used for generating the Digital Terrain Model (DTM), a pointcloud made up of 73M elements. Mean error on control points is about 3cm.

The DTM has been used to automatically extract contours and the elevations grid.
