We have excavated a very large 5.000 year old fish fence, which was documented by photogrammetry, and is now being digitized. I started digitizing the orthophoto in QGIS and everything is cool. Now I've been ask to add Z-values to each of the corresponding polygons (pieces of wood). I then created a DEM of the model in Agisoft Photoscan Pro, and all the information is there.
Is there a way to to automatically transfer the Z-values from the DEM, to the overlaying polygon?
