Using WebODM to Process Drone Imagery (RTK or GCP) & Perform an Accuracy Assessment with QGis Part 2

This is part 2 of WebODM adventure! Time to do the accuracy assessment. Outline: 1. Add surface model, orthophoto, and ground surveying points to QGis 2. Separate the GCPs from the ground surveying points 3. Sample the DSM at the GCP points 4. Calculate the bias correction 5. Removing stray points near the edge effects 6. Apply the bias correction 7. Calculate the RMSE
