A workflow from drone photos to orthophotos, point clouds, DEM/DSM and basic terrain or vegetation analysis.
Check photo count, overlap, capture time, camera parameters and GPS information.
Insufficient forward and side overlap will noticeably degrade mapping quality.
Generate orthophotos, point clouds, DSM, DEM and 3D models.
Test parameters on a small area before processing the full dataset to avoid long failed runs.
Check orthophoto position, resolution, boundaries, holes and anomalous areas.
If you have ground control points, check horizontal and vertical accuracy.
Compute slope, aspect, elevation differences, canopy height or terrain indices from DEM/DSM.
The DSM–DEM difference can estimate canopy or object height, but watch the quality of ground points.
Export thematic maps, statistical tables and analysis results for reports or papers.
Drone imagery files are large; compress, tile or keep only the necessary outputs.
