We successfully mapped Kifisos (Cephissus) area on behalf of the Institute for Water Education (IHE Delft) under the auspices of UNESCO using our DJI Phantom 4 Pro V2.0 plus a Near Infra Red (NIR) camera.
Here is a sample of RGB pictures (90 degrees down) taken on different days and areas which later were stitched together to produce orthomosaic maps.

Here is a sample of stitched photos to produce orthomosaic maps (about 1000 images for each map)
