Question

Accepted Answer

1. Flight planning

applying for authorisations
precise planning of the flight route using software or app
observing the weather report

2. Calibration

Lay out and measure control points

3. Flying

usually using automatic flight mode to take regular images with sufficient overlap
Checking the sharpness of the images and the recognisability of the control points

4. Processing the images with photogrammetry

Images are loaded into the software with GPS data
graphical calculations generate a 3D model
improve accuracy using control point data
The result is a point cloud that can be used for any purpose

5. Export the results

Create an orthophoto, measure the 3D model or determine the volume
