This tutorial will walk you through the entire GCP process including definition, distribution, marking and measuring.
Ground Control Points (GCPs) are essential to produce accurate and reliable photogrammetry data. This is why, in most cases, we require our pilots to capture several GCPs.
Instead of writing pages and pages of articles, we decided to record a comprehensive tutorial series:
Part 1 – Definition and distribution
Part 2 – Planning GCP location in Google Earth PRO
Part 3 – Proper marking of GCPs
Part 4 – Measuring GCPs
Part 5 – What GCP specific factors impact drone mapping data accuracy
We hope that those videos are useful. Please make sure you watch it few times.
