Automated Ground Control Point Identification using Deep Learning Techniques [PDF]
VGC 2023 - Unveiling the dynamic Earth with digital methods : 5th Virtual Geoscience Conference ; Book of Abstracts, 2023 Ground Control Points (GCPs) play a crucial role in photogrammetry, providing essential information for georeferencing, registration and scaling of aerial and satellite imagery. These reference points, with known coordinates, are strategically placed and precisely measured on the ground to achieve accurate georeferencing in the photogrammetric process.
