Accurate photogrammetry doesn’t start at the computer; it starts on the ground.
Proper Ground Control Point (GCP) planning is the foundation of reliable survey data.
Well-placed, evenly distributed GCPs sharpen spatial accuracy, minimize distortion, and anchor your 3D models to real world coordinates. Strong triangulation and disciplined placement practices prevent common errors that can compromise entire projects.
From drone mapping and topographic surveys to mining operations and construction monitoring, mastering GCP best practices is what turns aerial data into actionable geospatial intelligence.
