High-Accuracy Digital Terrain Models (DTMs) from Drone and Aerial Data
Using custom drone surveys with high-speed camera payloads and RTK/PPK systems, we generate Digital Terrain Models (DTMs) with accuracies of ~3 cm (X,Y) and ~5 cm (Z). Ground control check points further validate results while minimizing costs. This method offers significantly better accuracy than traditional aerial stereo collections, which typically achieve up to 15 cm precision depending on terrain and control point availability.
