DIGITAL ELEVATION PRODUCTS Aerometrex offers Digital Terrain Models (DTMs), Digital Surface Models (DSMs), and digitised 3D feature data for Geographic Information Systems. These can be generated through Imagery or LiDAR data. Large area digital elevation models help geologists analyse surface features and predict underground deposits during the exploration phase. Digital surface models are particularly useful for volumetric calculation such as stockpile estimation and change-detection over quarries. They can also help assess a mine’s resource extent and plan stripping operations to quantify development costs.
