Digital Terrain Models
Volumetric survey data collected in the field can be processed to form a 3D Digital Terrain Model (DTM). The resulting DTM can form the basis for volume calculations, surface area measurements, contours and cross sections.
The data contained in the computer generated Digital Terrain Model is extensive and eliminates the need for difficult and laborious calculations, previously done by hand.
Determining accurate volumetric quantities may be required for a variety of purposes including:
- Quantifying crushed or excavated materials.
- Cut and fill exercises to balance earthworks for building and civil engineering projects.
- Tendering for construction projects.
