Services: DTM/DEM Surface Generation

Digital Terrain Modeling
Digital Terrain Modeling (DTM) is the collection of mass points of elevations and 3D breaklines at each change of terrain using Summit Evolution softcopy workstations.

The mass points are collected at a grid spacing that meets project requirements. A Digital Terrain Model represents the terrain accurately enough to generate contours that meet National Map Accuracy Standards (NMAS).

Digital Elevation Models
Digital Elevation Models (DEM) are one type of DTM format used to develop the three-dimensional rendering of a surface or analyze the terrain in various ways. The data can be collected manually or automatically on the Summit Evolution softcopy workstations equipped with INPHO’S Match-T automated terrain extraction software.
