Digital Terrain Models

Digital terrain modeling (DTM), also known as digital elevation modeling, is the process of preparing a continuous and detailed digital surface which represents the contour of actual ground within an area. These files are typically developed through the use of remote sensing data including LiDAR and 3D scans to create a digital representation of the terrain.

There are numerous applications for this technology including modeling water flow, soil and surface analysis, Geographic Information Systems (GIS), preliminary design and engineering, as well as the creation of 3D visualizations.

This process can also be completed through photogrammetry and convention survey techniques. Specific spot elevations and breaklines are captured to analyze the topography and provide the constraints to the surface model (DTM).

Various map scales and formats can be produced depending on the requirements of the project and Challenger will work with you to define those specifications.
