Small Terrain Areas / DTM
When the terrain area is small and high-definition, such as an individual building
site, there are specialized fields with their own software and approaches for dealing with
this type of data.
"Digital Terrain Modeling" - DTM
- DTM is the name used for virtual terrain by
professionals in civil engineering, surveying and construction
- common tasks for this application of virtual terrain include:
- landscape planning, civil engineering, route planning, visual impact analysis, land surveying, sectioning, contouring, designing new surfaces or structures,
calculating volumes, and comparing surfaces level differences
- some academic groups studying terrain from this perspective:
- many DTM programs for working with elevation over small areas are listed on the
Elevation Contour Data page
