An Area of Land in 3D

On a visual level, a digital terrain model is a 3D representation of an area of land. It consists of a simplified image that shows the ground altimetry and is formed with cells, pixels and dots that are linked together irregularly, forming a triangular or rectangular mesh.

A digital plan makes it easy to visualize a terrain’s topography and is helpful when calculating slopes, sections, curves and elevations. A digital terrain model does not take into account elements above the ground such as trees and buildings.
