Digital Terrain, Elevation and Surface Models


Aerial laser scanning is the only surveying method that can provide sufficiently dense elevation data of forested terrain, mapping with high accuracy (i.e. multiple points per square meter) the ground beneath forests. High-resolution terrain (Digital Terrain Model) and surface (Digital Surface Model) models are created by applying class filtering to return pulses and are available with regard to customers’ exact specifications. Digital models of terrain surfaces and object surfaces (e.g. bare earth, city models, vegetation models) can be provided in different grid sizes for a large variety of applications.
