Digital terrain and surface models

Digital terrain models and digital surface models are created by TRIGIS according to strict accuracy requirements.

Production is fully and partially automated.

A digital terrain model (DTM) uses a dot matrix to describe the terrain surface. The position and elevation of each dot are known.

A digital surface model (DSM) describes the Earth’s surface, vegetation and building development using three-dimensional coordinates of ground and non-ground points. It is generated using echo points of airborne laser scanning.

The digital models are used in the following areas:

  • Agriculture and forest management
  • Disaster control
  • Archaeology
  • Noise control
  • Environmental protection
  • Radio network planning
  • Flood control


In cooperation with GeoFly GmbH, TRIGIS offers:

  • Contour maps
  • Slope maps
  • Line-of-greatest-slope vectors
  • Perspectives
  • Visibility maps
  • Cross-sections
  • Erosion risk maps
  • Volume determination
  • Shading

Municipal base maps

TRIGIS has over 20 years’ worth of expertise in the creation of municipal base maps.

A municipal base map contains all elements of the land register map, as well as comprehensive and detailed topographical components. This structured topography is standardized and describes routes, slopes, detailed representations of trees, street furniture such as lampposts, manhole covers, transformer stations, and much more. 


  • Planning tasks
  • Economy
  • Municipal authorities (planning permissions, zoning maps)



In cooperation with GeoFly GmbH, TRIGIS offers:

  • Aerial photography flights
  • Creation of city base map
  • Thematic maps and analyses (vegetation analyses, route analyses, etc.)

Real-use mapping (monitoring of residential areas)

Real-use mapping was developed in cooperation with municipal administration as a combination of base map analysis and GIS analysis (monitoring of residential areas).

The data base is provided by an aerial image interpretation using additional relevant data.

Automated algorithms developed by TRIGIS allow the detection and customized evaluation of changes in the area.


  • Base maps on area use
  • Collection of relevant data
  • GIS evaluation
  • Constant updating of base data

Solar capacity analyses

The cost effectiveness of solar installations depends crucially on the choice of site!
