Stereo plotting

3D surveying by aerial images

Aerial images are used for manual or automatic plotting. The measurments are fast and precise, reducing the need for expensive terrestrial surveys. 

Manual plotting is done by our experienced operators in stereo on a digital photogrammetric workstation. The resulting CAD or GIS data sets are the basis for many deduced products. Plotting contents and styles are tailored to the task at hand. Topographic databases and cartographic projects are characterized by high complexity. 

Stereo plotting

Automatic processing is based on dense image matching and yields very detailed 3D point clouds. These can be transformed into DSMs or DTMs by (semi-) automatic classification.
