Using the latest generation of airborne laser scanners, we acquire highly accurate and high-resolution point clouds of the earth's surface. The georeferencing and classification of these laser point clouds provides detailed representations of the earth's surface in the form of digital terrain models or surface models. These models serve as the basis for numerous planning tasks (e.g. spatial planning, infrastructure etc.).

By repeatedly mapping a region at different times, difference models can also be derived and used for change analyses.
