Environmental research with active sensors (ActiveSensing)

The research group of Environmental research with active sensors.

The research group of Environmental research with active sensors, i.e. ActiveSensing-group, is a mix of remote sensing experts in the field of physics, mapping, environmental research and measurement techniques equipped with versatile tools for research, e.g., terrestrial laser scanners, supercontinuum laser, close-range laser profiler and a laboratory for laser intensity calibration. The major aim is to develop and demonstrate new applications of active sensing methods, such as laser scanning and SAR, in environmental remote sensing. The research topics include laser scanning for forest carbon cycle estimation, snow cover monitoring with mobile and terrestrial laser scanning, development of hyperspectral lidar (and its environmental applications), applying SAR and radar-lidar synergy in environmental remote sensing, and the radiometric calibration concept for laser scanning.
