Description

Laserscanner  became an essential component for terrain monitoring in the past few years. With a maximum range of more than 2 km to naturally reflecting targets, a wide field-of-view, and a ranging accuracy of better than 2 cm, events like landslides or the movement of rock glaciers can be monitored reliably and accurately.

JOANNEUM RESEARCH has developed a fully automatic software environment to operate a laser scanner to primary monitor

• (rock) glacier
• snow covered slopes (avalanche risk evaluation and prediction)
• landslides

The system has been successfully operated at the Schwaz rock slide (Austria, summer 1999) and is annualy used for the monitoring of the Gößnitzkees glacier (since 2000) and the Pasterze glacier (since 2001) both are located at the Schober group in Austria.

In 2008 a new version of the Geoscanner software was introduced and is ready for deployment. The software integrates the fully automated generation of panoramas which are used to select regions of interest which will be scanned.
