Underground Cave Scanning Using the RIEGL VZ-400i Terrestrial Laser Scanner!

We have a new video up on the RIEGL YouTube featuring the VZ-400i ultra high performance 3D laser scanner and its outstanding qualities of capturing underground data for large areas!


To showcase the outstanding qualities of the RIEGL VZ-400i for underground data acquisition of large areas, a special 3D laser scanning project was executed in the summer of 2017.

Data of the famous Eisriesenwelt, a cave labyrinth with a total length of more than 40 kilometers in Werfen, Austria, was captured in 370 scan positions within two days.

Only four hours were necessary for registration and post processing of the data. Based on RIEGL‘s Waveform-LiDAR technology, additional scan data attributes are provided with each measurement. Using the reflectance value -for example- allows surface material detection and e.g. visualization of all surfaces covered with ice.
