RIEGL, an unmanned, airborne, mobile and terrestrial laser scanning solutions firm, has provided a visual demonstration of one of its laser-based innovation in a bid to showcase what it is capable of.
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 ‘labyrinth’ cave with a total length of more than 40km 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 were provided with each measurement. Using the reflectance value, for example, allows surface material detection and e.g. visualization of all surfaces covered with ice.
