Waveform Processing Airborne LiDAR Scanning System for High Point Density Mapping and Ultra-Wide Area Mapping

The VQ-1260 is one of RIEGL‘s latest high-end airborne laser scanning systems, suitable for a wide field of applications – from high-point density wide area mapping to ultra-high resolution city mapping or corridor mapping.


The unique design features pulse repetition rates from 2.2 MHz, resulting in a regular point spacing and an almost constant point density distribution on the ground. The system features large measurement distances of up to 2300 m at maximum PRR, and 5400 m at minimum PRR, for a target reflectance of 20 %, resulting in an unsurpassed high efficiency in area acquisition of e.g. up to 500 km²/h at 150 knots flying speed for an average of 8 points per square meter.

A newly designed optical frontend significantly minimizes for near-range echoes due to atmospheric clutter, resulting in clean point clouds. Online-Waveform processing and full-waveform processing capabilities are a matter of course for this class of equipment.

Scan data and camera images are stored on removable hard disks that can be accessed directly on the device, eliminating the need for an external data recorder.

A high-performance IMU/GNSS unit and one or two optional high- resolution RGB/NIR cameras are seamlessly integrated in the compact and user-friendly designed housing. The standardized mounting flange fits typical hatches or gyro-stabilized leveling mounts for maintaining optimum point distribution.
