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

The VQ-1560 II-S follows the successful concept of RIEGL’s proven dual channel laser scanner series. With increased laser power the operational altitudes are extended up to 1700m AGL at a pulse repetition rate of 4MHz, or up to 3900m AGL at a pulse repetition rate of 540kHz (all values given for 20% target reflectance). These improved maximum ranges allow an increase of the system’s productivity by about 25% for a very attractive point density range.


Its unique "cross-fire" scan pattern and its wide operational range make the instrument the most versatile airborne laser scanner on the market today. It is perfectly suited for any kind of application – from ultra-dense corridor mapping from low altitudes, over high-resolution city mapping with minimum shadowing effects in narrow street canyons, to large-scale wide-area mapping at utmost efficiency of up to 1130km² per hour at a density of 4 points per square meter.

The system is equipped with a seamlessly integrated high-performance IMU/GNSS unit and e.g. an optional 150-megapixel RGB camera integrated into the primary camera bay.
Optionally, a second camera, e.g. a thermal camera or a 150 megapixels near-infrared camera, can be integrated on request. The design of the compact housing features a mounting flange for interfacing with typical hatches or gyro-stabilized levelling mounts.
