The RIEGL VQ-840-G is a compact and lightweight laser scanner for combined bathymetric and topographic surveying. The system is offered with an optionally integrated and factory-calibrated GNSS/IMU system and can be complemented with an optional camera or IR rangefinder. The VQ-840-G can be installed on various platforms including UAVs.

A visible green laser provides water penetration for high-resolution surveying of underwater topography and measurement of submerged targets. A measurement rate of up to 200 kHz and high scanning speed of up to 100 scans/sec provides superior spatial resolution, and the system offers concurrent full waveform storage of all measurements for subsequent analysis.

The VQ-840-G is ideal for a wide range of applications, including coastline and shallow water mapping, surveying for hydraulic engineering, and hydro-archaeological surveys.
