Waveform Processing Airborne LiDAR Scanning System for High Point Density Mapping and Ultra-Wide Area Mapping • high pulse repetition rates of up to 4.4 MHz • up to 2.93 million measurements per second on the ground • best point distribution for optimum target resolution • excellent atmospheric clutter suppression • multiple target capability • online waveform processing and full waveform data recording • on-board graphical user interface for easy access to primary scanner parameters • integrated inertial measurement unit and GNSS receiver • prepared for the integration of up to two high resolution RGB/NIR cameras • optimized for interfacing with typical hatches and stabilized platforms • deteachable handgrips for facilitated handling The VQ-1460 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 4.4 MHz, resulting in a regular point spacing and an almost constant point density distribution on the ground. For a target reflectance of 20 %, the system features large measurement distances of up to 5400 m at a minimum PRR of 540 kHz and of up to 2300 m at a maximum PRR of 4.4 MHz, resulting in an unsurpassed high efficiency in area acquisition of e.g., up to 615 km²/h at 150 knots flying speed for an average of 8 points per square meter. A newly designed optical fronted 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 highresolution 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. Applications: • Ultra Wide Area / High Altitude Mapping • Ultra-High Point Density Mapping • Mapping of Complex Urban Environments • Glacier & Snowfield Mapping • City Modeling • Mapping of Lakesides & River Banks • Agriculture & Forestry • Corridor Mapping visit our website www.riegl

RIEGL VQ®-1460 Dense Scan Pattern and Wide Effective Swath Width The RIEGL VQ-1460 scanning mechanism – based on a continuously rotating polygon mirror wheel – delivers straight parallel scan lines resulting in a regular point pattern on the ground. With equal spatial sampling frequency along and across track, object extents are well defined and even small objects may be detected. The instrument is perfectly suited for applications where a superior point pattern on target surfaces is required.
