Dual Channel Waveform Processing Airborne LiDAR Scanning System for High-Point Density and Ultra-Wide Area Mapping RIEGL VQ-1560i • high laser pulse repetition rate up to 2 MHz • up to 1.33 million measurements per second on the ground • offers data acquisition at a wide range of point densities • two waveform processing LiDAR channels offering excellent multiple target detection capability • enables Multiple-Time-Around (MTA) processing of up to 25 pulses simultaneously in the air • excellent suppression of atmospheric clutter • offers online waveform processing as well as smart and full waveform recording • integrated inertial measurement unit and GNSS receiver • integrated, easily accessible medium format camera • prepared for integration of a secondary camera • high-speed fiber data interface to RIEGL data recorder • housing shape and mounting flange optimized for interfacing with typical nd stabil stab stabil hatches and stabilized platforms le andgrips or le handgrips for • detachable handgrips for d handling handling dling i facilitated handling visit our website t www.riegl.com om Airborne Laser Scanning The ultra-high performance, fully integrated and calibrated Dual Channel Airborne Mapping System RIEGL VQ-1560i makes use of RIEGL‘s sophisticated Waveform-LiDAR technology enabling an excellent multiple-target detection capability and Multiple-Time-Around (MTA) processing. The system is capable of online waveform processing as well as full or smart waveform recording, resulting in unsurpassed information content on each single target. The VQ-1560i provides a laser pulse repetition rate of up to 2 MHz resulting in more than 1.3 million measurements per second on the ground and operates at an altitude of up to 18,300 ft. That allows operation at varying flight altitudes resulting in a wide range of point densities. Thus, the system is ideally suited for aerial survey of ultrawide areas as well as of complex urban environments. By the way, faster and more efficient flight planning and safer flights are enabled. The RIEGL VQ-1560i comes with a unique forward/backward scan angle. This enables capturing data from multiple angles more effectively and more accurately at a high point density. With its large field of view of 58 degrees and its widely variable scan parameters the system enables highly efficient scan data acquisition. The system is equipped with a seamlessly integrated high performance IMU/GNSS unit and an optional 100 megapixel RGB camera as well as another camera, e.g. a thermal camera or a 100 megapixels near-infrared camera. All individual components are integrated into a compact housing, featuring a mounting flange for interfacing typical hatches or gyro-stabilized leveling mounts. Applications: • Ultra Wide Area / High Altitude Mapping • High Point Density Mapping • Mapping of Complex Urban Environments • Glacier & Snowfield Mapping • City Modeling • Mapping of Lakesides & River Banks • Ag
