Waveform Processing Airborne Laser Scanner for Wide Area Mapping and High Productivity • high laser pulse repetition rate up to 2 MHz • up to 1.33 million measurements/sec on the ground • excellent multiple target detection capability • excellent suppression of atmospheric clutter • Multiple-Time-Around (MTA) processing of up to 45 pulses simultaneously in the air • online waveform processing as well as smart and full waveform recording • parallel scan lines and uniform point distribution • interface for GNSS time synchronization • seamless integration and compatibility with other RIEGL ALS systems and software packages The RIEGL VQ-780II-S is a high performance, rugged, lightweight, and compact airborne mapping sensor. This versatile system is designed for high efficient data acquisition at low, mid, and high altitudes, covering a variety of different airborne laser scanning applications from high density to wide area mapping. The high speed rotating mirror design ensures reliability, and uniform point distribution across its entire wide field of view and at all flight altitudes. Based on RIEGL’s proven Waveform-LiDAR technology, the system provides point clouds with highest accuracy, excellent vertical target resolution, calibrated reflectance readings, and pulse shape deviation for unsurpassed information content on each single measurement. Excellent atmospheric clutter suppression yields clean point clouds with minimum efforts in filtering isolated noise points. The system is complimented with RIEGL‘s advanced acquisition and data processing software suite that utilizes parallel computing (GPU) for fast data processing. The RIEGL VQ-780II-S is designed to work with the latest Inertial Navigation (IMU) Systems, flight management systems, and camera options. Applications: • ide Area / High Altitude Mapping W • High Point Density Mapping • apping of Complex Urban M Environments • Glacier & Snowfield Mapping • City Modeling • Mapping of Lakesides & River Banks • Agriculture & Forestry • Corridor Mapping visit our website www.riegl.co
