Lidar system for mapping complex terrain

February 12th, 2018, Published in Articles: PositionIT

TerrainMapper is Leica Geosystems’ next generation linear mode lidar system. As part of the RealTerrain airborne lidar mapping solution, the sensor is supported by the HxMap unified multi-sensor post-processing workflow. The mapping solution enables users to increase point accuracy, deliver even point density across the swath, and accommodates more efficient flight planning in complex terrain such as urban spaces and mountainous areas. The TerrainMapper increases data collection efficiency up to 2 MHz measurement rate while operating with gateless Multiple Pulses in the Air (MPiA). Flying heights of 300 to 5000 m and adjustable field of view gives users the flexibility to fly higher for larger swath width or lower for ultra-high point density. A built-in camera collects information for point cloud colourisation with co-registered 3 or 4-band options. The system also delivers United States Geological Survey (USCS) Quality Level 0 data at up to 500 km2 per hour collection rates. The 5 cm accuracy, even at higher flying heights, offers an efficiency improvement for complex and changing terrain.
