EFFICIENT WORKFLOW CHCNAV offers a complete solution for adding LiDAR surveying to users' geomatics services. Fully automated reality capture and real-time mission monitoring is provided by SmartGo software and intelligent point cloud processing by CoPre desktop software.
ENHANCED VEGETATION PENETRATION With its advanced multi-target capability, the AU20 supports up to 16 target echoes for superior vegetation penetration ability. Capturing ground surfaces and generating accurate Digital Elevation Models (DEMs) and Digital Surface Models (DSMs) is made easy, even in difficult environments with dense vegetation.
