DEM (Digital Elevation Model) describes elevation values across the map, excluding vegetation and man-made structures. It describes “bare earth” elevation. The result can be applied in survey, hydrology (calculate flow accumulation and flow direction), geology, construction, utilities, etc.
After the LiDAR data is obtained, the data can be post-processed only after data preprocessing. After the data preprocessing, there is a data checking software to conduct a preliminary check on the data results. The general data format check has the follo
Lidar (light detection and ranging) is an optical remote-sensing technique that uses laser light to densely sample the surface of the earth, producing highly accurate x,y,z measurements. Lidar, primarily used in airborne laser mapping applications, is eme
LIDAR (Light Detection and Ranging) technology and processing is used in a wide range of research and practical applications. With its ability to measure dimensions, distances, textures, and many other aspects of targeted subjects, LIDAR processing has be
