Accuracy of the LiDAR-derived DEM in dense shrub areas in mountainous NW US

Abstract

Digital elevation model (DEM) is one of the most important information that can be derived from the airborne LiDAR data. However in areas covered by dense vegetation, the chance of laser passing through the canopy, hitting the ground and back to the receiver is limited, thus it is difficult to achieve accurate DEM in regions with dense vegetative covers… (More)
