LIDAR Surface Elevation and Digital Elevation Map (DEM) of the CALIPSO LIDAR Data over Peninsular Malaysia

摘要

LIDAR backscatter signal analysis can establish surface elevation at the LIDAR footprint, in kilometers above local mean sea level. Since aberrations in the signal caused by a non-ideal transient response in the 532 nm detectors, the geometric thickness associated with the LIDAR surface elevation can be utmost misleading. In this place, the provisional LIDAR surface elevation should treated all signal beneath the reported LIDAR surface elevation top as being pure instrument artifact introduced by the non-ideal transient response of the detectors. Apparently, no geophysical significance should be ascribed to the subsurface portion of the LIDAR return. This study will present the comparison between the LIDAR Surface Elevation and Digital Elevation Map (DEM) using CALIPSO LIDAR data over Peninsular Malaysia.
