Abstract :
Lidar has provided one new method for the digital elevation model (DEM). It has the advantage of gaining the three dimensional information, the wide measuring range, the high spatial and elevation resolution. What the lidar system gains is the cloud data, which can produce the digital surface model of the scanning area directly. However, if we want to withdraw the digit terrain model, still need to classify and process the cloud data. This article introduce how to use Lidar post-processing software such as POS software, the ALS40 post-processing software as well as the Terrasan module and the LPS module deal with the cloud data together, finally produce DEM in the ERDAS software.
