摘要：This article will discuss a technique to convert raw or filtered laserscan-data to rasterized terrain or elevation models, by using ESRI's ArcGIS and Python. This programming language is supported since ArcGIS 9 and makes it possible to use the ArcGIS 'geo- processor' (Rodman & Jackson, 2006). For these digital terrain models, filtered airborne laserscanning-data (ALS-data) are used, processed with automated tools from the 3D Analyst Tools. These tools will be programmed in such a way, a minimum intervention of the user is required. This procedure may look very comprehensive, but accessible as well. This is done to make it as transparent as possible and to allow only the direct ESRI's ArcGIS tools to be black boxes. The proposed procedure itself will make it possible to gain the scientist full control on the process, by using regular software and without thorough knowledge of programming. Executing the proposed procedure will result in a set of separate TIN's, rasters, and a mosaic of rasters
