| Abstract: | This paper introduces the DEM NSDTF-DEM format and ArcGIS Grid format code, the latter DEM format has wide appli-cation and support for their reading and processing of more GIS software, so this paper by program of the former to the latter conver-sion.DEM quality inspection and evaluation of precision is an important reference for the construction of the standardization of the na-tional fundamental geographic information, this paper describes in detail the various DEM quality inspection method based on Map-GIS,and the DEM accuracy was evaluated , so as to grasp the product quality as the4 D DEM provides the guiding method. |
