Creation of 1:10 000-scale Digital Elevation Model

ZHONG Bin BAI Yu  
This paper, incorporating with practical production, discusses and analyzes the following issues concerning the creation of 1:10 000 Digital Elevation Models(DEMs), namely the sources, modeling methods, interpolation, quality control and accuracy evaluation. It concludes that the quality and efficiency of each DEM depends directly upon the selected sources, modeling methods, interpolation, data organizing and structures. However, to ensure DEM quality and boost its efficiency, an important way is to collect critical topographic features, like point and line when we collect contour or GRID to acquire DEM data from any kind of source.
