摘要
本文讨论了一种较有效的细化等高线扫描影像数据的方法——边缘剥皮法,利用该方法对等高线扫描影像数据进行细化,在微机上进行了试验,结果令人满意。
On setting up DEM with the contour raster data from the topographic map, thinning of the contour raster data is very important. There are many methods of thinning. On the base of absorbing the advantase of the methods, this paper discusses an efficient marginal thinning method and its practical use in the contour raster data with a microcomputer.
