摘    要:介绍的大比例尺地形图扫描数据处理系统LSMSS,是利用扫描仪将地图输入计算机,以图像处理技术,实现了从栅格数据到矢量数据格式,根据大比例尺地形图特点,利用已测坐标点,进行分块局部纠正的数字化方法,以提高数字化后图精度,并消 除地形图要素间的互位置的矛盾。

关 键 词:扫描数字化  几何校正  均匀化处理  地图  软件

Abstract:In this paper, a method for disitizing on the maps with a scanner is devel-oped. The algorithms of thinning, digitizing and automatic aimming are researched.According to characteristic of Large-Scale map, a digitizing method of partial correc-tion with coordinated point (control point or detail point) is discussed to raise the accu-racy of digitizing results and remove the contradictory of site in map element.
Keywords:Scanning digitizing  Geometric rectify  Even handling  Thinning
