Study on the Software of Large-Scale MapDigitizing Based on Scanned Images

Hua Xianghong Pan Zhengfeng (Wuhan Technical University of Surveying and Mapping, Wuhan, 430070)  
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.
