Geometric Accuracy Assessment of Linear Features' Simplification Algorithms

Abstract

On the basis of analyzing the influence that linear features' accuracy by simplification algorithms can be divided into geometric accuracy and attribute accuracy,aiming at curves' characteristics on geometric character and position of points change in the process of simplification,considering all the change of linear features' accuracy,position accuracy is the most important and quantitative easily,a series of evaluating figures of geometric accuracy are proposed.Several typical simplification algorithms are evaluated and some credible conclusions are given.
