  • It is important to compress and optimize the line features in the studying of the terrain environment simultaion,cartographic generalization and GIS.Based on the theory of wavelet analysis,the algorithm of Douglas and curvature analysis,the compression and optimization of the line features and the self-adaptive model are studied.The results of some experiments show that the proposed approach maintaines not only high compressing ratio but also the characteristics of the line features very well.
