A Multi-resolution Model of Curve for Progressive Transmission over the Internet

摘要：

　　Concerning the problems of high time complexity and topological inconsistency existed in vector map simplification,a multi-resolution model of curve for progressive transmission is proposed in this paper.By using pre-stored vertex deviation to simplify curve and using an optimized monotone chain intersection algorithm to maintain topological consistency,the model can quickly generate topologically consistent multi-resolution curve data.Finally,the model was used in the experiment of progressive transmission of river network and verified its effectiveness.
