曲线弯曲多叉树模型及其在地图综合中的应用
Multi-branch tree model of bend for curve and its application in map generalization
摘要
Abstract
This paper researched the relation between bend multi-branch tree of curve and multi-scale map representation based on bends as a basic structure unit of curve, and proposed the model of multi-branch tree of bend for curve shape, which was based on bend binary tree, whose defects had been pointed out. Furthermore, it brought up a generalization strategy for curve multi-branch tree of bend. The experimental results that the model is used in contour simplification show the algorithm proves very effective in the aspects of holding the shape of line feature, geographic-feature consistency.关键词
