基于三角网构建海底DEM的抽稀算法
A Method for Data Thinning Based on the Topology of Triangulation Irregular Net to Construct Submarine DEM
摘要
Abstract
For compressing a large number of depth data to present submarine DEM quickly, inextenso and accurately, a new method for data thinning based on the topology for triangulation irregular net is brought forward. The advantage of D-Tin is used to search the area related with the depth points and then their significance are analyzed based on their contributions. The experiment indicates that this method, being of high speed, high accuracy and low distortion, can adequately recognize the variety of landform and identify the characteristic spot.关键词
