Research on Methods of Automatic Drawing Depth Contour with Discrete Data Points
摘要
Abstract
We use multibeam discrete data points to construct grid DEM with the method of inverse distance interpolation. Then, we draw nonuniform relatively smooth DEM automatically under the chart production standard. At the end of this paper,we compare the contour which is drawn automatically with what is made by the general software and by the results of the undersea topographic map and analyse it, which comes to a conclusion that the depth contour which is drawn in this paper is greatly improved and can greatly accord with terrain than before. It can be used as the reference line for manual drawing.关键词
