摘要
对清华山维的Epsw2005全息测绘系统中等高线内插法的应用进行了深入研究。该方法相对于软件自动生成等高线具有等高线走向合理、曲线平滑、修改量小的优点。
In the application of contour interpolation in the Epsw2005 holographic mapping system of Qinghua Shanwei is to solve such problems: in Digital Mapping , the software automatically generates contour underwater has poor rationality and it has a large amount of contour lines change editing. Through the Three Gorges Reservoir tributaries topographic survey, the practical application of the method confirmed contour mapping interpolation method had high precision, fast operational efficiency and a small amount of contour lines editing and other prominent features.
