航路规划中数字地图综合处理技术

摘要

Based upon research of the medium-long range anti-ship missiles route program, this paper investigates the digital map application related disposing technology. First of all, we introduce the Digital Elevation Model and its disposing technology. Secondly, we discuss the basic principle of the grid division of the digital chart, then analyze the key factors which should be taken into account when calculate the MC (Map Cost) of each grid unit on the map. At last, we give the method to calculate the BC (Best Cost) according to MC, which builds up the foundation for the later realization of the route planning algorithms.%以中远程反舰导弹航路规划为背景,研究了数字地图应用的相关处理技术.首先介绍了数字高程模型及其相应的处理技术,其次论述了对数字海图进行网格划分的基本原则,然后分析了计算地图上每个网格单元的代价MC(Map Cost)所需考虑的主要因素,最后给出由MC生成的最小代价BC (Best Cost)的方法,为下一步航路规划算法的实现奠定了基础.
