Spatial Relationship and its Algorithm in Hexagonal Grid Coordinate System
摘要
Abstract
Spatial relationship is the basis of spatial data s organization query analysis and reasoning. Hexagon is composed of three basic primitive types vertex edge and face. Since wargame map used hexagon to implement the quantization of battlefield environment information battlefield environment entity s spatial relationship is shown as basic primitives spatial relationship. Common hexagonal grid coordinate systems was summarized. In terms of bas-ic primitives average count the coordinate encode was designed which made the mathematical foundation for the resolution of data redundancy and the implementation of spatial relationship algorithm. The spatial relationship be-tween primitives and its algorithm was described in three aspects which included topological relationship orienta-tion relationship and measure relationship.关键词
