中文摘要：

兵棋是对作战过程进行逻辑推演研究和评估的重要工具,是现代作战模拟的一种重要方法和手段。兵棋的三大要素包括棋盘、棋子和规则,棋盘的经典样式就是六角格网兵棋棋盘,计算机兵棋中也常采用六角格网兵棋棋盘描述战场地形环境。推演过程中通常涉及到大量的坐标转换,因此坐标转换效率对于推演效率具有重要影响。针对经纬度坐标和六角格网编码的转换,提出了直接转换和间接转换两种坐标转换方法,分析了各自的基本转换原理,并给出了坐标转换公式,最后通过实验对两种方法的转换效率进行了分析,证实间接坐标转换法具有更高的转换效率。

英文摘要：

As a military science tool to research and evaluate the process of combat, wargame becomes an important method of combat simulation. Wargame has three elements, they are the warbame map, pieces and rules. The hex wargame map is the typical mode, and hex wargame map is often used to represent the battle field terrain environment by the computer wargame. A mass of coordinate transformation is used during the wargaming; therefore the efficiency of transformation has an important impact on the efficiency of wargaming. Two methods of coordinate transformation： direct transform and indirect transformare put forward, the basis transform theory is analysed, and presents the formulas of coordinate transformation. Finally, the efficiency of two methods of coordinate transformation is analyzed, the results of experiment are validated that the indirect transform bears higher efficiency.
