【摘要】 MGIS(Military Geographic Information System,MGIS)符号是军事地理信息系统中最基本的构件之一,对其生成方法和控制策略进行研究是十分必要的。本文围绕MGIS符号的分类及其结构、生成方法和控制策略问题进行深入的分析、研究。论文首先从军事标图及MGIS符号的基础理论和研究现状出发,在已有的MGIS符号分类基础上,通过对各类符号构成特点的仔细分析,指出了规则MGIS符号的实质就是点状符号;并对其中的随机MGIS符号进行了再次细分,将其分为线状MGIS符号,面状MGIS符号和态势符号,为后续的系统实现打下了基础。论文接着分析了各类符号的自身特点,提出了对规则MGIS符号采用图元法,对随机MGIS符号采取程序法的实现策略。提出了基于曲线长度、重心及几何参数分别实现线状、面状、箭头类符号的方法,该方法方便实用,易于实现。论文在MGIS符号的生成基础上进一步研究了其控制策略问题,给出了MGIS符号定位点的确定方法。文章对于随机MGIS符号的各自特殊的调整变换方式给出了详细的控制策略,通过较少的控制点完成了对箭头类MGIS符号的控制。论文最后实现了电磁态势标绘系统,系统综合应用了MGIS符号的生成与控制方法。该系统已在某军事部门实现装备,获得良好的军事效益。更多还原

【Abstract】 Military Geographic Information System symbol is the base component of the MGIS, it’s necessary to research the method of the MGIS symbol producing and controlling. A deep analysis and design have been done on the structure of MGIS symbol and the method of MGIS symbol’s producing and controlling.First of all,this paper points out the essential of the regularized MGIS symbol is the punctual symbol which based on the theory of map symbol and the researching actuality. Based on existent MGIS symbol classification,this paper classified the random MGIS symbol into three parts.One is the line style MGIS symbol,second is the area style MGIS symbol,third is the state MGIS symbol.All of these do good for continuing research.By analyzing the characteristics of each MGIS symbol, this paper used the Meta method to realize the regulat MGIS symbol.It used the method of programming to realize the random MGIS symbol.Facing to the line style MGIS symbol,the area style MGIS symbol and the arrow symbol,it uses the method of curve draw up and the method of barycenter and the method of geometrical parameter to realize them. The method is practical and easy.After the MGIS symbol is produced,the paper researched how to control it. This paper points out that the key of realizing normal transformation for MGIS symbol is to find its anchor points. And then it gives some method to confirm MGIS symbol’s anchor point.This paper give the controlling method of all kinds of random MGIS symbols at large by their especial change and that uses less reference point to control the arrow symbol.At last,this paper illuminates the Electromagnetism State Marking System that bases on the MGIS symbol’s controlling and producing method. This system has been equipped in certain military department to get better military benifient.更多还原
