【摘要】 本文介绍了点值图自动编绘的方法和试验效果，描述了怎样根据不同的地形条件使用统计资料编绘点值图的途径。共分三部分：1．如何使用多边形软件系统来建立统计单元——地形类型界线的数据文件，该文件包括了在统计单元内划出不同地形类型分布范围的信息，为编制点值图提供了按统计单元及地形类型配置点群的基础；2．提出了在统计单元内按地形类型差异给予不同权值来计算制图指标值的方法，并论述了如何使用统计分析方法合理确定点权值以获得最佳效果；3．详细地给出了点位布置的算法以及讨论了图形输出的一些问题。作者最后指出点值图的自动编制涉及的问题较多，目前还需手工校正，但是随着软件和硬件的不断完善是可以获得完满解决的。更多还原

【Abstract】 :This paper introduces the method of compiling dot map automatically as well asthe results experimence. It also describes the way how to use statistic data to compilethis sort of map under different relief conditions.Three sections are given here. Sec. 1. how to use polygon software system to esta-blish the data files of the statistic units and the relief type borders. The data files inc-lude the information of different relief type distribution areas and the location of settingdots in units. Sec. 2. the method of calculating cartographic object value. Differentweights of relief types in a statistic unit are used in the calculation. Meanwhile, it isalso expounded here that how to difine dot weights retionally through the analyticalmethod of statistics in order to get the excellent results. Sec. 3.the algorithm of settingdots in an unit or area and the graphic output problem are described in detail. Finally,the authors point out that so many problems in compiling dot map automatically so farand it still need to modify by hand, but in the near future the problems should be solvedsatisfactorily after improving the software and hardware system.更多还原
