Solving the construction of regular surface feature symbols in surveying computer aided mapping system by the method of assignment

使用本文提出的任意多边形截幅方法不仅使DCS的图形处理功能更加完善，而且可改进采样方法，避免了地籍图上跨越界址线的地物符号可能出现的不合理现象。

By using the clipping method developed in this paper , the function of raph processing in DCS can be enhanced and the sampling procedure can be improved so as to avoid the unreasonable phenomena , which possibly exist when an object crosses the boundary line in cadastre maps .

本文利用AutoCAD软件丰富的二次开发功能，通过对CAD阴影充填基本方法的讨论，实现了在大比例尺地形图中按图示制图符号自动绘制面状地物充填符号。

By discussing of the basic mothod of CAD shadow filling , it is realized that drawing area filling symbol of object automatically by topographic map symbols in large scale topographic map with the rich second exploiting functions of AutoCAD .
