method of coordinate geometry

The results showed that using universal coordinate transform program and analytic geometry method could resolve the problem of measuring area for GPS without function of measuring area.

结果表明，利用通用坐标转换程序，结合解析法求算面积的方法是解决无测积功能GPS测量面积的理想方法。

The Computer Aided Quality Inspection method of combining the coordinate measuring machine (CMM) and 2-d CAD geometry information extracted from DXF is illustrated by an example.

以一支座为实例介绍了一种利用三坐标测量仪与从二维工程图的DXF文件中提取的CAD几何信息相结合实现计算机辅助产品质量检测的方法。

In the paper, the authors present the common law of structural topology and geometry and the method of abstract, and give the integer nominal coordinate system.
