平面控制点

也谈平面控制点的相对点位精度问题

On the Relative Positional Error of Horizontal Control Point

由1：10万地形图选取平面控制点对TM磁带进行精处理，平面定位精度为半个象元，精度较高；

When the precise geometric rectification of TM imagery was made with the ground control points selected from topographic map in scale of1:100000 , the accuracy of half a pixel is high .

通过由平面将控制点移动到设计给定的几何位置，寻求了一个与给定预应力值分布及结构几何控制参数相对应的平衡的形状，建立了一种悬索结构的初始形状确定分析方法。

The control points are moved from a plane to the given geometric position , and then the form balancing the given prestress distribution and the geometric control parameters of the structure is found . In this way an initial form-finding ; analysis of the cable structure is developed .
