在换带计算时控制点坐标处理分析探讨

INVESTIGATION AND ANALYSIS ON PROCESSING THE COORDINATES OF CONTROL POINTS WHILE CHANGING STRIPS

在投影带边缘测图边长变形过大，以致精度较低。采用转换１．５°投影带的投影方法，减小了变形，满足了测量精度的要求。

The deformation of length of measured plot along edges in projective area is too large. It results in lower precision. In order to meet the precision requirement, a rational projective method of changing 1.5 ° projective area is adopted to decrease the deformation and to increase its precision.
