摘要
通过计算在统一3°带下,边长投影到参考椭球面上,再投影到高斯平面上的长度变形值的大小,得出长度变形值超限,随后进行了在投影于抵偿高程面上高斯正形投影3°带的平面直角坐标系统的推算,并对计算结果进行了分析,最后选取了德州市平面控制网坐标系统。
Through calculating deformation value of side length projecting to referenced elliptical spherical surface and then projecting to Gaussian plane under uniform 3 degree belt, the following paper draws a conclusion of overrun of length deformation value, calculates horizontal rectangular ooordinate system of Gaussian oonformal projection 3 degree belt projecting to oompensation height plane, analyzes computing restilts, and finally selects ooordinate system of Dezhou horizontal oontrol network.
