| 摘 要： | 根据各种测图比例尺对控制网提出的不同精度要求,结合测区所处的地理位置,以及工程放样的特殊要求,应合理选择投影带和投影面,使工程平面控制网控制点之间的反算边长与实地量测边长基本一致,即投影改正误差不超过规范要求。

| Abstract: | Because of the geographical position of mapping,the special requirements of lay-out,and the different precision requirements of the frameworks according to the all kinds of scales of mapping,it is necessary to select the logical projecting zones and planes that make the measuring distance to terms with the computing distance according to the control points.That is,correction errors of projection may not exceed the requirements of criterion. |
