摘要
通过全球定位系统(GPS)在1/万外业控制不同构网的精变分析,对于小比例尺特别是三角点稀少地区,控制网的布站时,应多采用闭合网,这样可以在相同的条件下提高网的精变。
Through GPS in accuracy change analysis of1:10000field control different nets,for small-scale especially less known triangle points area,the layout of control nets should adopt close nets so that the accuracy of nets can be raised in the same condition.
