| 摘 要： | 目前四等三角高程测距导线采用规范不同,测回数也不一样.随着仪器设备精度的提高,达到规范要求的精度,就不需要测量这么多测回数,比如,四等三角高程导线垂直角测回数可以减少到两个测回,同样可以满足四等三角高程测距导线的精度,并且可以减少部分工作量.

| Abstract: | The specifications for the implementation of fourth-order trigonometric height traversing are different,and the required number of observation set is also different.But the surveying accuracy of equipments is improved.In order to achieve the accuracy required in the specification,the number of observation set could be reduced.For instance,the number of vertical angle observation set for fourth-order trigonometric height traversing could be reduced to two,which could meet the accuracy requirement of fourth-o... |
