Abstract

Abstract:

The spatial angle intersection method in limit field and under bad visibility environment is discussed. The monitoring errors of spatial angle intersection method and azimuth and elevation method are theoretically analyzed. It has been proved that the construction precision can meet the requirements when choose the rational positions of layout points and stations using total stations.

Key words: total station, surveying, forward intersection, backward intersection, error propagation, precision analysis
