【Abstract】 The backward intersection of two point is the most simple method of the intersection fixed point. By both of the theoretical and simulating methods,the different observed angles,the known distance and the precision of the surveyed angle have been calculated and comparied.The conclusion shows that there is a direct effect of the intersection graphic on the precision of the point measurement.It has provided some valuable data for the field work in special area.更多还原
