Correction and application of the horizontal distance observed with total station
Jianhua Wang · Cehui kexue · 2011
In the paper.the problem that the mutual deviation is larger than tolerance in reciprocal observation by total station was analyzed firstly and then the difference of the formula for calculating horizontal distance on the different level surface using the slope distance was pointed out.To solve the difference between the formulae built in the current market instruments and used in the practical engineering application,the precise and adjusted formula was derived.At last,the data observed in the control network of the water diversion project from Hongyan to Stone River were corrected with the formula.The good result showed that the formula obtained in the paper was reasonable.
