Based on data of multi-dimensional observation with total-station surveying system,the three-dimentional network adjustment model is set up.

DBSCAN improvement algorithm of deviation amendment based on observed data

As a case study,the largest Lyapunov exponent from the observations on a certain dam is calculated to be positive to prove that there exist the chaos phenomena in the observed data.

According to the theoretical study and in consideration of real situation of test,this paper emphasizes on the influence of observed data error on test results in detail,and confirm the reliability and applicability of this method resalting from the theoretical model for three dimensional geo stress measurements.

With the development of GPS and using in various fields, the received equipment of GPS using in our country are more and more, but for the observation data format of GPS is not united, It is difficult on calculation of GPS data, allowance togethor of GPS observation data for user and integration of GIS and GPS.
