Abstract:

Total station is widely used in various measurements coordinates as the observation values play an important role in the data processiong. The authors adjusted the coordinate observation values combined with other conventional observations deformation data using the least square filter. The results indicated that the precision was obviously improved with the 1.35 mm decrease of maximum point error and 0.94 mm decrease of  the weakest point error, and the constraints of different observation also increased the reliability of the least square filter adjustment.

Key words: least square, filtering, deformation monitoring, coordinate value
