Geodetic measuring methods and shape estimation of concrete thin shell surface

The geodetic measurements of surface geometry can be performed with new laser scanning technologies. This paper presents the results of such measurements of external surface of cooling tower using Leica TCRP 1201+ tacheometer and Image Station 03 video tacheometer. The overlapping data sets of consecutive scans were investigated in order to propose a method to compound partial surface scans. The data analysis included estimation of systematic errors in common sections of scans. The results of obtained surfaces were compared with precise point measurements using Leica TCRP 1201+.
