CORRECTION OF CADASTRAL MAPS USING DIFFERENT ADJUSTMENT METHODS

Abstract

Cadastral work in Absheron during the land reform period in 1996. There are several types of cadastral plans created with different production methods, coordinate systems, basic types, and measurement and acquisition methods. The Krassovsky coordinate system (SK-42) is used in land reform by scanning top plans. Later, in the cadastral work, the coordinates of the computer programs used to convert these map coordinates to WGS-84 coordinates were copied. Complex development has occurred in the existing cadastral system. In the WGS-84 coordinate system, errors occur when using coordinates obtained from the GNSS in plans created on the basis of the Krassovsky coordinate system (SK-42). These errors depend on differences in ternary spatial Cartesian coordinate systems, ellipsoidal or tometric heights, planar projections, and planar rectangular coordinate systems. Assigning the necessary geodetic methods to the state national coordinate systems of the existing cadastral maps is a repair. There are many coordinate transformation methods for this purpose. Although the least square (LS) adjustment method is widely used, it has some disadvantages in determining measurement errors. Least value of the error measurement (LAV) and its impact on other measurement results. For the final budget parameters, the generalized least squares (TLS) method is often used. In such transformations, the solution of changing the affine transformation method also depends on the adjustment of the obtained unique and most suitable parameters. The method of coordinate transformation was applied when the inconsistencies were not eliminated during the blocking of cadastral data to the redrawn cadastral maps in the WGS-84 coordinate system.
