Abstract

The problem of converting the points in a coordinate system to another coordinate system is very common in Geodesy and Photogrammetry Engineering. The coordinates in a coordinate system can be derived from the definite coordinates of the points in another system by means of coordinate transformation. The type of transformation is determined according to the objective of the transformation and the number of the common points in definite coordinates. Similarity (Helmert), Affine and Projective transformation methods have been used mostly in two-dimensional transformation. In this study, a program was developed in DELPHI programming language to compare the transformation method. By this program, discrepancy point test can be done by using the both system coordinates of the common points, transformation parameters according to the matched points can be determined and with the parameters, the second system (target system) coordinates can be calculated by using definite coordinate points in the first system (source system).
