Title: Calculation of the Transformation Parameters between Local and Global Coordinate Systems
Author: Alfadul, Hamza Alhassan Alabbas
Abstract: The main objective of this research was to comparebetween Adindan and WGS84 using three different models: the three translations (ΔX, ∆Y, ∆Z) model, the five Parameters (ΔX, ∆Y, ∆Z,∆a (semi-major axis), ∆f (flattening)) model and the seven Parameters (〖ΔX,∆Y,∆Z,R〗_X,R_Y,R_Z,Δl)model, by calculating the transformation parameters. The data used for this study consisted of 59 common points, four of them were used for the calculation of the parameters, and the rest of the points were used as validation data. Moreover the research investigated the use of the three and five Parameters models as alternatives to the complicated seven Parameters model. The results revealed that the obtained values of parameters were very close to those given by the internationally adopted seven parameters model (≤ 1.5 meter). It can then be concluded that three and five Parameters models can be used instead of seven Parameter model, when the tolerance is less than 1.5 meter.
