Abstract: | An alternative datum transformation approach, which belongs essentially to the well known polynomial methods, is presented. Problems associated with datum transformation are mentioned. The concept of the developed approach is discussed. A comparison between the developed approach and similarity transformation based datum-shifts for Egypt is carried out. The results show that the developed approach gives significantly better accuracy. |
