| Abstract: | We compare two big-rotation-angle 3D datum transformation models between improved Bursa model and simplified model. The advantages and disadvantages and usage scope of the two models are discussed through two examples. At the end, we mention how to choose the common points which are needed in 3D datum transformation. |
