| Abstract: | An introduction is made to briefly describe the existing conditions of Africa state survey coordinates, the principle of selecting port coordinate system and the calculation method of UTM projection length deformation. The way and steps to choose and optimize African ports coordinate system are put forward. An Africa port project practice is used to expound the process of optimizing engineering coordinate system and the effect achieved, which will provide references for other similar projects. |
