In this paper,we take an overseas waterway engineering surveying and mapping project as an example to discuss two major problems during the implementation of the project. They are the determination of the plane coordinate system and the elevation datum under the situation that the basic surveying material is lacking. This paper summarized the technical scheme,implementation plan,material processing and data analysis method that were adopted in the sample project. The results and conclusions can provide useful reference for the domestic surveyors in the similar surveying projects.
