Urban rail transportation topography of megacity is very complex,which has many forbidden measurement areas. This paper proposes a combined control network establishing method by using the static GPS,leveling,Gzcors,and Gzgeoid. Moreover,the key points of field data acquisition and the precision test method are analyzed. The forbidden measurement areas are locally replaced by remote sensing images. The results showed that the method used in this pro-ject,which can well meet the needs of urban rail transportation topographic of megacity,has certain reference significance to the implementation of similar projects.
