To obtain the bottom feature points of the elements of three-dimensional topographic map is quite simple, the key is how to gain the top feature points of the terrain elements using total station. Several relevant methods were studied in this paper by corresponding measured data, and came to the conclusion that the surveying of three-dimensional digital terrain map by total station could be feasible.
