Abstract:
Taking the underwater topographic survey for the Hangzhou Bay Major Bridge as an example, the factors affecting measurement accuracy and the general principle of underwater topographic survey and the working procedure technologies were discussed in terms of keeping the depth measurement and the location at the same time, coordinates translation. Based on the real data, the emphases was on how to ensuring the precision of this project through ensuring the position and the depth surveying at the same time and the coordinates converting precision.
