Bo Zeng · 2012
GZCORS has a fast, accurate, comprehensive, all-weather positioning feature. In this paper, completion and accep- tance of the Guangzhou Asian Games City underground pipeline as an example, it describes the mode of operation using GZCORS for control measurement instead of level control wire. The mode effectively solves the contradictions between a large number of pipelines and few control point. It has broad application prospects in the urban underground pipeline detection in context of rapid urbanization.
