    Abstract
  • Based on the high-precision quasi-geoid refinement model of Jiaxing City and the JXCORS of Jiaxing City, combined with the results of the construction of modern surveying and mapping datum system and the reconnaissance of two projects in Jiaxing City, The derivation calculation and test analysis comparison of GNSS static measurement and network RTK measurement instead of grade leveling measurement are carried out. Finally, the feasibility of replacing grade level measurement is verified, which has a good application value for Urban Surveying and mapping.
