摘　　要：为了使GNSS测量成果更好地服务于城市建设,并保持与原有数据的一致性,需将其归算至城市坐标系。本文阐述了城市坐标系建立的方法理论,总结了将GNSS测量成果归算至城市坐标系的一般步骤,并利用GNSS实测数据进行验证与分析,提出了一些合理化的建议,为GNSS测量成果归算至城市坐标系提供参考和借鉴。In order to make GNSS measurement results better serve the city and maintain the consistency of the original data,it needs to be transform into the city coordinate system.This paper describes the method theory of urban coordinate system establishment,summarizes the general steps of the transformation of GNSS measurement results to urban coordinate system,uses GNSS data for verification and analysis,and puts forward some reasonable suggestions,which provides reference for the transformation of GNSS measurement results to urban coordinate system.
