摘　　要：介绍了应用常规技术建立的以高程面为边长归算参考面的城市坐标系和国家大地坐标系在数据处理方面的异同;以及GPS技术建立城市现代坐标系时区域性椭球的选取和GPS控制网归算到城市坐标系地面网的方法。This paper introduces the difference of date processing between the urban coordinate system with certain height plane as the reference level for the reduction of side length and the national geodetic coordinate system and the way of determining regional ellipsoidal surface when establishing the urban modern coordinate system by GPS technology and the transformation from the GPS control network to the terrestrial network attached to the urban coordinate system.

关 键 词：城市坐标系 边长归算 区域性椭球面 GPS控制网
