通过实例数据,对1980西安(参心)坐标系向2000(地心)坐标系转换过程中遇到的若干问题进行探讨,分析了参心坐标系大地高的粗差、公共点位于不同投影带、公共点位于不同高程抵偿面等因素对转换精度的影响。 更多还原

【Abstract】 This paper discussed the coordinate transformation from reference ellipsoid centric coordinate system to geocentric coordinate system using actual data and analyzed the effect factors including error of reference ellipsoid height,common reference points existing at different projection belts and common reference points existing at different height surfaces. 更多还原
