摘　　要：利用坐标投影边长归化关系,结合Excel表格,采用数学转换关系解决投影长度变形值超限的问题,确保确定的坐标系满足地籍调查成果和实现调查成果在统一坐标系下不同比例尺数据及图件融合的精度要求,满足生产需求,提高作业效率。This paper described the use of coordinate projection side naturalized relations, used Excel spreadsheet program to edit formulas, and used mathematical converting relationship to solve the length of the projection distortion to overrun. This method would ensure coordinate system to fulfill the cadastral survey results, and the results realized the investigation of accuracy of data and maps of different scales integrated under the unified coordinate system, to fulfill production needs, and improve operational efficiency.
