摘　　要：测绘地理信息成果常利用坐标转换的方法实现不同成果坐标的转换。利用区域高精度控制点平差成果进行坐标转换残差较小,一般均能通过内符合检查。对于需要对区域内多套控制点成果计算其相互转换关系,采用传统的方法计算过程烦琐,效率低下。本文提出利用坐标转换模型,通过统一坐标成果名称,配置其元数据信息,批量进行坐标转换参数计算的方法,大大提高了多套控制点成果坐标参数计算的效率。The coordinate transformation method is often used to realize the coordinate transformation of different surveying and mapping geographic information data.The residual error of coordinate transformation by using the adjustment results of regional high-precision control points is very small,which can generally pass the internal consistency check.The traditional method is cumbersome and inefficient to calculate the transformation relationship of multiple sets of control points in the region.In this paper,the coordinate transformation model is used to unify the coordinate result name,configure its metadata information,and batch coordinate transformation parameter calculation method,which greatly improves the efficiency of coordinate parameter calculation of multiple sets of control point results.
