坐标换带投影参数录入错误的数据纠正方法

Method for the Data Rectification of the Coordinate Projection and Zone Exchange Parameters Entry Error

针对如何对错误的投影数据进行纠正,介绍了通过数据的有效检核,探测误投影数据所采用的投影参数,然后进行数据的有效纠正。并以某县的行政区数据进行验证,结果证明该数据纠正方法是有效的,且此方法能实现零误差的数据转换。

During productive practice, we often obtain the erroneous result of projection and zone exchange due to the incorrect input parameters. According to this problem, in this paper we introduce the data rectification method, which employs an effective data check to detect the misuse projection parameters, and on this basis rectify the data. Finally, using a county area data to validate raised method, the results show that this method can correct the data effectively, and achieve zero error.
