摘要
利用布尔莎七参数转换模型对全国矿业权实地核查中的北京54坐标系和西安80坐标系间坐标的转换进行了实例演算。介绍了布尔莎七参数转换函数模型、坐标转换方法及公共点的选取和精度评定。
This paper indicated the Bursa seven--parameters of the transfer function model,the coordinate system trans formation methods, the common point selection and accuracy assessment. As well as the Bursa seven--parameter transformation model make a instance of calculations that Coordinate System Transformation by 1954 Beijing and 1980 Xi'an in The Field Veri- fication of The National Mining Rights.
