| 摘 要： | 结合地形图、Google Map获取相同区域坐标点的方法计算布尔莎模型七参数，并在ERDAS平台上构建Spheroid ．tab文件，实现影像从Xi＇an＿80向WGS＿84坐标转换。此方法可应用到不同数据源的栅格数据坐标转换，转换后的精度误差范围可控制在7m之内，并可使大尺度、大范围的不同基准面椭球体下的影像坐标转换得到实现。

| Abstract: | Combined with the topographic Map ,Google Map method is used to obtain the same area coordinates and to calculate Boolean Sally seven parameters model ,and the construction of Sphe-roid parameters is to realize the image from Xi＇an_80 to WGS_84 coordinate transformation .It has proved that this method can realize different sources of raster data conversion ,the converted precision error range can be controlled within 7 m .With large scales ,a wide range of images under different da-tum ellipsoid coordinate transformation has the reality significance . |
