摘要
基于格网的坐标转换方法可提供高精度的坐标转换,因而在许多国家得到广泛应用。文章采用实测数据验证了该方法在我国应用的有效性,并对国外采用的NADCON和NTv2两种格网文件格式进行了分析,针对我国当前情况提出了一些想法和建议。
The grid-based coordinate transformation method is widely used in some countries for its high transformation accuracy.In this paper,grid-based coordinate transformation is proved to be efficient for the transformation in our country by adopting real data in the computation.Grid file format such as NADCON and NTv2 which are adopted in foreign countries are analyzed and some ideas and suggestions are proposed.
