摘要
There are many methods to convert the coordinate data from Beijing 1954 to WGS 1984.Each of the methods has different advantages.In practice,because of the data itself and its system parameter errors,the converted data cannot be applied normally.Based on ArcGIS,the paper applies mathematical algorithm to convert the coordinate data of Tianjin main route sign points from Beijing 1954 to WGS 1984.Experiments show that it is rapid to transform the data after rectifying the origin data which could correct and convert the data based on ArcGIS.And it has an important significance to the simulation of ship sailing on the main route for Tianjin and other related projects.
