Abstract: A method of recovering coordinate system information for a geographic data file for which coordinate system information is unavailable. The method includes obtaining a raster image corresponding to the geographic data file, and correlating the raster image to the earth's surface. A list of probable coordinate systems for the raster image is generated, and a statistical analysis is performed for each likely coordinate system candidate. The suggested coordinate systems are then ranked using statistical analysis.
