Sometimes the projection information appears in a .prj file (sharing the base name of the shapefile). If not, then you just gotta know. (The data provider should tell you.) You need GIS software, or the equivalent, to unproject the coordinates. This means converting the shapefile within the GIS into another shapefile (or the equivalent) and then exporting its new coordinates. | |
