I recently acquired a shapefile that when added in ArcMap 10.2, the software says it has an unknown spatial reference system. The X and Y coordinates are both 6 digit coordinates (for example, 712568.799, 257083.471).
I would like to be helped on how to convert these coordinates to Arc 1950 UTM Zone 36s which is a system used in Malawi. If the Y coordinate had 8 in front it could have worked perfectly but this is not the case.
.PRJfile included with the shape file? I'm not an ArcGIS user but I'm pretty sure the projection data is usually stored in a.PRJfile with the shapefile format. – T_Bacon Apr 19 '17 at 14:02
