I have some geospatial data in a text file but I can't identify the coordinate system it is using. Coordinates were in a format like this: xxxxNx, xxxxxEx, where the x's are integers. I think it might be a naval or military format, but I'm not sure.
It would look something like this: "3506N8 13922E5"*
Any help would be appreciated.
*not a real example, may not be plottable.
