The degree grid for GEOREF for the GJ 15 degree grid square, corresponding to, roughly, the eastern United States.
This graphic was created by software written specifically for the World Geographic Reference System (GEOREF) article in the Wikipedia. The background image is a Blue Marble product of NASA's Earth Observatory. It was subject to a Lambert conformal conic projection, and given appropriate markup. The observed pattern of one degree squares is present in all 15 degree squares of this grid system. The example in the GEOREF article refers to GJPJ, which has been darkened in this graphic.
