- Allentown, Pennsylvania redirects here
Philadelphia is split between two primary graticules, as the city is bisected by the 40th parallel. The southern Philadelphia graticule is at 39 N, -75 W. The northern graticule is at 40 N, -75 W. Parts of the Far Northeast are in the Newark, New Jersey graticule, and many of the South Jersey suburbs are in the Atlantic City, New Jersey graticule; those may be more convenient to get to for some people, depending on the coordinates of the day.
