Latitude (degrees north) and Longitude (degrees west) are expressed in degree-minute-second form. Chicago's Loop is at approximately 41°53'00" north and 87°37'00" west. These coordinates are taken from the US Geological Survey's listings, and in some cases are used (in conjunction with a GPS receiver) to resolve ambiguous listings.
"USGS Cell Name" is used for identifying and downloading maps or data from the US Geological Survey. The graveyard is not necessarily in the town named, but merely close to it. If "not listed" appears, this indicates that the cemetery is not in the USGS listings at all and was added manually, after its existance was verified through a site visit.
