How is the State Plane Coordinate system set up? Can GPS provide coordinates in these values? What about Public Land Survey System (PLSS) readouts?
The State Plane Coordinate System (SPCS) is a plane coordinate system (N-S and E-W lines are perpendicular) in which each individual state has from one to six zones, depending on the state's size and shape.
Trails and symbols are shown clearly. A comprehensive legend appears on each map. Since each map is unique, placement of the legend varies.
Do you have prepared page-size maps of the United States or of my State that I can print from my computer?
The National Map small-scale collection, previously accessed through the National Atlas, offers plenty of choices in page-size maps.
The online version of the National Atlas (officially known as The 1997-2014 Edition of the National Atlas of the United States) (formerly at nationalatlas.gov) was removed from service on September 30, 2014.
GNIS data is available from a number of sources and services.
