State Plane is an X,Y coordinate system (not a map projection). State Plane zones divide the US into over 130 sections, each with its own projection surface and grid network. With the exception of very narrow states, such as Delaware, New Jersey, and New Hampshire, most states are divided into multiple (2 - 10) zones. The Lambert Conformal projection is used for zones extending mostly in an east-west direction. The Transverse Mercator projection is used for zones extending mostly in a north-south direction. Alaska, Florida, and New York use either Transverse Mercator or Lambert Conformal for different areas. The Aleutian panhandle of Alaska is prepared on Oblique Mercator projection.

Zone boundaries follow state and county lines, and because each zone is small, distortion is less than one in 10,000. Each zone has a centrally located origin and a central meridian that passes through this origin. Two zone numbering systems are currently in use, but other numbering systems exist

  • USGS code system
  • National Ocean Service (NOS) code system

This system contains the following unique parameters:

State Plane Zone    Enter either the USGS zone code number as a positive value, or the NOS zone code number as a negative value.

NAD    Select which datum to use.

NAD27    North America Datum 1927

NAD83    North America Datum 1983

HARN    High Accuracy Reference Network

NAD83 (NSRS2007)    North American Datum 1983 - National Readjustment of NAD83 introduced in 2007 in which adjustment uses all data in National Spatial Reference System.

  • NAD27 is based on the Clarke 1866 spheroid.
  • NAD83 and HARN are based on the GRS 1980 spheroid. Some zone numbers have been changed or deleted from NAD27.

Tables for both NAD27 and NAD83 zone numbers follow. Each table includes both USGS and NOS code systems.

The following abbreviations are used in the State Plane tables:

Tr Merc = Transverse Mercator

Lambert = Lambert Conformal Conic

Oblique = Oblique Mercator (Hotine)
