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.
Zones of the State Plane Coordinate System
The following abbreviations are used in the State Plane tables:
Tr Merc = Transverse Mercator
Lambert = Lambert Conformal Conic
Oblique = Oblique Mercator (Hotine)
Polycon = Polyconic
