The maps below show that SPCS2022 will have up to three zone layers in each state, and the number of zones will vary greatly between states (click on the maps to get higher resolution versions). Every U.S. state and territory will have a statewide zone.
Maps. Preview the Modernized NSRS on the NGS Alpha Web Site! Below are maps of both the 1927 and 1983 versions of SPCS (select each one to get a higher resolution version). View a map of the entire SPCS and a map depicting SPCS 83 legislation and foot version. State Plane Coordinate System of 1983.
State Plane Coordinate System Rick King compiled and organized the information on this page, long hosted at the now defunct home.comcast.net/~rickking04/gis/spc.htm. A quick Google search shows almost 400 links to that page from across the geospatial community, from universities to professionals to students.
The State Plane Coordinate System (SPCS) is a set of 125 geographic zones or coordinate systems designed for specific regions of the United States. Each U.S. state contains one or more state plane zones, the boundaries of which usually follow county lines.
The State Plane Coordinate System (SPCS), which is only used in the United States, is a plane coordinate system (north-south and east-west lines are perpendicular) in which each individual state has between one to six zones, depending on the state's size and shape.
The map below shows a thematic map of all the projections that the State Plane Coordinate System uses. It separates which zone uses Lambert Conformal Conic, Transverse Mercator, and Hotine Oblique Mercator projections. SPCS 27 and SPCS 83.
SPCS2022 Zone Information. Preliminary information about SPCS2022 is available via the links listed below, including complete zone definitions and example coordinate computation results for every zone.
The Universal Transverse Mercator (UTM) coordinate system and the United States National Grid (USNG) are not NGS products. However, NGS currently provides UTM and USNG coordinates and will continue to do so in the Modernized NSRS.
SPCS is a system of large-scale conformal map projections support surveying, engineering, and mapping activities throughout the U.S. and its territories.
Continuously updated SPCS2022 design map images and associated map data are available for download. The maps show linear distortion at the topographic surface for SPCS2022, along with existing State Plane and Universal Transverse Mercator (UTM) for comparison.
