NAD83(2011) / ICS83-Macomb (ftUS)

Puerto Rico , accuracy 2.0 m, code 9774 (default) [3]

Selected transformation

Method: Geocentric translations (geog2D domain)

Remarks: For many purposes NAD83(2011) can be considered to be coincident with WGS 84. This approximation ignores the ~2.2m offset of NAD83 from the geocentre, the low accuracy of the WGS 84 ensemble and the application of tectonic plate motion to WGS 84 data.

Attributes

Unit: US survey foot

Geodetic CRS: NAD83(2011)

Datum: NAD83 (National Spatial Reference System 2011)

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: Guide to the Illinois State Plane Coordinate System, https://clearinghouse.isgs.illinois.edu

Revision date: 2023-02-02

Scope: Engineering survey, topographic mapping (large and medium scale).

Remarks: Part of the Illinois Coordinate System of 1983 33-zone system. State law for SPCS83 defines use of US survey feet. This CRS was designed in NAD 83 ftUS but is otherwise based on the NGS guidelines for the NATRF2022 project.

Area of use: United States (USA) - Illinois - counties of Brown, McDonough and Schuyler.

Coordinate system: Cartesian 2D CS. Axes: northing, easting (N,E). Orientations: north, east. UoM: ftUS.
