Pima County Coordinate System (PCCS) Report
Pima County Coordinate System (PCCS) Zone 1 East*
Linear unit: International foot (ift)
Geometric reference system: North American Datum of 1983 (NAD 83)
Reference ellipsoid: Geodetic Reference System of 1980 (GRS-80)
Projection: Oblique Mercator (local grid origin)
Latitude of local grid origin: 32° 15’ 00” N
Longitude of local grid origin: 111° 24’ 00” W
Northing at local grid origin: 800,000.000 ift
Easting at local grid origin: 160,000.000 ift
Skew axis scale at local origin: 1.000 110 (exact)
Skew axis azimuth at local origin: +45° 00’ 00”
* Also known as a Hotine OM or rectified skew orthomorphic (RSO) projection. Local origin also referred to as “center.” Can also be defined using the “true” or “natural” origin.

Pima County Coordinate System (PCCS) Zone 4 Mount Lemmon **
Linear unit: International foot (ift)
Geometric reference system: North American Datum of 1983 (NAD 83)
Reference ellipsoid: Geodetic Reference System of 1980 (GRS-80)
Projection: Lambert Conformal Conic (single parallel)
Standard parallel and grid origin: 30° 30’ 00” N
Longitude of central meridian: 110° 45’ 00” W
Northing at grid origin: -620,000.000 ift
Easting at central meridian: 30,000.000 ift
Scale factor on standard parallel: 0.999 800 (exact)
** An alternative two-parallel definition can be used for this zone if necessary.
