Method: Coordinate Frame rotation (geog2D domain)
Remarks: Approximation derived ignoring time-dependent parameters and assuming ITRF94(1996.0) and WGS 84, plus NAD83(CORS94) and NAD83(HARN), can be considered the same within the accuracy of the transformation. Replaced by NAD83(HARN) to WGS 84 (3) (code 1901).

Unit: metre
Geodetic CRS: NAD83(HARN)
Datum: NAD83 (High Accuracy Reference Network)
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Information source: Guam Public Law 23-31 and Department of Land Management brochure "1993 Guam Geodetic Network".
Revision date: 2017-07-14
Scope: Cadastre, engineering survey, topographic mapping (large and medium scale).
Remarks: Replaces Guam 1963 / SPCS (CRS code 3993) from 1995. Guam Public Law 23-31 uses the name "NAD83" for NAD83(HARN). NAD83 is a system realized only in North America and different to NAD83(HARN).
Area of use: Guam - onshore.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: m.
