Information source: OGP

Revision date: 2021-09-10

Attributes

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.
