EPSG:9001

IGS97

Attributes

Unit: metre

Geodetic CRS: IGS97

Datum: IGS97

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: International GNSS Service (IGS).

Revision date: 2019-05-17

Scope: Geodesy.

Remarks: Adopted by the International GNSS Service (IGS) from 2000-06-04 through 2001-12-01. Replaced by IGS00 (CRS code 9004). For all practical purposes IGS97 is equivalent to ITRF97.

Area of use: World.

Coordinate system: Cartesian 3D CS (geocentric). Axes: geocentric X Y Z. Orientations: X and Y in equatorial plane, X positive through intersection with prime meridian, Y through 0°N 90°E. Z axis parallel to mean earth rotation axis and positive towards North Pole. UoM: m.
