ETRS89-ALB [CORS]

Attributes

Unit: metre

Geodetic CRS: ETRS89-ALB [CORS]

Datum: ETRS89-ALB [CORS]

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: EUREF "Overview of national realizations of the integrated geodetic reference in Europe", https://doi.org/10.71603/NatRefEurope

Revision date: 2025-10-17

Scope: Geodesy. Active GNSS network / Continuously Operating Reference Station (CORS) network.

Remarks: Used for the coordinates of the 27 reference stations of the active ALBCOR network in Albania. Differences with the official KRGJSH realization (CRS code 11045) used for other spatial referencing are negligible (5-7 mm for all components).

Area of use: Albania - onshore and offshore.

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.
