Unit: metre
Geodetic CRS: Popular Visualisation CRS
Datum: Popular Visualisation Datum
Ellipsoid: Popular Visualisation Sphere
Prime meridian: Greenwich
Data source: OGP

Revision date: 2008-03-14
Scope: Certain Web mapping and visualisation applications.
Remarks: Uses spherical development. Relative to an ellipsoidal development errors of up to 800 metres in position and 0.7% in scale may arise. Some applications call this WGS 84. It is not a recognised geodetic system: see WGS 84 / World Mercator (CRS code 3395)
Method: Geocentric translations (geog2D domain)
Area of use: World between 85.06°S and 85.06°N.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: m.
