EPSG:3785 DEPRECATED

Popular Visualisation CRS / Mercator -- Spherical Mercator (deprecated EPSG code wrongly defined)

Transform Get position on a map

Deprecated EPSG code for Spherical Mercator - wrong definition similiar to how deprecated ESRI:102113 is defined

Alternatives codes : 3857

Available transformations
to EPSG:4326
No other targets exist for this CRS

Selected transformation

Method: Geocentric translations (geog2D domain)

Remarks: Executes change of sphere/ellipsoid

Information source: OGP

Revision date: 2008-03-14

Attributes

Unit: metre

Geodetic CRS: Popular Visualisation CRS

Datum: Popular Visualisation Datum

Ellipsoid: Popular Visualisation Sphere

Prime meridian: Greenwich

Data source: EPSG

Information source: Microsoft.

Revision date: 2008-03-14

Scope: Web mapping and visualisation.

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)

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.
