Topocentric height


Unit: metre

Data source: EPSG

Information source: OGP

Revision date: 2007-10-29

Orientation: up

Abbreviation: W

Axis order: 3..

Remarks: Used in topocentric coordinate-systems related geometrically to the ellipsoid, as opposed to those that are gravity-related. If the topocentric origin is on the ellipsoid surface, topocentric height = ellipsoidal height.

Coordinate system: Cartesian 3D CS (ellipsoid-based Topocentric). Axes: easting, northing, topocentric height (U,V,W). Orientations: east, north, up. UoM: m.

Description: Vertical axis of a Cartesian 3D CS which is perpendicular to the ellipsoid and passes through the topocentric origin. Positive is up at the topocentric origin.
