struct Tinman.Georef.CoordSys

Short Name:
  • struct CoordSys
Fields:

Describes a coordinate system for georeferencing.

A 3D geographic coordinate system has the following axes:

  1. X: Geodetic longitude
    Angle from the prime meridian plane to the meridian plane passing through the given point, eastwards treated as positive.

  2. Y: Geodetic latitude
    Angle from the equatorial plane to the perpendicular to the ellipsoid through a given point, northwards treated as positive.

  3. Z: Ellipsoidal height
    Distance of a point from the ellipsoid measured along the perpendicular from the ellipsoid to this point. Positive if upwards or outside of the ellipsoid.

A projected coordinate system has the following X and Y axes:

  1. X: Easting
    East pointing axis used in 2D projected coordinate systems.

  2. Y: Northing
    North pointing axis used in 2D projected coordinate systems.

Vertical coordinate systems have a different Z axis, usually gravity-related height or depth.
