Element information

Content

• Choice [1..1]
  • gml:inverseFlattening    Inverse flattening value of the ellipsoid. Value is a scale factor (or ratio) that has no physical unit. Uses the MeasureType with the restriction that the unit of measure referenced by uom must be suitable for a scale factor, such as percent, permil, or parts-per-million.
  • gml:semiMinorAxis    Length of the semi-minor axis of the ellipsoid. Uses the MeasureType with the restriction that the unit of measure referenced by uom must be suitable for a length, such as metres or feet.
  • gml:isSphere    The ellipsoid is degenerate and is actually a sphere. The sphere is completely defined by the semi-major axis, which is the radius of the sphere.
