  • coord: This is a list of values representing the coordinates.
  • extraHeight: This is a separate value for the altitude/height. It is used: 1) if altitudes are stored in an own reference system (i. e. epsgCode refers to a GeodeticCRS rather than a CompoundCRS); 2) if there are no long/lat coords given or known but a height. See <geoCoord> notes.
  • epsgCode: This is an URI pointing to the EPSG-Code (external link) as reference system for the coordinates in coord.
  • heightEpsgCode: This is an URI pointing to the EPSG-Code (external link) for the separate altitude reference system.
