The vertical coordinate system (vcs) describes the datum used for vertical coordinates.  It only appears if a vertical coordinate system is known. Examples: "WGS 84 [geoid]" "WGS 84 / UTM zone 12S" - the vcs is not known. Valid inputs: "geoid" - Clears any existing vcs, then sets the VCS name to the input. "" - Clears the VCS from the name
