The vertical coordinate system (vcs) describes the datum used for vertical coordinates. The vcs name, if known, will appear in square brackets as part of the coordinate system name. Examples: "WGS 84 [geoid]" "WGS 84 / UTM zone 12S" - the vcs is not known. "WGS 84 / UTM zone 12S [NAVD88]" Valid inputs: "NAVD88" - Clears existing vcs, if any, and sets the VCS name to "NAVD88". "" - Clears the vcs
