Information source: OGP
Revision date: 2012-08-10
Orientation: down
Abbreviation: D
Axis order: 1..
Remarks: Generally is a straight line through the reference surface, but there may be engineering applications where depth follows the plumb line; because of the short distances and near parallelism involved the two are considered to be insignificantly different.
Coordinate system: Vertical CS. Axis: depth (D). Orientation: down. UoM: ft.
Description: Distance measured perpendicular to a reference surface, positive downwards.
