## Depth

### Attributes

Unit: metre

Data source: OGP

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: m.

Description: Distance measured perpendicular to a reference surface, positive downwards.
