# VerticalPositionValue

The relative vertical position of a feature.

## **Code list: LinkDirectionValue**

| Code                | Description                           |
| ------------------- | ------------------------------------- |
| onGroundSurface     | The feature is on ground level.       |
| suspendedOrElevated | The feature is suspended or elevated. |
| underground         | The feature is underground.           |

Where the VerticalPosition has not been determined, this attribute is empty, with a nilReason explicitly stated as ‘unknown’. A correct value does exist, but the methods employed by Ordnance Survey to date have not facilitated capture.
