Deepest Depth Below Surface Level (DZP)

DGIF baseline 2026-1, the latest. Earlier baselines: timemap.

Name

deepDepthBelowSurfLevel

Datatype

Real

Definition

The distance measured from ground or water level (uphill/upstream side of the feature) to the deepest point of the feature.

Description

May be used to measure the depth of an inland waterbody (for example: a lake), the depth of a terrain surface depression or excavation (for example: a crevice or trench), the distance to the deepest point of a drilled feature (for example: a water well or borehole) or the distance to the deepest point of a feature located entirely underground (for example: a cave chamber). In the case of a feature located below a waterbody (for example: a non-water well) the reference surface is the waterbody bottom, rather than the waterbody surface.
