Coastline - Spatial object type

Definition: A special case of a shoreline defined as the shoreline at Mean High Water (MHW). Where there is not significant variation in water level, Mean Sea Level (MSL) can be used as a substitute for MHW.

Description: This feature type is designed for the general use case where the land:sea boundary is required to support general discovery and viewing of datasets. It is not designed to infer any political boundaries. The purpose is to provide a consistent overview of European marine extent and for this reason a single tidal extent is selected. This is consistent with IHO-57 definitions

Definition: A section of shoreline.

Multiplicity: 1...*

Valuetype: ShoreSegment

Definition: The water level used when defining this shoreline (e.g. meanHighWater)

Multiplicity: 1

Valuetype: WaterLevelValue

Definition: A geographical name that is used to identify a hydrographic object in the real world. It provides a 'key' for implicitly associating different representations of the object.

Description: EXAMPLE A standing water in a mapping view may share the same geographical name as a WFD lake in a reporting view, implying they are both representations of the same real world object.

Valuetype: GeographicalName

Definition: An identifier that is used to identify a hydrographic object in the real world. It provides a 'key' for implicitly associating different representations of the object.

Description: NOTE 1 The identifier may be a national hydrological identification code.NOTE 2 More than one identifier may be required, for instance a watercourse may be assigned different identifying codes under national and European schemes.EXAMPLE A lock in a mapping view may share the same identifier as a hydro node in a network view, implying they are both representations of the same real world object.

Type Invariant

Status Approved

Note /*Coastline is a special case of shoreline at Mean High Water Level. Coastline is the boundary between land and sea to be used for viewing, discovery and general purpose applications where a land/marine boundary is required. Where there is not significant variation in water level, MSL can be used as a substitute for MHW */
