Isolated Area - Spatial object type

Definition: Delimitation of an area of the Earth's surface where an isolated part of the elevation model exists. Its outside surroundings have no elevation information.

Description: SOURCE Adapted from "IslandArea" [GIS4EU D3.5].NOTE 1 It includes the delimitation of any island of elevation data which are isolated from the main DEM. They may be included inside void areas.NOTE 2 Isolated areas can be useful as masks when calculating a more appropriate or accurate DEM.

Stereotypes: voidable

Valuetype: DateTime

Definition: Identification of a local vertical coordinate reference system not included in a registry, which is used to refer depth measurements.

Description: NOTE This data type is applicable only to bathymetric vector objects.EXAMPLE Local datums for referring depths in lakes and navigable rivers.

Multiplicity: 0...1

Valuetype: ChartDatum

Definition: Attribute categorizing the elevation vector object as a land-elevation or a bathymetry spatial object. It determines the elevation property represented by the object.

Description: EXAMPLE Height, depth.
