Void Area - Spatial object type

Definition: Area of the Earth's surface where the elevation model is unknown because of missing input data. This area shall be excluded from a DEM.

Description: SOURCE "ObscureArea" [GIS4EU D3.5].NOTE 1 A void area may contain a number of isolated areas with elevation data. These are considered as holes of the container void area.NOTE 2 Void areas can be useful as masks when calculating a more appropriate or accurate DEM.

Attributes

Definition: Represents the geometric properties of the spatial object.

Multiplicity: 1

Valuetype: GM_Surface

Definition: Date and time at which this version of the spatial object was inserted or changed in the spatial data set.

Multiplicity: 1

Stereotypes: voidable

Valuetype: DateTime

Definition: Date and time at which this version of the spatial object was superseded or retired in the spatial data set.

Multiplicity: 1

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.

Multiplicity: 1

Valuetype: ElevationPropertyTypeValue
