Spot Elevation - Spatial object type

Definition: Point spatial object which describes the elevation of an Earth's surface at a specific location. It provides a single elevation property value.

Description: NOTE 1 It often represents a singular point in the morphology of a land or water body''s floor surface.NOTE 2 The attribute propertyType is equal to ''height'' in the case of spot heights. It is equal to ''depth'' in the case of spot depths.

Attributes

Definition: Class of spot elevation according to the LAS specification of the American Society for Photogrammetry and Remote Sensing (ASPRS).

Multiplicity: 1

Stereotypes: voidable

Valuetype: SpotElevationClassValue

Definition: A geographical name that is used to identify a named land or water body's floor location in the real world, which is represented by the spot elevation spatial object.

Multiplicity: 0...*

Stereotypes: voidable

Valuetype: GeographicalName

Definition: Represents the geometric properties of the spatial object.

Multiplicity: 1

Valuetype: GM_Point

Definition: Value of the elevation property of the spatial object referred to a specific vertical coordinate reference system.

Multiplicity: 1

Valuetype: DirectPosition

Definition: The type of elevation spot.

Multiplicity: 1

Stereotypes: voidable

Valuetype: SpotElevationTypeValue

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Definition: Date and time at which this version of the spatial object was superseded or retired in the spatial data set.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