Elevation spatial object forming part of a vector data set, which participates in the description of the elevation property of a real world surface. It consists of an identity base for all vector objects which can be included as part of an elevation data set.
-- Description --
It is an abstract feature type which generically describes every possible type of elevation vector object. It includes common attributes, properties and constraints for such spatial objects.

Description |
| beginLifespanVersion |
DateTime |
|
Date and time at which this version of the spatial object was inserted or changed in the spatial data set.
|
| endLifespanVersion |
DateTime |
|
Date and time at which this version of the spatial object was superseded or retired in the spatial data set.

|
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.

| propertyType |
ElevationPropertyTypeValue |
|
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.
