|
Description of how range values at locations in the coverage domain can be obtained. |

Any |
|
Configuration of the domain of the coverage described in terms of coordinates.
-- Description --
NOTE The values of this property will typically be constrained in subtypes to specific spatial and/or temporal geometries. |
| rangeSet |
Any |
|
Set of feature attribute values associated by a function with the elements of the domain of the coverage. |
| beginLifespanVersion |
DateTime |
|
Date and time at which this version of the spatial object was inserted or changed in the spatial data set.

EX_Extent
|
|
Extent of the spatiotemporal domain of the coverage.
-- Description --
SOURCE [ISO 19123:2005].
NOTE 1 The data type EX_Extent, is defined in ISO 19103. Extents may be specified in both space and time.
NOTE 2 The domain extent shall be specified at least in space by using EX_BoundingPolygon, EX_GeographicBoundingBox or EX_GeographicDescription. The whole geographic extent of the elevation coverage is affected, including areas where grid points hold nil reason values.
|
| endLifespanVersion |
DateTime |
|
Date and time at which this version of the spatial object was superseded or retired in the spatial data set.

| inspireId |
Identifier
|
|
External object identifier of the spatial object.
-- Description --
NOTE An external object identifier is a unique object identifier published by the responsible body, which may be used by external applications to reference the spatial object. The identifier is an identifier of the spatial object, not an identifier of the real-world phenomenon.

-- Description --
EXAMPLE Height, depth.
|
| surfaceType |
SurfaceTypeValue
|
|
Attribute indicating the type of elevation surface that the coverage describes in relation to the Earth's bare surface.
