ANNEX I COMMON TYPES, DEFINITIONS AND REQUIREMENTS

6. COVERAGE MODEL

6.2. Coverages (Domain And Range)

6.2.1. Spatial object types
The package Coverages (Domain and Range) contains the following spatial object types:
Coverage (Domain And Range Representation)
Rectified Grid Coverage
Referenceable Grid Coverage

6.2.1.1. Coverage (Domain And Range Representation) (CoverageByDomainAndRange)
Coverage which provides the domain and range as separate properties.
This type is a sub-type of Coverage.
This type is abstract.

Attributes of the spatial object type CoverageByDomainAndRange
Attribute	Definition	Type	Voidability
coverageFunction	Description of how range values at locations in the coverage domain can be obtained.	CoverageFunction	
domainSet	Configuration of the domain of the coverage described in terms of coordinates.	Any	
rangeSet	Set of values associated by a function with the elements of the domain of the coverage.	Any	

Constraints of the spatial object type CoverageByDomainAndRange
The grid function shall only be valid for domains that are grids.

6.2.1.2. Rectified Grid Coverage (RectifiedGridCoverage)
Coverage whose domain consists of a rectified grid.
This type is a sub-type of CoverageByDomainAndRange.

Constraints of the spatial object type RectifiedGridCoverage
The domain shall be a rectified grid.
Grid points of a RectifiedGridCoverage shall coincide with the centres of cells of the geographical grids defined in Section 2.2 of Annex II at any resolution level.

6.2.1.3. Referenceable Grid Coverage (ReferenceableGridCoverage)
Coverage whose domain consists of a referenceable grid.
This type is a sub-type of CoverageByDomainAndRange.

Constraints of the spatial object type ReferenceableGridCoverage
The domain shall be a referenceable grid.
