F26.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.
