The gml:coverageFunction property describes the mapping function from the domain to the range of the coverage.The value of the CoverageFunction is one of gml:CoverageMappingRule and gml:GridFunction.If the gml:coverageFunction property is omitted for a gridded coverage (including rectified gridded coverages) the gml:startPoint is assumed to be the value of the gml:low property in the gml:Grid geometry, and the gml:sequenceRule is assumed to be linear and the gml:axisOrder property is assumed to be "+1 +2".
