gml:CoverageFunctionType

Complex type information

Choice [1..1]
- gml:MappingRule
- gml:CoverageMappingRulegml:CoverageMappingRule provides a formal or informal description of the coverage function. The mapping rule may be defined as an in-line string (gml:ruleDefinition) or via a remote reference through xlink:href (gml:ruleReference). If no rule name is specified, the default is 'Linear' with respect to members of the domain in document order.
- gml:GridFunctiongml:GridFunction provides an explicit mapping rule for grid geometries, i.e. the domain shall be a geometry of type grid. It describes the mapping of grid posts (discrete point grid coverage) or grid cells (discrete surface coverage) to the values in the range set. The gml:startPoint is the index position of a point in the grid that is mapped to the first point in the range set (this is also the index position of the first grid post). If the gml:startPoint property is omitted the gml:startPoint is assumed to be equal to the value of gml:low in the gml:Grid geometry. Subsequent points in the mapping are determined by the value of the gml:sequenceRule.
