coverageGeoCoordSystem.xsd Metadata for coverage associated to a referenced or unreferenced geo coordinate system. An extension to the ncML core metadata in order to formalise netCDF metadata useful for GIS interoperability NcML Group, editor S. Nativi Creation: Boulder, Aug 2003; Update: Florence, Dec 2004; Update: Florence, Jan 2005; Update: Prato, Feb 2005 Coordinate System of a Coverage dataset. Dataset coordinate system whose domain is characterized by a geographic description. Such geographic description of the domain is generally useful for catalog service. Coverage dataset is characterized by Grid implicit geometry. Grid dimensions stem from geo coordinate system axes. If geoCS is located, then grid element is sufficient. Otherwise, useful elements are the specialisations: rectified, referenceable and sparse grids. Whether geoDomainLocation is present, Coverage can be a rectified Grid. On the contrary, the appropriate elements is the generalization: Grid NetCDF dataset containing one or more Coverages Extent and geometry information which characterizes the Coverage coordinate system Extent, referenced location and geometry information which characterizes the Coverage coordinate system Grid dimensions stem from geo coordinate system axes. Grid extent depends on dataset dimensions. Reference to netCDF variables whose values are the coverage matrix counts Coverage geometry information: describes the matrix dimension axes. These axes are pointed by the CoordianteAxisRef elements
