netcdf-coverage.xsd Content metadata for encoding coverage objects, as well as geospatial extent and CRS related objects, starting from ncML-CS elements and building on GML grammar. An extension to the ncML core metadata in order to formalise netCDF metadata useful for GIS interoperability NcML Group, editor S. Nativi, L. Bigagli Creation: Prato, July 2005 Modified: - v0.7.2 G.Villoresi, Prato, 13-Oct-2005 (coordinateAxisRefRef moved from keys to keyrefs) - v0.7.3 G.Villoresi, Prato, 31-Oct-2005 (refactoring of scalarRangeSet's asciiData and binaryData in embeddedData) Define a set of geospatial coverage objects, generated from a netCDF dataset. It is a specialization of the netcdfType element: it defines constrains to have both CS and CS transformation uniquely named. Set of coverage objects stemming from a netCDF dataset Constrained to: Grid domain axis names point to axes names of the linked coordinate system. (not yet fully implemented). It models only coverage which stems from netCDF variables (one or more), whose shape can be fully represented as a coverage grid domain. Only axes order can be redefined. Describe the geospatial and temporal coordinate system which defines the coverage domain. Coverage geospatial and temporal domain is fully localized according to coordinate reference systems (CRSs) This element extends the coordinateSystem element by adding missing information about the localization aspect of the coordinate system. Spatial envelop of coverage domain Vertical extent of coverage domain Temporal extent of coverage domain Link a coordinate system element declared in the netCDF dataset. The linked coordinate system describes the axes of the coverage domain. Defines the set of variables which constitutes the coverage range set. Set the order of the netCDF variables associated to the optional _ScalarValueList elements. Describe the geographicl extent of the coverage domain. That is useful for cataloguing and browsing purposes. Coverage dimensions stem from netcdf coordinate system axes. Coverage function order is +y+x; sequence rule is linear. Describe the geospatial coordinate system which defines the coverage geospatial domain. Coverage geospatial domain is fully localized according to a coordinate reference system (CRS) This element extends the coordinateSystem element either by adding missing information about the geospatial localization aspect of the coordinate system, or by introducing a specific CRS and mapping the coordinate system to it. Describe the geospatial localization of the geospatial coverage domain determined by the linked coordinate system element. Describe the spatial and temporal extent of coverage domain
