Coverage function defining mapping of coordinate to value position in grids (simplified from GML). The envelope around a coverage is defined by the lower and upper bound of each axis, respectively... A name list is an ordered sequence of whitespace-separated names... The DomainSet describes the "direct positions" of the coverage... The RangeType element describes the structure and semantics of a coverage's range values... The RangeSet lists a value for each of the coverage's direct positions... A partition describes how a coverage... Position/value pairs resemble (possibly n-D) coordinate / (possibly) composite) value pairs... Direct position points resemble n-D coordinates... The metadata element is a container of any... A GeneralGridCoverage is a specialization of AbstractCoverage where the DomainSet is given by a GeneralGrid; its grid axes can be of different types (non-referenced, regular, irregular, algorithmic, etc.). A coverage whose domain set is given by a grid defined through a SensorML 2.0 transformation model, represented by a TransformationBySensorModel element. In a MultiPointCoverage (i.e., point cloud) the DomainSet consists of a MultiPoint, i.e.: a collection of points. A MultiPoint consist of a list of arbitrary direct positions (normally not aligned on a grid). By using the CIS direct position concept instead of GML, non-numerical coordinates (such as date and time stamps) are possible. In a MultiCurveCoverage the DomainSet consists of a MultiCurve (enforced via schematron rule). In a MultiSurfaceCoverage the DomainSet consists of a MultiSurface (enforced via schematron rule). In a MultiSolidCoverage the DomainSet consists of a MultiSolid (enforced via schematron rule).
