Date Thu, 07 Mar 2019 11:17:00 GMT

---------------------------------------

             Summary: GridCoverageResource interface for raster data
                 Key: SIS-444
                 URL: https://issues.apache.org/jira/browse/SIS-444
             Project: Spatial Information Systems
          Issue Type: Task
          Components: Storage
            Reporter: Martin Desruisseaux
            Assignee: Martin Desruisseaux
             Fix For: 1.0


All {{DataStore}} in Apache SIS provides their data as a collection of `Resource`. There is
different kinds of resources; SIS 0.8 already provides {{FeatureSet}} for resources made of
a stream of `Feature` instances (typically geometries associated to some property values).
We need another specialization of resources, {{GridCoverageResource}}, for raster data. Two
key elements of grid coverages are:

* {{GridGeometry}}, which describe the _domain_ of a coverage (e.g. the raster size in pixels
and the geographic envelope).
* {{SampleDimension}} which describe the _range_ of a coverage (e.g. the meaning of values
stored in raster bands).
