> 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).
