GridCoverageReader API



As quoted from their Javadoc, GridCoverageReader interface is intended to

read GridCoverages from the input stream in a sequential order .

Currently there is 1:1 relationship between an AbstractGridCoverage2DReader instance and a coverage. There is no way to deal with multiple coverages.


Suppose you are working against a NetCDF file which contains several measurements like Temperature, Pressure. We can think about a different coverage for each of them.

We aim to deprecate AbstractGridCoverage2DReader in favor of a new AbstractGridCoverageReader which preserves current methods for simpler readers (which allow to access single coverages) but which allows to get geospatial context (like GridEnvelope, GridRange, GridToWorld transformation, CoordinateReferenceSystem) and read access capabilities by coverage name. Current geospatial context getter method won't be changed to grant backward compatibility.
