Coverage_Processor_for_Cubes Description: This component executes the WCS GetCoverage Query for Cube Data. It Locates the NetCDF-CF file that contains the coverage, then extracts the requested subset and writes that into a NetCDF-CF file.

Term Details
The Coverage Processor is a component that performs two different activities:
- WCS Query Parser. The syntax is checked and parsed into a structured object.
- Subsetter. This component finds the desired coverage and applies filters to read a subset of the data:
- Coverage: Locate the source file.
- Fields: A client querying wind data may be interested in speed and direction, but reject air pressure.
- Bounding Box: restrict response to certain geographical area.
- Time: Default time, One time, list of times, periodic range of times.
- Grid size and interpolation: High resolution data can be interpolated to lower resolution.
- By dimension: Select only one or some wavelengths or elevations.
- Write the result into a NetCDF-CF cube.
Currently there is no formatter, the only supported output is NetCDF-CF. The NetCDF-CF based processor is completely generic for any compatible netCDF-CF file.
