− | == Capabilities Processor ==
| + | [[AQ Infrastructure]] |
− | | |
− | This component creates the standard XML documents for WCS and WFS services.
| |
− | | |
− | It operates on Metadata and data configuration. From Metadata the capabilities document gets Title, Abstract, Keywords, Contact person etc... From data configuration the processor gets full information of each coverage.

− | == Coverage Processor ==
| |
− | | |
− | The Coverage Processor is a component that performs three different activities:
| |
− | | |
− | * WCS Query Parser. The syntax is checked and output is binary object of all the query elements.
| |
− | * Subsetter. This component finds the desired coverage and applies filters to read a subset of the data:
| |
− | ** 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,elevations,locations
| |
− | * Formatter. The binary data is returned in desired format. Currently supported are NetCDF-CF for cubes and CSV for points.
| |
− | | |
− | NetCDF-CF based processor is completely generic for any compatible netCDF-CF file.
| |
− | | |
− | SQL processors can be either configured to supported DB schema types, or custom written for esoteric databases.
| |
− | | |
− | By writing a custom subsetter, anything can be used as a data source.
| |
− | | |
− | == Cube Configuration ==
| |
− | | |
− | Programmed instructions for the framework how to access data. This includes but is not limited to
| |
− | | |
− | * For Cube Coverages:
| |
− | ** Automatic: Information of variables and dimensions extracted from netCDF-CF files.
| |
− | ** Manual: Hand-edited python dictionaries describing the netCDF files, their variables and dimensions.
| |
− | | |
− | | |
− | * For Point Coverages:
| |
− | ** Hand-edited python dictionaries describing Names and Columns of Location and Data tables.
| |
− | ** Custom modules for databases that are too esoteric configure in pure declarative manner.
