Use Case Definition
The AQ cluster has a fundamental need for a set of CORE web services that allow meaningful user-access to satellite data. These services include:
- Data access by space-time-parameter query on granules
- Subsetting that clips the data to user-specified BBOX
- Mosaicing that splices granule mosaic into a coherent dataset
The proper chaining of these services results in a higher order service, WCS, that returns the requested satellite data for the BBOX, Time, Parameter. Not more not less. Such a WCS service was in fact used in the Web service chaining experiment. Extending that service to return numeric satellite data (not just images) is the goal.
