Provide support for ISO Coverages
Possible area of collaboration between GALEON and Oceans IE: serving CF-netCDF encoded coverages via WFS and SOS.
The GALEON Interoperability Experiment is attempting to include a wide range data types among those being served via standard interfaces. The goal is to have each of these data types encoded as CF-netCDF coverages and perhaps served via different protocols.
In general the new process involves the following steps:
) Come to agreement on the fundamental set of high-level dataset categories (e.g., point, station, trajectory, swath, grid) and define extensions to CF conventions for each of those categories.
2) Map the data model for each CF-netCDF extension into the ISO 19123 coverages model.
3) Determine how each CF-netCDF extension and the corresponding ISO coverage type can be expressed as Scientific Feature Types in GML (Geography Markup Language) and relates to the Sampling Feature Types of the OGC Observations and Measurements.
4) Ascertain how each coverage type can be delivered via standard service protocols, e.g.: in GML via WFS, as sampling features via SOS as well as coverages via WCS.
5) The results of these incremental augmentation efforts will be fed into the appropriate standards bodies.
As experts on WFS and SOS protocols, the Oceans IE participants may be interested in experimenting with serving these CF-netCDF encoded coverages via those protocols.
