EUMETSAT CWIC Status Report
CEOS WGISS-42 Meeting ESA/Esrin Frascati Uwe Voges (con terra GmbH)

EUMETSAT Collections We provided new collections to IDN / CWÍC
collections were tested and documented we provided DIF metadata for IDN provided Sentinel-3 dataset metadata and let it register with CEOS IDN

EUMETSAT OpenSearch (EOPOS) Interface
Updated the following links in EOP search interface (EOPOS) responses: USC (EUMETSAT Order) client EO Download Service (OGC ) Impl: Specification defines HTTP/GET/KVP service for downloading EO products provides two operations: GetCapabilities: Service metadata. GetProduct: Download a product with its product URI. Use case implemented -> On-demand download: option is used if requested product is available in off-line archive … …and download server needs time to retrieve and restore it to online availability. client polls server: if product is not ready yet, it sends a response with a “retry after” period that tells the client when to try again. To unblock the order (for first time) -> the user has to leave his “user details”. User has to provide his and the system verifies if the user details are already known. If not he has to provide some information (see right).

EUMETSAT OpenSearch (EOPOS) Interface
Random tests to check consistency between temporal coverage of DIF metadata with provided products -> problem resulted from restrictions on VAL Ignore large spatial filter in EOPOS workaround implemented: BBox ignored if larger than half of the earth (size is configurable). EOPOS now enabled on EUMETSAT OPE server. We have an issue, such as CWIC tries twice a day a search from 1977 until today for each collection. It seems that when the search takes too long, a probe on tomcat health triggers a restart of the server on our VAL system. it would be better if CWIC issues queries for time periods (inside start / end date of collection definition) We return at max records (i.e. about 100 days for MSG data, 200 days for MTPO data and 680 days for Metop data). We could increase the number to make sure that 0.5 year is searchable MSG data. CWIC could than always iterate through 0.5 years intervals. There is a count(*) function on our ToDo list.

Testing EUMETSAT EOPOS with CWIC Smart Client
Testing with CWIC Smart Client: Added OSDD endpoint, e.g.: description Under Pi there is a list of collections we provide in the OSDD Question: how to use IDN collections Select Pi, fill details,..., Search...

EUMETSAT OpenSearch (EOPOS) Interfaces
Questions from our side: What are the plans for getting an operational site (and the roadmap). How is the workflow Dataset search from IDN – Granule search in CWIC Have you got any monitoring/reporting statistics of the usage of the current system (Access per month etc). Do you want to support OGC OpenSearch-EOP 1.0 and the planned OGC OpenSearch-EOP 1.1 with GeoJSON binding ? Would NOAA/NASA want to be part of the SWG and support this ?
