  1. EUMETSAT CMR/CWIC Status Report • CEOS WGISS-46 Meeting DLR Oberpfaffenhofen22-24.10.2018 Uwe Voges (con terra GmbH)

  2. EUMETSAT Collections provided to CMR/CWIC • We updated the list of collections provided for CWIC (incl identifier, links to PN, CMR,…) • Collections were tested and documented https://earthdata.nasa.gov/search?q=acronym.OAS...

  3. EUMETSAT Collections provided to CMR/CWIC • Most collections are already in CMR/IDN • Some are yet missing: • acronym.SL_2_WST___.satellite.S3A,S3B.tmls.NR.fileid.EO.EUM.DAT.SENTINEL-3.SL_2_WST___NRT • acronym.SL_2_WST___.satellite.S3A,S3B.tmls.NT.fileid.EO.EUM.DAT.SENTINEL-3.SL_2_WST___NTC • Some are declared wrong • ...EO.EUM.DAT.MULT.GBLSIED In CMR: ...GBLSIE • ...EO.EUM.DAT.MULT.GBLSITY In CMR: ...GBLSIT • ...EO:EUM:DAT:MULT:GBL-LR-SIDR In CMR: ...GBL-LR-SID

  4. Migration DIF9 -> DIF10 • We´re using the XSD for DIF Version 10.2 b: 10_x_dif_v10_2 • Important changes related to DIF9: • Related_URL now mandatory • DataCenter -> Organization • Parameters -> Science_Keywords • Ancillary_Keyword -> uncontrolled words or phrases used to further describe a data set • Platform/Instrument • Spatial_Coverage redefined • Dataset_Progress (R), Project (R), Metadata_Dates (R) • Few updates done after first DIF10 delivery (email M. Morohan 25.9): • xml schema location added • Changed <Organization> fields (e.g. for OSI SAF and EUMETSAT) • Added for Platform/Instruments the LongNames. • …

  5. Provision of EUMETSAT Collection MD to CMR/CWIC • Workflow for IDN/CWIC metadata (DIF10) provision at EUMETSAT: • Assignment of EUMETSAT collections to CMR/CWIC • We manage an Excel sheet (see before) where we list all collections assigned to CWIC (and FedEO). • From time to time a review takes part: is collection list up to date, what has to be added or dropped. • Tagging CWIC collections in New PN • Aligned with Excel sheet we tag CWIC collections (see right) • Export DIF-10 metadata for CWIC collections • New PN Administrator provides a Metadata Export Function • ..lets filter metadata for CWIC by providing the filter statement: useLimitation="CWIC…." • Use eum2dif XSLT upon export • Add collection identifier as options for parameter parentIdentifier to OSDD of CWIC/EOPOS adapter! (not yet automated) • Send DIF-10 metadata to Michael Morohan :-)

  6. EUMETSAT Collections for CMR/CWIC • Search is possible on all collections stored in CMR/IDN • Problem: e.g. the maximal temporal extent where products are available could only be requested via the collection MD

  7. EUMETSAT OpenSearch-EO (1.1) Interface - OSDD • OpenSearch-EOP interface adapted to V 1.1 (backwards compatible!) • http://eoportal.eumetsat.int/os-description • OSDD (minor changes): • shortName max 16 chars • query example: minimal mandatory parameters included • added CEOS-OS-BP-V1.1/L1 Tags-Element

  8. EUMETSAT OpenSearch-EO (1.1) Interface - Request • Search Operation • Treat as equivalent: • optional parameter left empty (key present but value absent) • key/value pair for the optional parameter removed (both key and value are absent) • Exceptions codes aligned with OpenSearch-EO 1.1 • Request • use startIndex over startPage • all string based search parameters follow the default behavior: "exact search“ • Examples: • http://eoportal.eumetsat.int/eopos?dtstart=2015-09-04T00:00:00Z&pI=urn:ogc:def:EOP:EUM:acronym:OAS025:fileid:EO:EUM:DAT:METOP:OAS025&dtend=2015-09-06T15:00:00Z • http://eoportal.eumetsat.int/eopos?bbox=-70.00,10.00,-20.00,13.00&dtstart=2015-09-04T00:00:00Z&pI=urn:ogc:def:EOP:EUM:acronym:OAS025:fileid:EO:EUM:DAT:METOP:OAS025&dtend=2015-09-06T00:00:00Z&c=2

  9. EUMETSAT OpenSearch-EO (1.1) Interface - Response • Feed • added SpecReference to atom:feed • georss:box • query example: all mandatory parameters included (TBD) • ! Here we had a problem with not closing a gml:LinearRing -> removed ! • Entry: • type (genre) of the entry (here: http://purl.org/dc/dcmitype/Dataset) • GeoRSS Simple” (Polygon) • csw:GetRepositoryItemResponse • OGC EOP O&M (10-157) • ATOM entry of dataset (aka collection) • EUMETSAT USC Order Client • EUMETSAT EO Download Service

  10. Testing EUMETSAT EOPOS with CWIC Smart Client • Testing with CWIC Smart Client not more possible: • http://api.echo.nasa.gov/cwic-smart/ • Added OSDD endpoint, e.g.: • http://eoportal.eumetsat.int/os-description • Not more possible as a collec- tion endpoint is needed ? • I also tried: http://rs211980.rs.hosteurope.de/eo-pn-adapter/os-description.xml • Doesn´t work..

  11. Questions, future developments • Questions: • Are the CWIC OpenSearch Adapters updated to OGC OpenSearch-EOP 1.1 : • 13-026r9: offerings, GeoRSS Simple, error codes, links, parameters, ranges & sets, … • Are there plans on using GeoJSON binding ? • Prospects for further developements • When OLDA becomes operational -> OLDA collections may be provided via separate OpenSearch endpoint • Currently only one collection overlapping (EO:EUM:DAT:METOP:GLB-SST) -> s. EUMETSAT Collections for CWIC_IDN and FEDEO V3_1.xlsx

  12. EUMETSAT OpenSearch (EOPOS) Interfaces • OSDD / URL templates: • HE – pre-testing: • OSDD: http://rs211980.rs.hosteurope.de/eo-csw-umarf/servlet/os-description • URL Template: http://eumetsat.eggits.net/eo-csw-umarf/servlet/eopos?pi={eop:parentIdentifier}&amp;pw={startPage?}&amp;si={startIndex?}&amp;c={count?}&amp;bbox={geo:box?}&amp;dtstart={time:start?}&amp;dtend={time:end}&amp;iqd={eop:productQualityStatus?} • Sample: http://rs211980.rs.hosteurope.de/eo-csw-umarf/servlet/eopos?dtstart=2016-09-04T00:00:00Z&pI=urn:ogc:def:EOP:EUM:acronym:ASCSMR02:fileid:EO:EUM:DAT:METOP:SOMO12&dtend=2016-09-15T00:00:00Z • VAL/OPE – testing/operationell: • OSDD: http://(v)eoportal.eumetsat.int/os-description • URL Template: https://(v)eoportal.eumetsat.int/eopos?pi={eop:parentIdentifier}&amp;pw={startPage?}&amp; si={startIndex?}&amp;c={count?}&amp;bbox={geo:box?}&amp;dtstart={time:start?}&amp;dtend={time:end}&amp;iqd={eop:productQualityStatus?}" • Sample: http://(v)eoportal.eumetsat.int/eopos?dtstart=2010-07-04T00:00:00Z&pI=urn:ogc:def:EOP:EUM:acronym:OASW012:fileid:EO:EUM:DAT:METOP:ASCAT12&dtend=2010-08-11T15:00:00Z
