CEOS Support to GCIAgenda Item 8

GCI Improvement for 2011 GEO Plenary
Major enhancement of GCI decided at 15th GEO ADC (INPE, Brazil, March 2011)
– Demo at next GEO Plenary: Sprint to Plenary - StP
Some specific features to be implemented:– Simplify registration of GEOSS resources – Information on data quality and data access conditions to
the registered datasets (= collections of products)– Increase number of GEOSS resources discoverable
(incl. datasets)– “Easy” access to discoverable EO datasets
Potential contribution of CEOS Agencies
25th CEOS Plenary | Lucca, Italy| 8-9 November 2011
Basic definitions …
Product: elementary informatione.g. MERIS image over Netherlands, 12 Sep. 2002
Collection: group of objectse.g. Monet’s paintings @ Musée d’Orsay
Datasets: collection of satellite products
e.g. MODIS images
Catalog: detailed list of products from one or more collectionse.g. LANDSAT catalog with 2.4 million products
25th CEOS Plenary | Lucca, Italy| 8-9 November 2011
Areas for Potential CEOS Action
To be “easily” discoverable through GCI:
• Collections of products (=datasets) shall be registered either in GEOSS Component & Services Registry (CSR) or in CEOS International Directory Network* (IDN)
• Space Agencies’ catalogues shall be “easily” query-able in parallel– Catalogs may include several collections; – for each collection, lists all individual products of each collection
* = based on NASA Global Change Master Directory (GCMD)

CEOS Response: Datasets Discovery
Integration of CEOS IDN with GCI as multiplied number of resources discoverable through the GEO Web Portal by a factor ~ 100 !!!– discover datasets
CWIC (prototype catalog interface) provides an interface between the GCI and specific EO catalogs at NASA, USGS, NOAA and INPE– discover products within datasets. Parallel queries to all
catalogs
Note that EO catalogs from major European space agencies incl. ESA are being linked via HMA protocol (operational solution – open source S/W available to all)– discover products within datasets. Parallel queries to all
catalogs
Solutions such as HMA, CWIC can perfectly co-exist.
25th CEOS Plenary | Lucca, Italy| 8-9 November 2011
CEOS Response: Datasets Registration
GEOSS CSR: number of CEOS datasets (= collections of products) registered is about 40
IDN: about 7750 datasets (millions of products) out of 20.000+ registered in IDN are marked as “GEOSS Data Core” datasets !!!! – Mainly US Agencies datasets. – Not all datasets ”easily” accessible
25th CEOS Plenary | Lucca, Italy| 8-9 November 2011
Areas for Potential CEOS Action (cont’)
To be “easily” accessible through GCI:
• Datasets access conditions shall follow the GEO Data Sharing Principles as much as possible
• Preferably information on how to access those collections and the individual products they contain, shall be exploitable by machines to avoid /reduce lengthy manual user navigation
25th CEOS Plenary | Lucca, Italy| 8-9 November 2011
CEOS Response: Datasets Access
Providing data policy allows it , the access to individual satellite products from the GEO Web Portal is, most of the time, a manual process – No one-stop-shop– Users have to access products through each individual product
client (one or more per Agency)
At GEO Plenary, demonstration of transparent and “easy” access to products (see demo next slide)– Using EC FP7 prototype tool: GENESI (lead by ESA)
25th CEOS Plenary | Lucca, Italy| 8-9 November 2011
1 collection = 1 dataset
query
All collections
Access to product in 3 mouse clicks …
All products in that collection
Info on individual productindividual product
This demo requires additional information on datasets / products access which is currently neither in IDN nor in GEOSS CSR
25th CEOS Plenary | Lucca, Italy| 8-9 November 2011
Conclusions
Data Access: further coordinated efforts from CEOS Agencies are needed to offer a direct / transparent access to products through the GEO Web Portal incl. access to registered GEOSS Data Core datasets.
Datasets Discovery: large improvement thanks to the recent use of IDN, HMA and CWIC– IDN and HMA are operational and funded, CWIC is
prototype– Space Agencies’ infrastructure is heterogeneous. No
one-size-fits-all solution but only a limited number of technical solutions can be envisaged. Agencies shall share their solutions whenever possible
Registration of datasets: in general good reaction from CEOS Agencies incl. for GEOSS Data CORE

THANK YOU ….

Backup Slides
25th CEOS Plenary | Lucca, Italy| 8-9 November 2011
• Reuse of relevant existing projects (e.g. EC FP7). – Cost and time optimization.– 2 potential candidates for integration into GCI:
GENESI and EuroGEOSS
• Initial focus on about 20 Critical EO Observational Parameters and associated datasets
– Data-CORE and other datasets
