  1. Brief Review of INFEO www.infeo.org • INFEO is a distributed system for search of EO and related data • Catalogue Search of INFEO uses CIP profile of Z39.50 • Find collections of interest • Find products of interest • A system of middleware nodes and gateways • Since Feb 2001 INFEO has been operated by ESA • Priority improvements: User Interface and Performances CINTEX 09 May 2002

  2. INFEO Catalogue Search Architecture • INFEO node manage database of collections • GATEWAYS provide access to catalogues (EO and other databases) Main INFEO Node and MCF (at ESRIN) Other INFEO nodes (eg RAL) GATEWAY to EO database GATEWAY to EO database GATEWAY to EO database GATEWAY to EO database ACCESS to GEO servers (e.g. BADC) (e.g. ESA/MUIS) (e.g. NASA/IMS) (e.g. DLR-DFD) (under test) CINTEX 09 May 2002

  3. How to add collections to INFEO • Add a gateway • Describe the collection • Add the collection to INFEO and test CINTEX 09 May 2002

DLR Level-3 data products are based on validated ESA Level-2 products. The GOME Level 3 products are 16 bit quantized, so 65,536 values can be imaged. Since the global thinning of the ozone layer occurs in a range below one percent, 8 bit quantization might be too inexact. If one imaged a range of 100 to 500 DU, the relative accuracy would be ca. 1.56 DU. With respect to the entire range, these would be percentage steps of ca. 0.4, just below the resolution (0.5%) required for detecting thinning of the atmospheric ozone layer.\n\nThe main purpose behind the generation of the rolling three-day synthesis (GL3O3GRC) is to provide a total global view of atmospheric ozone distribution. <TemporalRange> <StartDate>1996-01-01Z <EndDate> </TemporalRange> <SpatialCoverage> <WestBoundingCoordinate>-180 <EastBoundingCoordinate>180 <NorthBoundingCoordinate>90 <SouthBoundingCoordinate>-90 <SensorID>GOME <MissionID>ERS-2 <ThemeKeyword>EARTH SCIENCE>ATMOSPHERE>Atmospheric Chemistry>Ozone CINTEX 09 May 2002

  9. ESA/MUIS Gateway ESA/MUIS Gateway - CIP2.2 - operated at ESA/ESRIN - custom gateway to MUIS servers - 17 collections from earth observation missions s CINTEX 09 May 2002

  10. NASA/IMS Gateway NASA/IMS Gateway - CIP2.4 - being tested at GSFC - custom gateway to IMS servers (GSFC, EDC, JPL, ...) - 12 out of >800 collections configured (work in progress) - NASA investigating INFEO node installation CINTEX 09 May 2002

  11. BNSC/RAL Node, BADC Gateway UK RAL INFEO NODE + BADC Gateway - CIP2.2 - operated at RAL - CIP/ODBC gateway - 1 collection configured • investigating connections to other UK data centres BritishAtmosphericDataCentre CINTEX 09 May 2002

  12. DLR/DFD Gateway DLR Gateway - - connected through IMS server - 6 collections configured - short term action required to attach DLR retrieval manager CINTEX 09 May 2002

  13. Gateway Prospects ... SeaSearch Connection NMA mapping Node IGN Gateway Russian Connection ENVISAT Gateway NeoNet Connection SPOT Gateway? EURIMAGE Gateway? NASDA Node And others ...(including GEO) CINTEX 09 May 2002

  14. (A history of) User Interfaces Simple Search Better Advanced Search -no hiding of CIP - Better Still - new interface based on DLR/EOWEB, ESA/EOLI re-use - pre-operational prototype at http://piglet.esrin.esa.it:8080/eoweb/html/infeo/index.html CINTEX 09 May 2002

  15. DEMO 1 – INFEO new client • Simple product search • Collection and product search CINTEX 09 May 2002
