  1. EO Data Portal Task Team Overview Presentation to WGISS & Subgroup Meeting Cordoba, March, 2005 Wyn Cudlip BNSC/QinetiQ wcudlip@space.qinetiq.com

  2. History • Original idea to improve access to Landsat Global Mosaic data (1975, 1990, 2000) and to SRTM global 90m-resolution digital elevation data (DEM) • Sometimes referred to as CLASP • CEOS Landsat and SRTM Project • Plan to go beyond access to rgb data: use OGC WCS for access to the Landsat and SRTM data • Renamed To EO Data Portal Task Team to broaded scope and make idea more attractive to CEOS Plenary

  3. EO Data Portal Activities EODP TT EODP homepage Other initiatives e.g. Digital Asia WGCV Test Sites Other initiatives Global datasets USGS Coverages CLASP Onearth JPL/NASA ICEDS GMU/LAITS Visualisation WorldWind AJAX/OGC Other datasets

  4. EODP Homepage • Links to: • CLASP • OGC compliant servers page • Global datasets • USGS Coverages map • WGISS Menu ?

  5. OGC Compliant Servers Page • Expert users need more than simple visualisation client • EODP intends to provide comprehensive list of CEOS-member OGC-compliant servers • Provide links to • Service introductory webpage • Client for viewing data • Server address (for GetCapabilities) • http://wgiss.ceos.org/eodp

  6. Example EODP OGC-Server Page • BNSC • ICEDS (SRTM 90m, Landsat5 mosaic(1990) + links to other servers) • Info: http://iceds.ge.ucl.ac.uk/ • Viewer: http://iceds.ge.ucl.ac.uk:8080/viewer/iceds/index.html • Servers: • http://iceds.ge.ucl.ac.uk/cgi-bin/wms?map=wms.map&SERVICE=WMS&REQUEST=GetCapabilities • http://iceds.ge.ucl.ac.uk/cgi-bin/wcs?map=wcs.map&SERVICE=WCS&REQUEST=GetCapabilities

  7. The CLASP Concept • CEOS WGISS assist the UN and FAO in promoting the exploitation of the Landsat and SRTM data by: • Coordinating the deployment of data mirror sites hosted by various Space Agencies around the world. • Working with standards bodies (e.g. the OGC) to accelerate the development of relevant standards and software (particularly OGC WCS). • Encouraging the development of standards-based software tools and associated web-based services. • Phased development over two years, starting with simple map display capability, leading eventually to chained services that can be tailored for specific applications. • Subsequent long-term service sustained by the Space Agencies concerned. • 11 CEOS Agencies already shown an interest in being involved. Eodp mailing list set up. • Improved access to SRTM is a GEO 2-yr objective

  8. Related parallel activities • “Onearth” activity at JPL have made entire 2000 rgb mosaic available via OGC WMS • http://onearth.jpl.nasa.gov/ • Different band combinations also available • FAO deploying OGC compliant servers • EoGeo.org created “Landsat Interest Group” and are working with the Internet Archive who may be prepared to host entire dataset. • Liping Di (GMU) planning to host Landsat and SRTM data and make it available through both OGC and GRID interfaces

  9. Original Schedule • Planned for 2-year project • Some parts gone more quickly, some more slowly Concept Presentation Progress Presentation Final Presentation CEOS Plenary 2004 2005 WGISS/ Subgroups Project Approval Initial WMS Deployment Initial SRTM availability WCS Terrain View Integrated availability

  10. Current Status • BNSC funding ICEDS Project • ICEDS year 1 completed • To explore the use of OGC Servers, WCS in particular • Developed demonstration client • Created Guidelines Document • ICEDS year2 • Further software development • Client: 3-D viewing, blinking etc • Use-case development • Begun Landsat data transfer from UNEP(USGS) • Landsat 2000 dataset - 3Tbyte. • Shipped 500Gbyte disc to USA and back – not very successful • Data to be made available on tape • SRTM available through Internet download • Related developments (GMU/LAITS; Worldwind)

  11. Future Plans • Continue with software development • Continue with data distribution • Interested Agencies to develop their own Portal • JAXA to add links to Digital Earth viewer • Work with parallel activities to establish coherent development plan. • Provide demonstration to CEOS Plenary 19 ?
