2. EO Data Portal Aims
To co-ordinate CEOS-member activities in the area of improving access to both global and local EO datasets.
To encourage the use of OGC standards to support the interoperability of data services.
To prototype OGC-based web-services in order to generate Guidelines & Lessons learnt Documents to assist with the implementation of operational systems.
To maintain a EODP homepage containing links to the OGC-compliant data servers of CEOS members.

3. 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

6. 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)

8. The CLASP Concept CEOS Landsat and SRTM Project
CEOS WGISS to assist the UN and FAO in promoting the exploitation of the Landsat and SRTM data by:
Coordinating the deployment of servers hosted by various Space Agencies around the world.
Working with the OGC to accelerate the development of relevant standards and software such as OGC WCS.
Encouraging the development of standards-based software tools and associated web-based services.
Goal to go beyond just display – make data available through OGC Web Coverage Servers

9. Related parallel activities
“Onearth” activity at JPL have made entire 2000 rgb mosaic available via OGC WMS
Different band combinations also available
FAO deploying OGC compliant servers
Liping Di (GMU) planning to host Landsat and SRTM data and make it available through both OGC and GRID interfaces
Google Earth now becoming widespread – but requires very high bandwidth.

10. Integrated availability
Original Schedule
Planned for 2-year project
Some parts gone more quickly, some more slowly

11. ICEDS web client

12. Current Status BNSC funded 2 yr ICEDS Project – ends in Jan 2006
ICEDS achievements
Developed demonstration client
Created Guidelines Document
Begun to talk to potential users in Africa
Begun Landsat data transfer from UNEP(USGS)
Landsat 2000 dataset - 3Tbyte.
Disc transfer not successful
Data to be made available on tape by UN
SRTM already available through Internet download
Related developments:
(GMU/LAITS; Worldwind)
Google Earth

13. Future Plans Continue to work on data distribution
Encourage Agencies and other organisations to develop their own Portal
JAXA adding links to Digital Earth viewer
Provide demonstration to CEOS Plenary 19 ?
