Cordoba, March, 2005


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

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


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


Original Schedule

Planned for 2-year project

Some parts gone more quickly, some more slowly

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)


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 ?
