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.

History

Original motivation to assist UN in improving access to Landsat Global Mosaic data (1975, 1990, 2000) and to SRTM global 90m-resolution digital elevation data (DEM)

Originally referred to as CLASP CEOS Landsat and SRTM Project

Renamed to EO Data Portal Task Team to broaden scope and make idea more attractive to CEOS Plenary

CEOS WGISS/WGCV Meeting Cordoba, March, 2005.4

The CLASP Concept CEOS WGISS to 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.

ICEDS web client

CEOS WGISS/WGCV Meeting Cordoba, March, 2005.7

Visual data in other clients (e.g. ArcGIS)

CEOS WGISS/WGCV Meeting Cordoba, March, 2005.8

View WCS data in customised client

Simple client based on the client/server architecture developed with IDL Code is easily portable via an IDL virtual machine

which is freely available

Allows on-line connection to the ICEDS WCS server

Signed 16-bit data retrieval Display 3D perspective views of SRTM DEM Vertical exaggeration control parameter Possibility to choose desired area by BBox

EODP Homepage Expert users need more than simple visualisation

client

EODP intends to provide comprehensive list of CEOS-member OGC-compliant servers

Future Plans

Continue CLASP software development and data distribution

Interested Agencies to develop their own Portal and data servers

Provide more information on access to OGC-compliant data servers

Develop links with WGCV (presentation by Prof. Muller to follow).
