Which needs for an European information distribution infrastructure ?

Market place model confirmed : data providers + value adders +

customers

Information packages defined as specific end products :combining EO + GIS + statistical

information + text + HTML

Needs for meta-information but also information access.

From technology driven market...

...to customers or end users driven market.

Which needs for an European information distribution infrastructure ?

2 end users or customers types :Experts (use specific tools for EO and GIS information

processing).Decision makers (the information is the end product which

helps the decision-making process)

and intermediate level value adders.

No real services distribution. Based on a complex protocol Z39.50. Not suitable for VA (no processing). No on-line data retrieval.

+

Homogenous access to catalogues. Full syntactical and semantic interoperability for EO.

US initiatives : competition or synergy

IMS - NASA development :Best deployed operational infrastructure.But insufficient interoperability and obsolete technology.

OpenGIS - developed by the OGC :Aimed at defining a “Comprehensive specification of software

framework for distributed access to geodata and geoprocessing resources”.

“Specification independent of distributed computing platform”.“Universal open Geodata Model”.

Risk : too ambitious to build an operational infrastructure ?US industry leadership ?

Doubts : usable basis for Value Adders ?

Strategies and opportunities for Europe

Priorities :Include the VA in end-to-end servicesSpeed-up the convergence between EO,

GIS and other information sourcesProvide actual information access

Possible paths :1) Follow Opengis behind US (European leadership ?)2) Develop an European model built on gained experience.3) Promote a mixed approach partly including Opengis

components and specifications (preferred for export market and world-class competitiveness).

Opportunities : 5th framework programme and IST.Develop on-line geoinformation through new projects.
