  • To allow an easy and harmonised access to heterogeneous resources

  • To develop services for data discovery, access, and use establishing and promoting data sharing

  • Facilitate geo-resources sharing

  • Facilitate geo-resources access

  • Contribute to GCI enhancement

Today, the GCI (GEOSS Common Infrastructure) is designed to support only

a limited number of user typologies.


  • Initial set of user communities and multidisciplinary requirements identified by the GEOWOW partners:



  • Requirements from external sources, like projects and Architecture Implementation Pilot (AIP) processes

  • Towards a geowow vision
    Towards a GEOWOW vision

    • A long-term vision for the GCI evolution, in agreement with the IIB.

    • This will include not only components developed by GEOWOW itself, but also external elements.

    Priority functionalities

    • Improved data discovery including results ranking;

    • Easier data access;

    • Interface of GCI components from external clients, including two ways communication;

    • Improved data usability, including harmonization and geoprocessing services;

    • New data registration mechanisms, including support for the GEOSS Data CORE

    • Solutions and tools for user registration authorization authentication including single sign-on.


    • GEOWOW has analysed important key technologies, establishing a pool of solutions and ideas

    • A preliminary analysis has been conducted to map identified requirements to analysed projects (EuroGEOSS, UncertWeb, GENESI-DEC, GeoViQua, Eye on Earth and the current GEOSS Common Infrastructure, …)


    • The landscape of technologies is in continuous evolution architecture flexibility is a key requirement.

    • The design of the GEOWOW Architecture shall therefore follow a modular approach. It shall result in a set of “GCI Evolutions”, i.e. interoperable components that respond to the community needs and are able to fit into the existing landscape, however rapidly this is evolving.

    Usage patterns

    • The proposed architecture will result as flexible as possible and different communities will benefit from it in different manners, according to their needs and their usual working habits.

    Query of heterogeneous observations, products, information

    Semantic enriched search

    Just an example of use case from several usage patterns that will be possible according to user needs

    Satellite data

    In- Situ data

    Tools for geoprocessing

    Interferograms computed from satellite data (either on demand computation or discovery of previously generated products)

    Registration of results

    Preliminary identified components

    • Components for Enhancing Data Discovery and Access including:

      • Result Ranking;

      • Semanticenriched search;

    • Geoprocessing components;

    • User registration components and tools for authentication (user personal information will not be registered at GEOWOW side);

    • Resources Registration facilitators to improve the GEOSS Data CORE availability;

    • Components for enabling community specific clients to access GEOSS resources.

    In a nutshell seamless discovery and access to

    …for all the identified GEOSS users according to different usage patterns…

    … with special focus on GEOSS Data CORE
