The Picture
ESA/FAO GEOPortal (1)
• A gateway to Global Earth Observation data, in support of
all 9 SBA, developed by ESA in collaboration with FAO.
• Currently operational and available on line at the link:
http://www.geoportal.org.
• One of the three portals developed in response to a set of
requirements from the GEOsec for the implementation of a
GEO Web Portal serving the GEO User Community.
• Part of the GEOSS Common Infrastructure currently in the
Initial Operational Capability phase.
• Based on Open Source components, it can be freely
installed and configured at GEO members’ premises.
– It can be configured to create for example a Portal for a specific
community.
ESA/FAO GEOPortal (2)
• Single point of access to information, which is linked from
various logically related Internet based applications and is
of interest to the GEOSS user community.
• It allows to search and discover services:
• It complements Community Portals and other Portals
operated by GEO Members and Participating Organizations
and does not belong to any single member or organization:
– Community portals should provide user interfaces for specific
communities and as such should act as clients to specific services.
ESA/FAO GEOPortal
Services
• Based on the GEO recommended standards and following the
Geospatial Portal Reference Architecture of the OGC the GEOPortal
provides a variety of services:
– Geospatial Portal Service providing interfaces to users for viewing,
discovering data, information & services available in GEOSS.
• Based on liferay opensource, integrating/displaying services via
JSR168 portlets
– Browse through a comprehensive directory of components and service
providers.
– Showcase datasets and services
• Directory based on GeoNetwork catalogue
– Portrayal Viewer Service allowing the display and handling of maps and
context information from various sources through WMS services.
• Intermap opensource WMS client
– Retrieval of Earth observation education, training and capacity building
resources.
– Syndication of information feeds onto Globe
• GeoRSS feeds
– Interfaces to Catalogue Services of the GEOSS Clearinghouse, allowing
distributed catalogue search in an interoperable manner.
– Integration of new services via workflow tools
How to access data (1)?
• Example: User searching for Floods data – Data Provider
How to access data (2)?
• Example:
through the
FedEO
clearinghouse
How to access data … future … via
clearinghouses and workflow
Compusult clearninghouse
USGS clearinghouse
ESRI clearinghouse
ESA-FAO GEOPortal
Interfaces within GCI
• With GEOSS Clearinghouses:
– Tested during the AIP pilot 2007 through a catalogue client.
– GEOSS Clearinghouses Interfaces (OGC CSW 2.0.2 standard) should be
made available by the providers during GCI IOC for further testing activities
with the GEO Portals for the full functional scope of the elements in order
to ensure interoperability of the developments made by different providers.
• With Registries:
– Actually implemented in the ESA/FAO GEOPortal.
– Feedbeck from GEOSec to provide more “graphical” interface (e.g. logos)
means registries don’t provide sufficient information to be presented in the
GEOPortal and additional info is routinely added for new registered and
non registered components/services (content management).
– Taxonomies for components within registries are poor and so enhanced
when harvesting information from registry
– Automated harvesting can be implemented only when last update available
and a good eye to the quality of registrations
Next steps: ESA
Participation to AIP Phase 2
• Proposal submitted in cooperation with several partners,
aiming at augmenting the GEOSS Common Infrastructure
(GCI) and at supporting the current GCI IOC phase.
• Three different contributions.
1. GEOPortal in cooperation with FAO.
– Maintenance of the current capabilities and functionalities (both
operationally and in terms of content management).
– Addition of new functionalities or improvement of the available ones.
– Consolidation of interoperability and interfaces with the other GCI
components (e.g. GEOSS Clearinghouses).
– Feedback and needs from GEOSS User community, IOC Task Force
and GEO Secretariat will be the main driver for the evolution of the
GEOPortal.
Next steps: ESA
Participation to AIP Phase 2
2. FedEO EO Community Clearinghouse in cooperation with
Eumetsat, International Charter “Space and Major Disasters”,
CNES …..
– Allows distributed catalogue search of EO data and products
using the HMA interoperability protocols defined for GMES
and currently OGC best practises and standards.
– Interface with the GEOPortal allows to provide users with full
metadata (high quality).
– Data ordering/download will be possible in future (respecting
data policies).
– Several EO mission owners over the world will be
implementing the HMA interfaces (GMES, now Kopernikus).
First implementations started.
– Main activities will be to improve and consolidate the
prototype developed in the AIP 2007 FedEO initiative and to
increase the number of EO catalogues accessible through it.
Next steps: ESA
Participation to AIP Phase 2
3. SSE – Workflow, Conformance Testing and Test Environment.
– Workflow Management Engine and Service Test Facility for
conformance/compliance test of data and models to ensure
proper and interoperable use of GEOSS components and
services in applications and interfaces using the HMA standards
consolidated in the framework of the AIP 2007 FedEO initiative
and the OGC conformance testing.
– Support the creation of new services and to test interfaces (for
catalogues, orders, processing and access to the data).

Conclusions
• As part of the GCI IOC, the ESA/FAO GEOPortal already
constitutes a main access point to worldwide information on
Earth Observation capabilities and services.
• ESA proposal for AIP consists of an environment where:
– New GEOSS services can be built and GEOSS components can be
tested with respect to a set of consolidated HMA and OGC standard
based interfaces.
– Access is provided to catalogue services with the standard interfaces.
– Discovery of GEOSS resources is provided to the GEOSS User
community.
• Continuing work with Open Source components to compliment / upgrade
GEOPortal
• ESA willing to work with all scenarios / SBAs to showcase results and
look for common goals
