SPACEBEL has developed several systems related to the distribution
of Earth Observation (EO) products and provision of related
services including:
The
Service Support Environment (SSE) is a Web-based environment
providing an EO data access layer allowing an easy integration
of data catalogues (SPOT Image, MUIS, etc.) and EO services
using open standards such as XML, BPEL, WSDL and SOAP
etc.
PROMISE
(PRoduct Ordering System for MultIple Satellite Environment)
is a system to handle the request for products from the
customers in a multi-mission environment which we have
realized for ESRIN.
We
have a large experience with service-oriented architectures
(SOA), Web services standards from organisations such as
W3C, OASIS and OGC and interoperability aspects in particular
related to Earth Observation ground segments. Our main developments
are based on Java J2EE technology.
The
SSE is operational and an integral part of the ESRIN
EO Ground Segment Architecture. Click on the right

SPACEBEL is an OGC (Open Geospatial Consortium)
Technical Committee member and has applied OGC specifications
in many of its projects.
Projects
and References
HMA-T
ESRIN has awarded the HMA Testbed (HMA-T) Project
in January 2007 to a Consortium lead by Spacebel.
HMA-T is one of the GMES Preparatory Study projects,
has a duration of 30 months, and aims to support the
adoption and compliance testing of HMA-related protocols
and maintain a permanent HMA testbed hosted by ESRIN
which is based on the ESA SSE. As part of this project,
SPACEBEL is also integrating various catalogues in
the testbed which are based on the OGC CSW ebRIM Application
Profile, in particular the extension package for Earth
Observation OGC 06-131.
HMA-I
In
the Heterogeneous Missions Accessibility Interoperability
(HMA-I) project for ASTRIUM-UK and ESRIN, SPACEBEL
developed the prototype of the Data Access Integration
Layer (DAIL) which will provide access to Earth Observation
catalogue, ordering and programming interfaces of
various ground segments from ASI, CNES, DLR, ESA,
CSA, Eumetsat etc. The prototype was developed as
a Service Oriented Architecture (SOA) based on the
ESA SSE. SPACEBEL also prototyped a federated identity
management solution based on SAML and ws-security.
As part of the project, Spacebel also supported ESA
to submit the resulting HMA ICDs to the OGC.
Flexsys
As part of the Flexsys Project for ESRIN lead by VITO
(Belgium), SPACEBEL designed and developed in 2006-2007
the Flexsys "product delivery subsystem", i.e. a component
running on the VITO infrastructure that exposes to the
outside world an HMA-compliant OGC CSW EO Application
Profile (OGC 06-079) catalogue and ordering (OGC 06-141)
Web service interface and communicates with the internal
VITO back end of the Flexsys product delivery system
(VUS). This component was implemented using J2EE and
runs on a BEA Weblogic application server.
OGC
FEDEO
SPACEBEL
participates to the Federated Earth Observation (FEDEO)
interoperability pilot (august-september 2007) setup
jointly by ESA and the OGC. The FEDEO pilot uses the
SSE as interoperability platform.
COMU
CoMu is a Technology Research Program (TRP) project
for ESRIN by a Consortium lead by ASTRIUM-F and also
consisting of SPACEBEL and Spotimage. CoMu defines and
prototypes a multi-mission planning solution enabling
users to submit orders on a thematic basis without having
to know exactly the specific capabilities of each available
EO system. This solution answers to the user needs by
optimizing the use and complementarities of the existing
sensors capabilities. SPACEBEL is responsable for the
development of the prototype's interoperability layer
which is implemented with Web services and BPEL technology.
It uses the OGC Sensor Planning Service profile for
Earth Observation (OGC 07-018).
COPS-B
SPACEBEL is part of the Consortium lead by GIM which
implements the COPS-B (Cooperating EO Sensors) project
for ESRIN. In this project, the benefits and complementarity
of data from Earth Observation sensors and in-situ
sensors will be demonstrated. The project makes
extensive use of OGC Sensor Web Enablement (SWE)
specifications such as Sensor Planning Service and
Sensor Observation Service. SPACEBEL is responsable
for a large part of the prototype implementation,
which is based on the SSE Framework, including the
BPEL workflows accessing the various SWE services.
FP6
SANY
The SANY (Sensors ANYwhere) integrated project focuses
on interoperability of in-situ sensors and sensor
networks. The SANY architecture will provide a quick
and cost-efficient way to reuse data and services
from currently incompatible sensor- and data- sources.
SPACEBEL is responsible for the Sensor Fusion and
Decision Support subproject and will implement a decision
support infrastructure (based on SSE) that provides
discovery and access to OGC Sensor Web Enablement
(SWE) and SANY services.
SPACEBEL is responsible for the InterRisk system architecture
design. The InterRisk system will provide access to the
InterRisk services for environmental risk management in
marine and coastal areas of Europe and is based on a service-oriented
architecture (SOA) implemented with W3C, OASIS and OGC
standards. SPACEBEL is also in charge of developing the
interfaces with the InterRisk ontologies.
BOSS4GMES
(Building Operational Sustainable Services for GMES)
aims to provide the technical, financial and contractual
foundations for the transition of GMES from a concept
to an effective, operational environment. SPACEBEL participates
to the BOSS4GMES project. We contribute to the selection
and development of upgrades for service production and
analysis of infrastructure components.
The
objective of the ESIT (Enhanced Service Integration
Technology) project (2005-2008) lead by SPACEBEL was
the further technological evolution of the ESA SSE.
As part of the project, support for additional standards
was implemented (OGC WFS, OGC WCS, OGC CSW, OASIS
UDDI, IETF LDAP etc.), support for human BPEL workflows
for authorization was integrated and data dissemination
via the ESA Data Dissemination System (DDS) via satellite
multicast was added. Also an interface with the ESA
Grid Processing On-Demand infrastructure (G-POD) was
implemented to provide access to the IMERIS Grid processor
from the SSE. To demonstrate the scalability of the
SSE, it was also deployment in Dakar (Senegal) at
the CSE to provide access to local services. Finally,
as part of ESIT, SPACEBEL participated to the OGC
interoperability testbeds OWS-3 and OWS-4. The results
from these activities which included BPEL workflow
developments on the SSE accessing services compliant
with the OGC specifications WCTS and WCS are available
as documents OGC 05-140 and OGC 07-008 from the OGC
Web site.
SSE
The
Service Support Environment (SSE) is an overarching
infrastructure facilitating the set up of open operational
services for Earth Observation (EO) in Europe. The
SSE allows the integration of a wide range of heterogeneous
EO and GIS services including catalogues of products.
MASS-ENV
(Multi-Application Support Service System Environment)
is an Earth Observation Project funded by the European
Space Agency (ESRIN) and implemented by an international
consortium consisting of SPACEBEL (Prime Contractor),
Intecs and GIM. Its main objective is the further
evolution of the SSE (Service Support Environment)
infrastructure. As part of the project, also a catalogue
interoperability experiment was setup (INCAS) with
ESA and Spot Image to use Web services (EOLI-XML)
and BPEL to implement cross-catalogue search capabilities
in the SSE.
The
Multi-Application Support Service System (MASS) is
a pilot system providing can e-Business Portal and
virtual market place for Earth Observation services
and products. The MASS system was the initial version
of the ESA SSE (Service Support Environment).
