Service Support Environment – Freely available overarching infrastructure – Permanently hosted and operated by ESA/ESRIN – Facilitates the set‐up of operational services for  Earth Observation – Currently 290 services, 60 providers, 1700  professional and science users

Benefits for Service Providers (SPs) – – – –

Full control over own infrastructure Reduced service set‐up/demo costs Easy re‐use of generic/basic services Combining/chaining of services, etc.

Coherence with INSPIRE, GEOSS,  GMES 25/02/2009

SOSI Project Objectives Verification of SEIS concepts for infrastructure and services – In context of Land Cover Monitoring & Earth Observation – Demonstration of distributed data and processing services – Shared at European and Member States levels

Assessment of SSE w.r.t. suitability for SEIS – Concept, architecture, and technology opportunities  (e.g. available technology for re‐use)

Coherence (jointly assessed in GIGAS project partnership) – – – –

SOSI Services ISO 19119 Service Taxonomy Geographic human interaction services

SOSI Services (INSPIRE service naming, as applicable) SOSI geoportals based on the SSE graphical user interface SOSI spatial data discovery / view / download services

Geographic model/ information management services

SOSI invoke spatial data services (value adding service chains): •For MERIS satellite data spatial and thematic processing •For LC statistics processing (Built-up areas aggregated according to Corine classes)

Geographic processing services – spatial

MERIS satellite data ortho-rectification service

Geographic processing services – thematic

MERIS satellite LC classification service (MEEO solutions) Built-up areas aggregated according to Corine classes (GIS service demonstration example) SOSI service discovery service

Next steps Next steps for SOSI – Service Chaining: Adapt/adopt for next planned Europe‐wide LC generation  (as Fast Track but based on 2009 EO data) – Evolution of SOSI: Recommendation for OGC Pilot ¾ Larger community of Member State representatives  (Invite EioNet, NESIS, …) ¾ Planning for sustained operational use

Next steps for SSE – Enhancements recommended: federated user management and security;  SOAP binding for OGC Web Services (INSPIRE requirement); modernization of  WebMapViewer (e.g. Ajax)
