Land Monitoring Network Services based on international geospatial standards: SOSI and geoland2/SDI Projects

Figures & data

Table 1. Sources of standards requirements for g2/SDI and SOSI.

Programme/Project	Explanation
INSPIRE	Directive 2007/2/EC of the European Parliament and Council establishing the Infrastructure for Spatial Information in the European Community. Normative implementing rules and informative guidance documents on the aspects of metadata, interoperability, network services, data and service sharing are or will be adopted.
GEOSS	Global Earth Observation System of Systems, intergovernmental programme; core architecture in alignment with Open Geospatial Consortium® (metadata/catalogue) standards.
GMES – HMA	European Global Monitoring for the Environment and Security initiative; including Harmonised Access to heterogeneous EO satellite Missions.
OGC	Open Geospatial Consortium® leading the development of standards for geospatial and location based services.
GIGAS	Support Action to the European Commission (EC) for identification and definition of needs to enable a full integration of INSPIRE, GMES and GEOSS architectures.
ISO/TC 211	Technical Committee under the International Organisation for Standardisation responsible for digital geographic information; issues International Standards, Technical Specifications and Technical Reports (encoding, metadata, services, etc.).
CEN/TC 287	TC under the Comité Européen de Normalisation for digital geographic information in Europe; close cooperation with ISO/TC 211 to avoid duplication.

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)
Geographic system management services	SOSI services discovery service
	SSE services registry service
	SSE rights management
Geographic processing services – temporal	None
Geographic processing services – metadata
Geographic communication services
