GEOSS

The Global Earth Observation System of Systems (GEOSS) is an initiative lead by the Group on Earth Observations (GEO) to link together already existing observation systems in the service of several “Societal Benefit Areas” including biodiversity and ecosystems.

The GEOSS Common Infrastructure (GCI) allows the user of Earth observations to access, search and use the data, information, tools and services available through the Global Earth Observation System of Systems.

EU BON will be integrated with GEOSS through the GCI using its set of core services which consists of next elements:

In the proposed GEOSS architecture, EU BON will, at a minimum, act as a data provider. It will be exposed to the GEOSS Component and Service Registry so that the GEOSS Clearinghouse can catalogue the information and provide access to EU BON metadata via an API, e.g., based on the standard OGC CSW 2.0.2.

The GEOSS Component and Service Registry (CSR) is similar to a library catalogue. Resource providers of governments and organisations could register their resources in CSR through providing essential details about the name, contents, Earth observation vocabulary, standards and special arrangements (if any) of their contribution. This assists the GEOSS Clearinghouse, and ultimately the user, to identify the GEOSS resources of interest.

CSR is linked to the GEOSS Standards and Interoperability Registry, a collection of standards and community practices that are nominated through a registration process by GEO individuals. Currently, there are more than 290 standards registered (approved or pending).

 

How GEOSS works:
Data providers create standard data acess services for their data and register thouse services in an community catalogue using ISO 19115 metadata. The catalogues have been registered in GEOSS CSR (Component and service registry). The Clearinghouse then queries the registry and harvest the community catalogues.Users application then queries the GEOSS Clearinghouse which constantly quering the distributed provider catalogues.
