Introduction to WGISS For GEO ADC Martha E. Maiden CEOS WGISS-26/GEO ADC Boulder, Colorado September 22, 2008

WGISS Mission and Objectives Mission Statement Recognizing the importance of global users, the WGISS will stimulate, coordinate and monitor initiatives, thereby enabling users at a global, regional and local level to exploit more effectively, and benefit from, data generated by Earth observing satellites and other sources. Objectives The overall objective of WGISS is to facilitate data and information management and services for users and data providers in dealing with global, regional and local issues. It will address in particular the description, access, retrieval, archiving, long-term preservation, utilization, and maintenance of spaceborne Earth observation data and supporting ancillary and auxiliary data and information, enabling improved operability and interconnectivity of information systems and services.

WGISS Specific Objectives Enable Earth observation data and information best practices and services to be more accessible and usable to data providers and data users world-wide through international coordination; Enhance the complementarity, interoperability and standardization of Earth observation data and information management and services with other types of geospatial data such as in-situ data; Foster easier exchange of Earth observation and related data and information to meet the requirements of users and data providers; and Foster the development of information best practices and services that use spaceborne Earth observation data.

About WGISS WGISS agencies have a vast quantity of data, systems, and other resources that can support science or applications WGISS is working to make these resources accessible through a common set of discovery, search, access, and service interfaces. WGISS works closely with standards organizations like OGC (Open Geospatial Consortium) and ISO (International Standards Organization) to ensure that the CEOS WGISS data and tools can interoperate with the different national and international spatial data infrastructures and to facilitate the development of commercial products that implement the common interfaces. WGISS has large roles in several GEO Tasks and is a key participant in the GEO Architecture and Data Committee

WGISS Current Focus Provide satellite arm of GEO System of Systems Innovative contributions that will persist, and can be reused Work closely with and support CEOS Virtual Constellations (GEO DA-07-03) High GEO interest in LSI Portal Work closely with collaborate with CEOS Working Group on Calibration and Validation Support the CEOS Plenary Chair’s Data Democracy initiative.

WGISS and Science Communities A science community may need only a small part of the WGISS products and services Data Services Science Community Views WGISS works with science communities to tailor its offerings for the science or application. A small part of the total WGISS resources may be needed by a science community. Now we will look at a few examples of this. WGISS Products & Services
