THE COMMITTEE ON EARTH OBSERVATION SATELLITES AND ITS WORKING GROUP ON INFORMATION SYSTEMS AND SERVICES

The Committee on Earth Observation Satellites (CEOS) was established in 1984, in response to a recommendation from a panel of experts on remote sensing from space, under the auspices of the Economic Summit of the Industrialised Nations Working Group on Growth, Technology, and Employment. CEOS was created with three main objectives: • To maximise satellite Earth observation (EO) benefits through mission planning and through the development and use of compatible and standardised data products, formats, services, applications, and policies. • To serve as the primary forum for international cooperation and coordination for satellite Earth observation. • To use that forum to exchange technical knowledge and policy as a means to promote compatible satellite Earth observations systems. CEOS operates on three main levels: (i) CEOS Plenary provides overall direction and reviews progress undertaken by all CEOS elements. (ii) Working Groups, of which there are currently four, manage the technical activities and report to Plenary. These are: The Working Group on Calibration and Validation (WGCV). The Working Group on Information Systems and Services (WGISS). The ad-hoc Working Group on Disaster Management Support (DMSG). The ad-hoc Working Group on Education and Training (WG-Edu). (iii) Subgroups, reporting to their respective Working Group, carry out most of the detailed technical work, making use of specific Task Teams as required. This paper concentrates on describing the activities of WGISS and its Subgroups. The overall objective of WGISS is to facilitate the implementation of information systems and services by its members and other data providers and users of EO data. Its scope covers the capture, archiving, description, discovery, access, processing and exchange of EO data and supporting ancillary and auxiliary data and information, with the aim of improving efficiency and enabling improved interoperability and interconnectivity of information systems and services.
