The Working Group on Information Systems and Services
(WGISS) of the Committee for Earth Observation Satellites (CEOS) focuses on the
provision of products, tools and services to realize the full potential of
earth observation satellite data. Members of WGISS are representatives from
space agencies and major programmes (typically in the
field of global environment) affiliated to CEOS. WGISS work covers information
systems and services from the ground segment through to the provision of
complete datasets for specific applications. WGISS serves both experienced
users of Earth observation data in industry and scientific research as well as
those investigating applications of earth observation data for the first time. The
creation and standardization of metadata to support the discovery of, and
access to, data is an important aspect of this work. The co-ordination of member
Agency computer networks, making use of the Internet where appropriate, is also
a major feature of the activities.
This presentation will give an overview of the main
activities and progress of the technology and services within WGISS. It shall
cover the internal management of data, the creation of information systems and
the delivery of interoperable services.
Especial it shall give an interest example to show the full range of the
information processing chain from the initial ingestion of satellite data into
archives through to the incorporation of derived information into end-user
applications.
