The Technology and Services Subgroup (TSSG) of the CEOS Working Group on Information Systems and Services (WGISS) covers internal management of data, the creation of information systems and the delivery of interoperable services. The interests of the Subgroup span 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. The creation and standardisation of metadata to support the discovery of and access to data will be an important aspect to this work. The co-ordination of member Agency computer networks, making use of the Internet where appropriate, will also be a major feature of the activities.

The membership to the CEOS WGISS TSSG is open to all members and associates of CEOS. CEOS WGISS TSSG may invite guest participation from other organisations by decision of the sub-group members.

The Technology and Services Subgroup is on of two subgroups under CEOS WGISS as depicted below.
