11. Service Interaction (1) GGOS Global Geodetic Observing System Project of the International Association of Geodesy (IAG) New chair since IAG Scientific Assembly 2005: Markus Rothacher Currently setting up its organizational structure IVS represented in several working groups IVS to determine representative on GGOS Steering Committee

12. Service Interaction (2) INDIGO  INter-service Data Integration for Geodetic Operations  NASA funded within the Earth Science Research, Education and Applications Solutions Network (REASoN).  The successful community-based international scientific services have evolved data information systems well- suited to users’ needs.  Space geodetic systems will be integrated, upgraded and enhanced in response to user requirements, first steps towards realizing GGOS scientific objectives.  User interface and access will be streamlined and seamless with state-of- the-art web-based services (GSAC model).
