Abstract

The introduction of web-services as index-portals based on geo-information has changed the conditions for both content and form of geo-communication. A high number of players and interactions as well as a very high number of all kinds of information and combinations of these characterize web-services, where maps are only a part of the whole. This chapter discusses the relations between the different components of SDI and geo-communication as well as the impact thereof. Discussed is also a model for the organization of the passive components of the infrastructure; i.e. legislation, collaboration, standards, models, specifications, web-services and finally the information. Awareness of the complexity is necessary, and structure is needed to make it possible for the geo-information community to pull together in the same direction. Modern web-based geo-communication and its infrastructure looks very complex, and it will get even more complex! Therefore there is a strong need for theories and models that can describe this complex web in the SDI and geo-communication consisting of active components, passive components, users and information in order to make it possible to handle the complexity and to give the necessary framework.
