Navigating Through Earth-Observation Knowledge

M. Zingler & R. de Marcantonio

Earth observation (EO) from space is a highly specialised technological domain where data and terminology need to be presented to users in an understandable language and customised to meet particular requirements. Most applications that use remote-sensing data require a high level of user expertise – the selection of EO products and their potential for specific applications is not always obvious. In addition, different EO user communities have varying requirements with respect to data, sources and other information when they access EO user services.

To ensure that the required information is obtained efficiently, yet with maximal flexibility, the interface between ESA’s EO user services and the wide spectrum of users will have to incorporate some aspects of a knowledge-based system. Intelligence in user systems will be required for occasional users or where help concerning complex subjects is required for a time-efficient and successful session.
