Example text

Hypermedia technology offers a set of concepts and tools that are applicable to this new era of distributed GI Services. Each node in the architecture above is a repository of GI elements. Each GI element may be either a data/information set or an analytical/processing module. These elements are encoded in various formats and media, and are interlinked with other elements that reside in the same or other network nodes. Hence, they all together compose a hypermedia system. Provided that they focus on GI, this is a Geographic Hypermedia System (GHS).

In an ideal situation, OHS constitute a central paradigm for structuring and navigating among pieces of information. This would be accomplished if all operating systems support six types of services (Grønbæk and Wiil 1997; Fig. 6): integration, interoperability, structuring, navigation, distribution and collaboration. Geographic Hypermedia Systems have special requirements including that these services must be able to handle geographic content. 3). 1 Geographic Content: Data and Services GHS handle geographic content, which consists of: (a) geographic data/information, and (b) geographic services.

Examples of typical navigation services are link traversal, querying, graphical overviews, guided tours, fish-eye views, paths, etc. A geographic hypermedia system must provide advanced navigation services, where the location and distribution of geographic objects will be highlighted. Geovisualization techniques (Kraak and Dreil 1997) must be adopted and extended for an enhanced understanding of the distribution and behavior of spatio-temporal phenomena. Distribution The pieces of hypermedia content interlinked by an OHS may be running on different computing environments in local area network and across different Internet domains.
