Principles of hypermaps

In this paper we describe the functionality of a hypermap. Hypermaps are defined as georeferenced multimedia systems that can structure individual multimedia components with respect to each other and to the map. They will let users navigate multimedia data sets not only by theme but also spatially. The concept discussed here is supplemented by a prototype developed in an authorware environment, using IconAuthor software. The prototype functions are accessible through the World Wide Web (http://www.itc.nl/ similar to kraak/hypermap/delfthypermap.html). (C) 1997 Elsevier Science Ltd.
