Ecotourism can be defined as nature-based tourism that involves environmental education, interpretation of the natural environment and ecologically-sustainable management of the environmental resource (Preece et al., 1996). An environmental information system aimed at satisfying the needs of both ecotourists and environmental managers must provide spatial and non-spatial information in an accessible manner. In an attempt to provide this, a hypertext/hypermedia markup language using a World Wide Web browser as the interface has been integrated with a geographical information system to provide spatial resource information together with text, audio and graphic information. Flexibility in the system design enables the targeted user groups to select information of interest to them. This descriptive case study shows how changes in technologies delivering spatial and aspatial data enable multiple concurrent views of a data set by a geographically disparate set of domain-specific users.
