Bottom Line: WebView, the Internet extension to ArcView, publishes HealthCyberMap ArcView Views as Web client-side imagemaps.This paper describes HealthCyberMap simple, low-cost method for "patching" WebView to serve hypermaps with dynamic database drill-down functionality on the Web.CONCLUSION: The authors believe their map serving approach as adopted in HealthCyberMap has been very successful, especially in cases when only map attribute data change without a corresponding effect on map appearance.

ABSTRACT
BACKGROUND: HealthCyberMap http://healthcybermap.semanticweb.org aims at mapping parts of health information cyberspace in novel ways to deliver a semantically superior user experience. This is achieved through "intelligent" categorisation and interactive hypermedia visualisation of health resources using metadata, clinical codes and GIS. HealthCyberMap is an ArcView 3.1 project. WebView, the Internet extension to ArcView, publishes HealthCyberMap ArcView Views as Web client-side imagemaps. The basic WebView set-up does not support any GIS database connection, and published Web maps become disconnected from the original project. A dedicated Internet map server would be the best way to serve HealthCyberMap database-driven interactive Web maps, but is an expensive and complex solution to acquire, run and maintain. This paper describes HealthCyberMap simple, low-cost method for "patching" WebView to serve hypermaps with dynamic database drill-down functionality on the Web. RESULTS: The proposed solution is currently used for publishing HealthCyberMap GIS-generated navigational information maps on the Web while maintaining their links with the underlying resource metadata base. CONCLUSION: The authors believe their map serving approach as adopted in HealthCyberMap has been very successful, especially in cases when only map attribute data change without a corresponding effect on map appearance. It should be also possible to use the same solution to publish other interactive GIS-driven maps on the Web, e.g., maps of real world health problems.

Also note the overview map with a red positional square on the right; this helps users know where they are within the larger world map which cannot be displayed in full detail in one screen. The overview map is also clickable and can be used to select a different area for viewing. The world map is rendered as a chorochromatic map. Health information resources are mapped to countries (of authors/publishers) rather than cities and listed in a separate pop-up text window (query result page) to avoid map clutter. The latter would have been unavoidable had we opted to represent each resource using a distinct point symbol on the map ( cf. Map.Net – . Note the "Find resources having the same primary subject as this one from all over the world" link at the end of each resource bibliographic card in the resource list pop-up window to the right.

Mentions: HealthCyberMap (HCM – ) is a Web-based service that aims at mapping parts of medical/health information resources in cyberspace in novel semantic ways to improve their retrieval and navigation. This is achieved through intelligent categorisation and interactive hypermedia visualisation of the medical/health information cyberspace using metadata (information about information resources), clinical codes (to describe resource topics) and GIS (Geographic Information Systems) technologies. HCM pilot currently provides six different interfaces to its metadata base, which has over 1600 resource records in it. Some of these interfaces are visual (maps – Figure 1), while others are textual (list of topical categories and a semantic subject search engine).
