Abstract
Internet-based GIS (WebGIS) development on infectious disease is a challenge, especially during its severe outbreak. Global SARS information WebGIS we developed is a typical case application. This work discusses the methods and steps on how to design and develop the WebGIS application. A "thin-server" and Java Applet based WebGIS solution is employed to address the Internet access problem with high-visits. A data collection and management system is developed to process SARS data and provide updated data files that the WebGIS application needs. System framework design and client-side functionalities development are presented in detail.
