Abstract
HyperText Markup Language (HTML) is a platform-independent method of identifying a document's structure and references. Web is a distributed hypertext multimedia information service that brought millions of non-academic and academic users to net. While in contrast to traditional GIS, multimedia Web GIS is not only able to collect, analyze and store the data in traditional formats i.e. text, images (pictures) and graphs but also audio (sound), animations and video (moving pictures) as well, using all the techniques, advantages and multimedia facilities of Web. In this paper, the multimedia data along-with the advantages of multimedia GIS (MMGIS) over traditional GIS are explained. HTML plays a robust role in the development of the multimedia Web GIS. Through HTML our multimedia Web GIS can be viewed into three different categories. These are Static Web GIS, Dynamic Web GIS, and Active Web GIS. These three broad categories are also discussed briefly in this paper.
