Abstract
Geographic Information Science or what is so called GIScience is an applied science, which involves spatial or geo data collection and analysis. It consists of three major fields: remote sensing, GIS and GPS. GIS is one of the most important techniques used to analyze spatial data. Internet-based GIS in some ways resembles the classic "mainframe and terminal" computer hardware model. That is, one computer does the actual GIS processing and the other is connected to it through a network—in this case, the Internet—and acts as the display terminal for the maps, images, and data tables which are produced by the GIS. The above-mentioned approach is known as "server-side" processing since a server will produce the results and send them back to the user's Web browser, also known as the "client".
