Developing Web Geographic Information System with the NDT Methodology

چکیده
The increasing popularity of the Internet has led to the development of Web applications, known as Web GIS. A geographic information system (called GIS from now) is a software system that manages geo-referenced information. GIS systems are an automated system used for storing, analysing and manipulating geographical information. Geographical information represents objects and actions where geographical location is indispensable information (Aronof, 1989; Bull, 1994). In this context, a Web GIS system offers different GIS services for analysis and visualization of geographical information on the Web (Kim, 2002).
