2、es of land use planning that explore a very wide range of aspects of the built and social environments of urbanized municipalities and communities. GIS is currently used by urban planners, engineers and surveyors to research, develop, implement and monitor their plans as they become carried out. The
3、re are many databases containing maps often created by USGS. Each municipality or organization has access to these databases and can add information which could include age structure data, population density, zoning, tax assessment, etc. The Internet and the World Wide Web have been hailed in the po
4、pular press as revolutionary medium of communication for the next millennium. The Web is opening up new forms of computer-mediated communications, allowing for new forms of information dissemination, social interaction and collaborative working. This is particularly so for the planning community wit
5、h the intense drive to develop GIS further in terms of widening and deepening access to spatial information along with appropriate analytical functionality within the network paradigm of the Web and the browser interface.

Targeted Audience: This serves to be useful for planners, general public and engineers who are involved in infrastructure development.Pros: The positive features of this website are in addition to the common tools li
8、ke zoom in, zoom out, it also has some useful tools like identify, tooltip, measure and add point of interest. All these features enable interactive mapping. Also, it has a overview window at the right-bottom corner which helps us locate our position in the whole area. It also provides the XY locati
9、on of the area as the cursor moves through the map. Cons and Improvement: The drawbacks of this site are that certain information like addresses, parcels, soils and orthophotographs are not available for the public to access. Though they are present, they are disabled. These need to be rectified to
10、make the application better.Internet GIS Software: The Internet GIS software used in this website is Mapserver. MapServer is an open source development environment for building spatially-enabled internet applications. It can run as a CGI program or via Mapscript which supports several programming la
11、nguages. MapServer is not a full-featured GIS system, nor does it aspire to be. Instead, MapServer excels at rendering spatial data (maps, images, and vector data) for the web. Beyond browsing GIS data, MapServer allows us to create geographic image maps, that is, maps that can direct users to conte

16、d Revenue There is a detailed legend given for each map. When clicked on the info tool and click on a map feature, it gives almost all possible information on it.Cons and Improvement: Interactive mapping component is missing in this application. That is the user is not able to add a point of interes
17、t or measure anything. This site can be improved by adding these features.Internet GIS software:The Internet GIS software used to develop this application is Caliper Maptitude. Maptitude for the WebTM has all of the tools we need to create compelling and attractive maps, plus special capabilities fo
18、r designing and running interactive web mapping applications and GIS web services on the World Wide Web. we can quickly create simple applications, without programming, by using an existing template and linking it to our geographic data. Experienced programmers can create complex web applications an
19、d web services by accessing a rich set of .NET classes and modifying the source code for the existing templates.c) http:/www.uthungulu.org.za/udmgis/mappage.aspx(Level B2)Purpose: uThungulu is one of the 11 district municipalities (districts) of KwaZulu-Natal province in South Africa. This web mappi
20、ng application disseminates a variety of information such as towns, local municipalities, water pipelines, projects, census 2001, roads, etc. Uthungulu is an area requires urban development and this website lays the foundation upon which the projects can be built upon.Targeted Audience: This website
