The Geographic Information Systems (GIS) have grown to such extent that one finds its usage in multitude of public and private sector departments in many countries. As the world continues to move towards urbanization, the need for effective urban planning is further increased. However, the issue is complex partly due to the infrastructure that is already in place. We often do not have liberty to modify the existing infrastructure that was built a long time ago. We can try to work around it but we will have to compromise our urban planning needs at some point, which means that we will always try to fit in the system as to suit the already intact infrastructure.
The value of land as a resource appreciates continuously. It is not possible to achieve what we used to achieve fifty years back with the help of surveying.
Urban planning and management is a complex task, which can't be completed without the use of a powerful analytical tool like GIS.
The usage of GIS in urban planning is as an analytical and modeling tool. It can be applied to a wide array of problems. This comprises addressing problems related to data base structures, simple and complex analytical models alike.
GIS is useful in monitoring of an area or conducting a feasibility study of a location for a specific purpose e.g. evaluating the suitability of a location for the construction of a bridge or dam. Feasibility study of even smaller structures like schools and hospitals is essential and can be easily conducted with the help of GIS.
Essentially GIS aids in providing information regarding the environmental suitability of a land and its level and nature of contamination.
GIS accumulates and provides different aspects of spatial information under one system. Geographical data can be easily analyzed and worked with. This help us to portray different variants of digital information in more systematic ways.
Technologists use the monitoring properties of GIS to trace changes of pattern or behavior of a land over a specified time. It helps professionals to take decisions about the development condition of an area.
Conclusively today GIS is not just a capturing and analyzing tool but a valuable decision making toolset through spatial modeling.
