Geographic Information System as Knowledge & Technology Integration

This paper exhibits the process of Geographic Information Systems (GIS) ability to separate great quantities of information about the environment into layers, explore each layer with a powerful suite of analytical tools, and then combine the layered information to use it in an integrated fashion which makes the GIS a powerful and effective decision-support tool. This tool generally used for any computer based capability for manipulating and organizing geographic data with different techniques. With the extent of this, this paper deals with some GIS applications and Informative examples which furnish better understanding of GIS integrative techniques with respect to relational data which can be used for different purpose appliances. Especially rapid developments in remote sensing, Science and technology play a major role in the growth of GIS, through this gathering of spatial information by means of proper management about earth and its environment into vast storehouse is a very important process for any GIS application.
