We all have an interest in the management of the environment since it affects all of us and our natural resources. At the same time, by our actions, we all also have an impact on the environment. Uncontrolled population growth and the rapid pace of agricultural, urban, and industrial development in developing countries, especially in Pakistan, are placing an increasing pressure on the local environment and in some cases to regional and global. In order to manage and mitigate the human impact on the environment there is an essential need of tools and method of analysis, which can help us in collating, analyzing, modeling and monitoring environmental data in a specific and sustainable manner. Geographic Information System (GIS) is one of such tool.
Geographic Information System (GIS) is computer -Based IS (using spatial references), designed to serve as a Management Tool for all phases of geographic data and its manipulation: Data acquisition, coding, storage, retrieval, analysis and display of geo-information. GIS is an effective data storage and retrieval system, having ability of portraying results on a map. Visualization is worth a “thousands words”. Since Environmental planners/Managers depend extensively upon maps for presentation and analysis. GIS can be very useful for carrying out studies and more effectively and with greater precision.
