An Overview On Gis, Its History, Working And Its Application In Various Fields Deepali And Namita Joshi Department of Environmental Sciences, Kanya Gurukul Campus, Gurukul Kangri University, Haridwar, Uttarakhand, India. Abstract:Environmental deterioration has taken place along with excessive extraction of ground water as a result of industrialization and urbanization. Pollution load due to industrial effluents is also a matter of serious concern not only for the quality of nearby aquatic body but also for living being residing there. It seeps into the aquifers and pollute the ground water, which has adverse effects on users health. Hence industrialization offers a wide scope of ground water contamination and depletion of ground water level through excess extraction. GIS has been found very useful in establishing the spatial relationship between pollution level and its source. Now it is a readily available spatial analysis tool which gives unique and unparalleled insights into the natural and manmade environments due to its strength to link the "generic information" with its "location". It not only analyses the present environmental scenario but also helps in projecting the future, in other words, one can effectively use the GIS tool for past, present and future studies on environment and its protection for the generations to come in future GIS can be effectively used in environmental management and planning, ground water quality analysis and mapping, fresh water and saltwater interface, solid waste and waste water management, air & water pollution, natural hazards and their mitigation etc. This paper primarily focuses on the brief history, benefits and utilities of GIS in different field of environmental sciences. isrj.net/UploadedData/3029.pdf
