Geographical Information System
GIS allows us to browse, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts. A GIS system helps answer questions and solve problems by looking at your data in a way that is quickly understood and easily shared. With the help of powerful technical tool now we have the potential to organize complex spatial environment with tabular relationships. The emphasis is on developing digital spatial database, using the data sets derived from precise navigation and imaging satellites, aircrafts, digitization of maps and transactional databases. The power and potential of GIS is limited only by ones imagination. In simplified terminology, the term describes any information system that integrates, stores, modifies, analyzes, shares, and displays geographic information. In a more generic sense, GIS applications are tools that allow users to create interactive queries (user created searches), analyze spatial information, edit data, maps, and present the results of all these operations. Geographic Information System is the system which concatenates the geographic concepts, applications and with the technological Systems. GIS data represents real world objects (roads, land use, elevation) with digital data. The condition of the Earth's surface, atmosphere, and subsurface can be examined by feeding satellite data into a GIS. GIS technology gives researchers the ability to examine the variations in Earth processes over days, months, and years. For example, the changes in vegetation vigor through a growing season can be animated to determine when drought was most extensive in a particular region. The resulting graphic, known as a normalized vegetation index, represents a rough measure of plant health. Working with two variables over time would then allow researchers to detect regional differences in the lag between a decline in rainfall and its effects on vegetation. Many disciplines can be profited from GIS technology. Wider use of the technology can be found throughout science, government, business, and industry, with applications including real estate, public health, crime mapping, national defense, sustainable development, natural resources, landscape architecture, archaeology, regional and community planning, transportation and logistics. GIS is also diverging into location-based services (LBS). LBS allows GPS enabled mobile devices to display their location relative to fixed assets (nearest restaurant, gas station, fire hydrant), mobile assets (friends, children, police car) or to relay their position back to a central server for display or other processing. These services continue to develop with the increased integration of GPS functionality with increasingly powerful mobile electronics (cell phones, PDAs, laptops).GIS could be a valuable tool not only for mapping facilities but for improved decision-making, better asset infrastructure and identifying source of Transmission and Distribution losses.

In the era of technological paradigm, Geographic Information System (GIS) is a system which integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information.
