Question: Notes on Geographical Information system? 5 pages notes on  Geographical Information system

Answer: A geographic information system (GIS) is a system for capturing, storing, analyzing and managing data and associated attributes which are spacialy referenced to the earth. In the strictest sense, it is a computer system capable of integrating, storing, editing, analyzing, sharing, and displaying geographically-referenced information. In a more generic sense, GIS is a tool that allows users to create interactive queries (user created searches), analyze the spatial information, and edit data. Geographic information science is the science underlying the applications and systems, taught as a degree program by several universities.\n\nGeographic information system technology can be used for scientific investigations, resource management, asset management, Environmental Impact Assessment, Urban planning, cartography, and route planning. For example, a GIS might allow emergency planners to easily calculate emergency response times in the event of a natural disaster, or a GIS might be used to find wetlands that need protection from pollution.
