Geographic Information System (GIS)
A geographic information system (GIS) is a conceptualized framework that provides the ability to capture and analyse spatial and geographic data. GIS applications (or GIS apps) are computer-based tools that allow the user to create interactive queries (user-created searches), store and edit spatial and non-spatial data, analyze spatial information output, and visually share the results of these operations by presenting them as maps.
Geographic information science (or, GIScience)—the scientific study of geographic concepts, applications, and systems—is commonly initialized as GIS, as well.
Geographic information systems are utilized in multiple technologies, processes, techniques and methods. They are attached to various operations and numerous applications, that relate to: engineering, planning, management, transport/logistics, insurance, telecommunications, and business. For this reason, GIS and location intelligence applications are at the foundation of location-enabled services, that rely on geographic analysis and visualization.
GIS provides the capability to relate previously unrelated information, through the use of location as the "key index variable". Locations and extents that are found in the Earth's spacetime, are able to be recorded through the date and time of occurrence, along with x, y, and z coordinates; representing, longitude (x), latitude (y), and elevation (z). All Earth-based, spatial–temporal, location and extent references, should be relatable to one another, and ultimately, to a "real" physical location or extent. This key characteristic of GIS, has begun to open new avenues of scientific inquiry and studies.
Warwick (/ˈwɒrɪk/ WOR-ik) is a market town and county town of Warwickshire, England. It lies near the River Avon, 11 miles (18 km) south of Coventry and west of Leamington Spa and Whitnash. Its population was 31,345 in 2011. Signs of Neolithic activity precede unbroken habitation to the 6th century AD. It was a Saxon burh in the 9th century; Warwick Castle was built during the Norman conquest of England. Warwick School claims to be the country's oldest boys' school. The earldom of Warwick, created in 1088, controlled the town and built its walls, of which Eastgate and Westgate survive. The castle became a fortress, then a mansion. The Great Fire of Warwick in 1694 destroyed much of the town. Warwick missed industrialisation, but the population has grown almost sixfold since 1801.
