Geographic information system (geographic information system, GIS) is a system for collecting, storing, analyzing and graphical visualization of spatial (geographic) data and related information about necessary objects. The concept of a geographic information system is also used in a narrower sense - as a tool (software product), which allows users to search, analyze and edit both a digital map of the area and additional information about objects. A geographic information system may include spatial databases (including those managed by universal DBMS), raster and vector graphics editors, and various spatial data analysis tools. They are used in cartography, geology, meteorology, land management, ecology, municipal government, transport, economics, defense, and many other areas. The scientific, technical, technological and applied aspects of the design, creation and use of geographic information systems are studied by geoinformatics.
