Therefore, GIS links spatial data with geographical information about a particular feature on the map (See: volusia.org).

ii) GPS (Global Positioning System) GPS is a satellite based positioning system operated by USA. It consists of satellites. It is a data collection tool for GIS. Basically, the signals from the satellites in GPS are received by GPS receivers on the earth. Therefore, different stations are earmarked on the earth covering a particular area. It is the matching of the satellite with the receiver which plays an important role. Certain discrepancies in the matching are got over by differential GPS (See: esri.com).
