Take a look around you… notice how every feature has its own unique and precise location. These locations can be fixed by geographical coordinates and measured in one, two or three dimensions in space. The process of linking features with geo-referenced coordinates creates spatial data, and these data are stored and managed in geographic information systems (GIS). GIS have revolutionized the way that spatial data are used – many aspects of our everyday lives are connected with GIS in one way or another, from the obvious Google Earth and mobile location technologies to morning mail delivery, our electricity supply, through to weather forecasts every evening.
