Geographic Information Systems are conventionally defined as systems that capture, store, manipulate and output geographical information. Geographical information may be considered as information that is tied into some specific set of locations on the earth's surface, including those immediately adjacent: the sub-surface, oceans and atmosphere. 'Spatial' is now starting to become a commonly used term or synonym for 'geographical'. The term 'geospatial' is gaining currency and also describes the trend towards convergence of spatial technologies such as Global Positioning Systems (GPS), aerial and remote sensing and context-aware computing.
GIS emerged from three principal roots: the need for data analysis and display tools, the automation of map production, and landscape architecture and environmentally sensitive planning. Although GIS have been available since the 1960s, it is only in recent years that hardware and software have become sufficiently powerful and inexpensive for its use to become widespread.
