Geographic Information Systems (GIS) 6
Geographic Information Systems (GIS) 6 : An organized collection of tools (computer hardware and software), of information and of professional/technical knowledge which is used to input, store, retrieve, utilize, analyse and output geographically referenced data. A GIS uses geography as its organizing principle. A GIS is particularly useful in situations with a spatial dimension, such as knowing the locations of refugees, where water taps are and how far refugees need to walk to school.
