What are Geographic Information (GI) and Geographic Information Systems (GIS)?
Geographic Information (GI) is “information which can be related to a location on the Earth, particularly information on natural phenomena, cultural and human resources”. Geographic Information Systems (GIS) permit all information traditionally held on conventional paper maps to be handled and stored in digital form and enable it to be linked to all other kinds of Geographic Information. If you want more detailed information about GI/GIS, see A GIS Dictionary compiled by AGI, or Introduction to GIS by the University of York.
