Geographic Information Systems for the sugar industry

GIS is less than 20 years old but is emerging as one of the fastest growing application areas for interactive computer graphics. Once limited to users who could afford expensive systems requiring expert staff, GIS is experiencing a surge of acceptance. This is due to advances in software technology, powerful and inexpensive workstation networks, and growing user interest. New and experienced users, at all levels of industry, research and government, are discovering that GIS can work for them. GIS has made it possible to condense tasks that once took months to a matter of minutes. There are essentially two types of basic data contained in GIS: spatial and non-spatial. Spatial data represent objects that have physical dimensions.
