The GIS literature abounds with strategies to guide the development of a corporate GIS as a single project but lacks discussion on the long term management of the GIS. This paper documents a recent study into GIS development in a state department over an 18-year period. It applies the productional perspective of GIS to model long term GIS development diagrammatically and identi es ve patterns of GIS development. The outcomes reveal some long term characteristics of a corporate GIS, based on which a three-stage approach is developed to guide the long term development of an ideal corporate GIS.
