Generation of detailed, GIS compatible, digital urban land-use / land-cover spatial data

Since no formal geo-spatial representation of each City Region Boundary (CRB) existed, other than in broad conceptual terms, the first priority was to develop a set of generic geographic spatial modelling rules that could be used to define the actual CRB areas, as well as define other areas in the future. These rules were to be developed using appropriate satellite imagery as the primary reference base against with the CRB boundaries could be determined.
