Description :
In order to calculate the indices, different sources data are selected, including land use maps, former land use planning, land price and floor-area-ratio samples, digitized map of the highways and city centers, population and GDP statistical data, etc. Various GIS spatial analysis methods are used to spatialize these indices into 100m x 100m cells. Besides, an integrated urban sprawl index is calculated by weight sum of these 13 indices. Four sprawling patterns are identified : randomly expansion at urban fringe, strip development along or between highways, scattered development of industrial land, leapfrog development of urban residence and industrial area.
