Are SDIs serving the needs of local planning?: case studies of Victoria, Australia and Illinois, USA

Abstract

National spatial data infrastructures (SDI) have been initiated and built throughout 1990s in both Australia and the U.S., initiated and coordinated by the Australia New Zealand Land Information Council (ANZLIC) and the Federal Geographic Data Committee (FGDC), respectively. Numerous SDI-related activities at the national, state, and local level in both countries share similar core objectives, which are to stimulate coordinated collection, dissemination, and use of spatial data by public and private entities. This coordination is to result in digital databases that would be easily accessible and seamless across administrative and organizational boundaries and that would help secure social, environmental, and economic benefits to the involved communities. The improved information resources at the local level in particular are expected to contribute to sustainable urban development and to enhance the cooperation between government and nongovernment sectors. This paper raises the question about the actual effectiveness of the existing SDI developments and about the outcomes of the related interactions between the local, state, and national levels. Case study of local governments in Victoria, Australia and Illinois, U.S. are used to evaluate the utility of existing SDIs to local planning activities and to offer recommendations for increasing their effectiveness in supporting sustainable development.
