Are SDIs serving the needs of local planning? Case study of Victoria, Australia and Illinois, USA

Abstract

National spatial data infrastructures (SDI) have been built throughout the 1990s in both Australia and the USA, conceptualized and initialized 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 levels in both countries share similar core objectives 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 contribute social, environmental, and economic benefits to the involved communities. Improved information resources, at the local level in particular, are expected to aid decision-making process and to enhance cooperation between government and non-government sectors. This paper raises a question about the effectiveness of existing SDI developments and about outcomes of the related interactions between the local, state, and national levels. Case studies of local governments in Victoria, Australia and Illinois, USA are used to evaluate the utility of existing SDIs to local planning activities and to make suggestions for increasing their effectiveness.
