SDI development - why aren’t we there yet ?

Australian governments • three levels of government • legal separation • some functional overlap • environmental data (yes) • cadastral data (no) • scale and scope of applications
Australian SDI coordination • Australia New Zealand Land Information Council (ANZLIC) • Commonwealth Spatial Data Committee (CSDC) • Intergovernmental Committee on Surveying and Mapping (ICSM) • Public Sector Mapping Agencies (PSMA)
Australian SDI programs • institutional framework • policies, principles, compliance • fundamental data • specify, create, maintain • technical standards • metadata, data quality, dictionary • clearinghouse • metadata, directory, access
So why don’t we have a fully functional SDI (anywhere) ? • www site • define area of interest • view all metadata • download selected data • integrate own data • apply web mapping tools
Key elements • data • technology • business case
Data • drowning in it ! • raster (image) and vector (map) • accessibility ? • quality ? • accuracy • currency • consistency • completeness
Technology • It’s brilliant ! • internet • communications • storage • data standards • applications
Business case • government policy imperative • patch protection- governments, agencies, individuals • revenue implications • killer application • commercial imperative • role of the private sector • return on investment
Conclusion • many governments are investing heavily in SDI development • Australian approach matches our political structure • SDI development is constrained by the lack of an overpowering business case
