Rationale for National Map
• Initiative of Office of Spatial Policy (Dept of Comms) to:– Provide easy access to authoritative and other spatial data
to government, business and public– Facilitate the opening of data by federal, state and local
government bodies– Provide an open framework of geospatial data services that
supports commercial and community innovation
More users using data services
More data services available

10 design goals for an open national map1. Authoritative data services
– Eg Administrative boundaries, place names2. Multi-jurisdiction
– Live data services for commonwealth, states, local government3. Multi-custodian
– Live data services from different agencies - GA, ABS, BoM, state agencies4. Multi-vendor (at back end)
– ESRI’s ArcGIS, Google Maps Engine, open source software (eg Geoserver)5. Multi-format
– OGC-compliant data services, KML, GeoJSON, CSV, etc6. Open framework
– All data sets and services available for other compatible front-ends7. Open source
– Open source front-end; back-end data services can use open source8. Easy access to the data set/service itself from the National Map UI
– Map provides visualisation but all data can be directly accessed too9. Features not available in current globes
– Timeline, water flow direction, subsurface, etc10. Platform for commercial and community innovation
– Interfaces to support value-add services (eg analytics, visualisation, sharing, printing)

Current available data services• All now available from their custodian and in National Map• Land (Geoscience Australia)
– Gravity, land cover, magnetic image, surface geology, hillshade • Water (Bureau of Meteorology’s Geofabric)
– Water bodies, streams and rivers, catchments, estuaries, boreholes, waterholes, river regions, drainage divisions, aquifer contours, water table aquifers
• Infrastructure (Geoscience Australia’s Geotopo 250k)– Roads, railroads, airports, ferry routes, pipelines, power lines
• Boundaries (Australian Bureau of Statistics)– States and territories, local government areas, postal areas, commonwealth
electoral divisions, state electoral divisions, state suburbs, natural resource management regions, Australian drainage divisions, tourism regions, statistical boundaries
• Population (Geoscience Australia)– Cities– Populated places
• Other data sets and services at data.gov.au• Lots more coming!
