  1. Development of the Australian Hydrological Geospatial Fabric (Geofabric) Spatially enabling the Australian government’s national water information program

  2. Growing Urban Demand Over-allocation to Irrigation Drying & Warming Climate The big 8 water scarcity factors Expanding Plantations Uncapped Groundwater Extraction Bushfire Recovery Impacts Expanding Farm Dams The Environmental Flows Imperative Water scarcity: A deepening problem.

  3. Recent inflows into the Murray system.

  4. Inflow forecasts for the Murray system.

  5. Judicious infrastructure investments Accurate and timely flood warnings Properly functioning water markets Good water information is the key Prudent environmental flow management Greater efficiency in water use Fair pricing and equitable sharing of a scarce resource Information to support water reform.

  6. The Bureau’s new water information role. • 10-year Commonwealth program, started July 07 • $450m funding • 110 new staff (added to 40 existing) • Based in all States, concentrated in VIC and ACT • New IT infrastructure • Legislative backing • Water Act 2007 • Water Regulations 2008

  7. Our activities. • Set standards for water data measurement and transmission. • Collect primary information from water data holders and build a national repository. • Provide a range of value-added water information products and services for the nation. • Assist water data holding agencies to modernise their observing systems. • Invest in water information R&D and opereationalise the outputs.

  8. Our water information product suite.

  9. Provider data Information products AWRIS Streamflow Dynamic Diversions REPORTING SERVICES Climate DB Groundwater Browser, RSS, XML FORECASTING SERVICES Water quality Storage Water Data Geofabric Static Water use NATIONAL WATER ACCOUNT Entitlements and Trades Rolling annual reports NATIONAL WATER RESOURCE ASSESSMENT Hydro DB Various spatial data layers

  10. The Australian Hydrological Geospatial Fabric (aka ‘the geofabric’) The AHGF will be a suite of authoritative spatial data products containing a consistent representation of every feature, and the connectivity between features, of the Australian water system. The AHGF will become the framework geospatial information upon which Australia’s water information related activities are based and through which they are related.

  11. The Geofabric • Being built for BoM initially, but will have value for others eventually • Managed by BoM - GA, CSIRO, ANU, States assisting • Phase 1 due end 2009 • R&D underway for the future (WIRADA) • Envisage cross-government collaboration and governance

  12. Key signposts for Geofabric implementation. • Implementations • NHD/NHD+ • CCM2 • Canadian Groundwater Model • LYNX data management • Tools • ArcHydro • LYNX/Radius topology • Models and Data Product Specification Methodologies • Hydro ad-hoc • INSPIRE will adopt a DPS for each theme • ANZLIC Harmonised Data Model

  13. Geofabric Development Plan • A road map for delivering foundation data products • National Surface Hydrology Dataset • National DEM • National Reporting Units • Investment Plan for Regional Scale Data

  14. Surface Hydrology“AusHydro” Development Path Developing a single point of truth hydrography layer for Australia Topologically structured to allow network analysis and integration with the hydrometric gauging network. Will contain both natural and man-made features V1.0 is a reconciliation of existing national data V2.x will involve incorporation of larger scale data on a catchment by catchment basis The Development Plan is limited to scoping V2 of AusHydro based on a comprehensive data audit and assessment Aiming to optimise investment and mitigate risk

  15. Surface Hydrology“AusHydro1.0” - Reconciling the national datasets

  16. Surface Hydrology“AusHydro2.0” Scoping integration of regional data Currently no nationally consistent hydrography at a scale larger than 1:250,000 Cartographic not hydrologic National data compiled at 1:100K State data a mix of 1:25K-1:100K A comprehensive data quality assessment is being undertaken to focus investment and minimise risk

  17. Surface Hydrology“AusHydro2.0” Data Quality Assessment Nature and quality of regional scale data varies We are not currently in a position to propose a fully costed plan for incorporating regional scale data. Comprehensive assessment of: Completeness Spatial Accuracy Logical Consistency Red = regional data, Orange = 1:250K

  18. Systematic sampling of the entire continent Assess the quality or data against best available imagery Produce catchment-by-catchment “quality maps” Undertake production pilot to cost the clean-up Basis for making investment decisions on catchment-by-catchment investment decisions Will provide the basis for seeking co-investment Surface Hydrology“AusHydro2.0” Data Quality Assessment

  19. National Reporting Units First formal revision since AWRC (1976). V1.0 based on the 9” DEM and 1:250k ‘blue lines’. V2.xx based on SRTM 1” DEM and evolve as other DEM and blue-lines improve Nationally consistent and physically based. Linked to hydrometric gauging network Reconciled with the AWRC Basins Will deliver a nested catchment database for Australia.

  20. National Reporting Units- Topographically defined drainage basins • All of the catchment area that drains to a river mouth or terminal sink • 25,000 true depressions • 54% by area inland drainage

  21. National Reporting Units- Proposed Hierarchical Catchment Framework

  22. Digital Elevation Model- SRTM Development Path SRTM DTED2 (1sec) will open up the interior of Australia There is information on landscape structure never seen before SRTM DTED2 has proven to be more suited to automatic artefact and vegetation removal. Major investment will still be required in manual editing and data integration All other options are very expensive Likely to be made obsolete by new data sources within 5 years Available for whole of government use (Fed, State. Local, NRM bodies) CSIRO undertaking the work as part of WIRADA with GA and ANU assistance STRM DTED2 (1sec) offers the most consistent and cost-effective platform for the next National DEM 9sec DEM 1sec SRTM DEM

  23. Digital Elevation Model- SRTM Development Path 9 second SRTM 1 second

  24. SRTM - DSM with systematic and sensor errors resolved. SRTM - DEM with vegetation removed through automated processing. SRTM – DEM-H250 – V2 with 1:250K drainage enforcement. MDBC by mid-2009 SRTM – DEM-H250B – V3 with all vegetation areas where V2 failed, either manually edited, removed or merged with agreed alternative (eg new VICDEM). SRTM – DEM-HB – V4 with best available drainage enforcement. X…n. On-going integration with best-available data (eg lidar). Digital Elevation Model- SRTM Development Path National Elevation Data Framework (NEDF)

  25. Digital Elevation Model- SRTM Development Path Noise removal Veg’ removal Adaptive smoothing & Drainage enforcement

  26. SRTM 1 contribution to catchment delineation
