  • “Skinning the multi-dimensional Cat” How TERN and the Unlocking the LandsatArchive Project are changing the way we look at the Earth Matthew Purss1, Adam Lewis1, Leo Lymburner1, Peter Scarth2 and Rebecca Trevithick2 1 Geoscience Australia 2013 TERN Symposium of Science, Information Technology, Innovation and the Arts QLD Department 2
  • Introduction• Background• The Unlocking the Landsat Archive Project• TERN Collaboration and Fractional Cover• “Skinning the multi-dimensional cat” 2013 TERN Symposium
  • Background• Geoscience Australia has been responsible for downlinking and archiving Landsat Earth Observations since 1979.• Historical Issues: • Data Processing is Labour Intensive • Few national-scale datasets created • Data used in a “scene by scene” approach• We are “Drowning in a Sea of Data” 2013 TERN Symposium
  • The Unlocking the Landsat Archive Project• Australian Space Research Program • $3.5M Funding (April 2011 to June 2013)• Driving a fundamental shift in the way we conduct Earth Observation Science • Automated bulk data processing • National Nested Grid Specification • Pixel level time-series analysis• Leveraging from the NCI 2013 TERN Symposium
  • The Unlocking the Landsat Archive ProjectConsortium Members Lockheed Martin Australia Geoscience Australia Victorian Partnership for Advanced Computing National Computational Infrastructure – Australian National University Cooperative Research Centre for Spatial Information 2013 TERN Symposium
  • The Unlocking the Landsat Archive Project 2013 TERN Symposium
  • The Unlocking the Landsat Archive Project End UsersProgress to Date Landsat & MODIS NCI Data Delivery (wms, wcs, wfs, wps) Australian Pixel Level 1 Reflectance Fractional Quality Orthorectified Grid Cover (NBAR) Assessment Ground Stations in Online Alice Springs and Hobart Data Hypercube Storage (Time Series Analysis) Landsat Raw Data Archive (Level 0) 2013 TERN Symposium
  • The Unlocking the Landsat Archive Project 2013 TERN Symposium
  • TERN Collaboration and Fractional Cover• During 2012 GA has Collaborated closely with QDSIIA to implement the Joint Remote Sensing Research Program Fractional cover algorithm under ULA• Calibration of satellite data using ground truth datasets: • Bare soil, Green Vegetation & Non-Green Vegetation • Calculated using models linked to an intensive field sampling program (Muir et. al. [2011]) • ~1020 ground cover control points collected by Natural Resource Management Agencies across all jurisdictions – and counting… – Funded under the “Caring for our Country” initiative 2013 TERN Symposium
  • TERN Collaboration and Fractional Cover • Low Tree Cover • Med Tree Cover • High Tree Cover 2013 TERN Symposium
  • TERN Collaboration and Fractional Cover• Some Results – Sensor Independent (Landsat 5 ~ Landsat 7) – Seamless transition from scene to scene 2013 TERN Symposium
  • 2013 TERN Symposium
  • TERN Collaboration and Fractional Cover• Results cont. – The First National-Scale Fractional Cover Product produced using the new 25m resolution Australian Reflectance Grid (ARG25) data as input. – Composite mosaic 2008-2010 2013 TERN Symposium
  • 2013 TERN Symposium
  • “Skinning the multi-dimensional cat”…• Where to from here????• Advanced pixel-level multi-spectral and multi-dimensional time-series analyses of national-scale datasets at several resolutions – Underpinned by HPC and hypercube data infrastructures• To better inform Government policy on key issues including: – Water quality and coastal ecosystems; – Forest cover monitoring; – Crop forecasting; – Dynamic landcover; – Impacts of Coal Seam Gas related activities – And many more… 2013 TERN Symposium
  • Questions???? 2013 TERN Symposium
