AusCover Remote sensing for Australian environments Dr Bek Christensen
www.auscover.org.au
AusCover Produc1on and delivery of na#onally consistent long-‐1me series of satellite-‐based biophysical map products and next genera1on remote sensing research data that is validated for Australian condi#ons.
Remote Sensing Data Delivery Backbone • Solving data formats, interoperability, data-‐policy, • Physical storage, efficient delivery to end-‐users etc.
Data Produc;on Network • Na1onally-‐consistent, standard biophysical data products, • Metadata and technical support documents • Specialised space-‐borne, airborne & in-‐situ research-‐grade data
Ground Valida;on Program and Instrumenta;on • Set na1onal standards & field valida1on protocols • AusPlots, SuperSites and Environmental transects etc. • Interna1onal Benchmarking

Infrastructure
• Data products – satellite, airborne, field • Data delivery and access • Tools and protocols • Networks and exper1se
Landcover dynamics and phenology
• Frac1onal cover • Persistent green • Phenology
Vegeta1on Structure • Biomass – library published, map coming soon • Height • fPAR, LAI
Biomass field data
Fire dynamics and impacts
• Burned area • Grassland curing • Hotspots
Burnt area map – different colours represent different dates of burning
Cal/val
• Star transects + tree structure • Terrestrial LiDAR (TLS) • Hemispherical photos • Airborne hyperspectral and LiDAR Hemi photo, Chowilla
TLS scan, Tumbarumba
Other environmental data
• Water vapour • Cloud • Surface reflectance • Rainfall • Air temperature • Water vapour pressure • Solar radia1on • Land surface temperature
Daily solar radia1on
Daily rainfall

Networks and exper1se
In development (2016-‐2017) • UAV (mul1spectral, hyperspectral, thermal,
LiDAR) • New data streams, e.g. Himawari-‐8, RADAR,
Sen1nel1&2 • Improved user-‐friendliness – online tools to
visualise and explore data products
16/17 and beyond • Reinvigora1ng na1onal network • Improving useability for non-‐research
audience • Engaging user community now to understand
needs for the future…
