4. AusCover field and airborne campaigns
Field-based Measurements Airborne Measurements Satellite Based Measurements
Time-Series Measurements
11. Robson Creek campaign and site
• 9-16 September 2012
• 18pin the field
• Dense mesophyll vine forest
• Highest biomass in Australia
• Critical to constrain and validate remotely sensed models
13. Field and airborne data collection design
• Each site represents dominant
biome
• Homogenous 5 x 5 km sites
• Capture variability within site
• Field data collection influenced
by accessibility and type of
environment
TLS Flux tower
FPC / Structure
Hemi & LAI-2200 or TLS
14. Field and airborne data collection design
• Homogenous plots
• Ground, mid-storey and
over-storey
• Basal area
• Vegetation structure
• LAI (LAI-2200)
• Hemispherical photos
• Terrestrial Laser Scanning
• Leaf samples and species
ID
• Phenology photos
34. Collaboration and sharing of data
• Data collection suitable for multiple TERN facilities, e.g.
ASN, OzFlux, AusCover
• Other collaborations: CSIRO, JCU and UQ researchers and
QLD Government (DSITIA)
• 25Ha plot: Species, DBH, tree height
• Species mapping: hyper-spectral data, species ID, leaf
samples, spectrometer measurements
• Link flux measurements, productivity estimates, 25Ha
plot, LiDAR/Hyper-spectral data, AusCover biophysical
parameter time-series, phenology assessment
• Vegetation mapping, condition and change: WTMA, QPWS
• Biomass estimates: TLS, LiDAR, structural measurements
