The project focused on a remote sensing data acquisition strategy that will respond
to the requirements for assessment of broadacre hail damage in a timely manner
within appropriate spatial and economic limitations. Current field based hail
damage assessment practices are both time and labour intensive. Integrating
remote sensing with a GIS database provides an economically viable alternative
technique for the recording, correlation, analysis and judicious evaluation of hail
damage and information for interactive administration system.
This paper will report on the remote sensing strategies, specifically hyperspectral
simulation trials and hail damage assessment using both hyperspectral acquisitions
and remotely sensed (Landsat TM and Spot Xi) imagery. Preliminary findings have
identified a good correlation (r=-0.866) between the damage levels and defoliation
with r=0.86 for both Landsat 5 TM and Spot 4 Xi sensors.
