INTEGRATION OF HYPERSPECTRAL AND POLARIMETRIC RADAR REMOTE SENSING TECHNIQUES FOR MONITORING INVASIVE WEEDS

Invasive plant species have been identified as major threats to biodiversity and the survival of native species and ecosystems. This study is to effectively identify the invasive weed, namely African Olives, within the Hawkesbury Nepean catchment in Sydney's west. Spectral analysis using airborne hyperspectral imagery and polarimetric COSMO-SKYMED X-band data are utilized in this study to monitor the occurrence of an invasive weed species, African Olive. Field surveys, as well as, the vegetation subgroup maps were used to validate the results.
