Preliminary assessment of the uses of sensors and the spectral properties of weed and native species: In Kosciusko National Park, NSW, Australia

摘要

This study aims to establish a proof-of-concept of using optical sensors to detect and determine the spectral properties of weed and native species in Kosciusko National Park (KNP), Australia. This involves interpretation of the spectral profile of the two weeds, namely Orange Hawkweed and Ox-Eye Daisy (in field and in lab), in contrast to their surrounding native vegetation. This paper presents a case study into the applicability of hyperspectral sensors, and discusses the collected spectral profiles. The preliminary results indicate that difference in profiles between the weeds and natives is large, and opens further research into determining if the profile is unique enough to then pick-up with remotely-sensed imagery collected by drones, aircraft, or satellites.
