Abstract

The oligotrophic coastal waters of Western Australia provide a unique opportunity to apply hyperspectral remote sensing techniques. This project aims to use HyMap images of Rottnest Island to create thematic classification maps of the marine benthic habitats for use as a planning tool by managers and planners. This involves building a spectral reflectance library of the dominant benthic substrates, creating a digital elevation model for the island and classifying the images. Preliminary results have revealed that dominant substrates are spectrally separable and that the Krigging interpolation algorithm results in the most accurate digital elevation model.
