Although atmospheric
Rayleigh scattering seems insuperable, improved
spectral resolution of sensors may still offer an opportunity
to enhance the capability of sensors to discriminate between
habitats and take full advantage of the high spatial resolution
now available. We adopted a simple textural filter to
utilise the additional spatial information in the IKONOS
data, and while developments of this technique may yield
slightly improved accuracies, the data presented here suggest
that it is unlikely that satellite sensors can deliver finelevel
habitat discrimination without better spectral resolution.
