Coral reefs are endangered world-wide by devastating fishing methods
(overfishing, dynamite and cyanide fishery), pollution, tourism, environmental
changes and bleaching. The aim of this project is to monitor coral reefs and
associated ecosystems (mangroves, sea-grass beds) by integrating different
remote sensing data with spectral libraries and field measurements. The study
area is Fordate, a small island to the northeast of Tanimbar, Indonesia. The
monitoring system under development will enable not only the mapping of the
coral reefs but also the localisation of those parts of the reefs that are most
affected by degradation. A first test with hyperspectral data from the
CHRIS/PROBA sensor shows promising results for the discrimination of different
bottom-types on the Pulau Nukaha patch reef east of Fordate. Further field
sampling and spectral measurements are needed to validate this preliminary
classification.
