Remote Sensing of
Coral Reefs

Distribution of coral reefs around the
How much detail can remote sensing
Only suited to coarse and intermediate habitat
Not suited to detailed mapping, aerial photography
consistently more accurate
Satellite imagery getting better; CASI can have accuracies
of 81%, a little more than double any other satellite
Accuracy values after processing

An example of coral bleaching as
seen from space.
Taken from IKONOS satellite imagery with 4m
Future Landsat research offers more promise.
Landsat 8 launched last year has better blue band and
coastal band.
