This map was produced from high resolution airborne data (CASI), acquired in eight bands at 1 m spatial resolution. Overall accuracy of map = 78%

Further details on the production of this map are given in Green et al. (1998), Journal of coastal Research, 14: 433-443.

  1. = Area of Rhizophora mangle expansion.
  2. = Mangrove zonation.
  3. = Path (3 m wide) through mangrove to jetty. 
  4. = Cleared mangrove (domestic waste dump).
