Abstract: Remote sensing techniques are compared when applied on the survey of mangrove areas. The use of LANDSAT MSS scenes from channels 5 and 7, processed by interactive analyzer, allowed the identification and quantification of this natural resource with great accuracy. The results obtained through this method were compared to panchromatic aerial photography, supported by field experiments and helicopter overflying. This process was very effective in detailed mapping of mangrove areas.
