The study aims at the application of Landsat Thematic Mapper (TM) data
for detection and measurement of physical aspects of marine pollution
in the Thane creek region adjoining Bombay city and its suburbs. Coll
ection of marine water samples in the Thane creek region has been sync
hronised with the satellite passes of Landsat. The water samples were
analysed for turbidity, an important physical pollution parameter. An
attempt has been made to establish the relationship between the real t
ime values of the marine pollution parameter (turbidity in this case)
analysed in the laboratory and the digital counts (function of surface
radiance) from the remotely sensed data using statistical technique.
A two step approach has been followed to relate the TM data with the m
arine pollution parameter. The advantage df this methodology in detect
ion and measurement of turbidity is discussed.
