has been influenced by littoral drift as a long-term coastal dynamic 
process near Mangalore. Similarly the sediment dispersion pattern 
for entire Karnataka coast as observed through Bhaskara II data for 
January 1982 has been illustrated through Figure 4. The seawater 
has extremely low absorption in Landsat MSS Band 4 and allows 
pronounced demarcation of sediment dispersion. 
CONCLUSION 
All the aerospace data provide: major geology and geomorphic 
features of Karnataka coast. The sequential coverage of Karnataka 
coast through temporal nature of aerospace data has valuable tool 
for monitoring sediment dispersion and morphological changes 
along coastline. The following are the major concluding remarks: 
4&5 The coastline demarcation is identical through all aerospace 
data. 
ææ The details of coastal feature are well documented through 
Aerial photograph. ; 
«& The coastal drainage is better delineated over Landsat 
imagery. 
2 4: The morphological changes along estuary, spit and offshore 
bar are precisely delineated over Salyut 7 space photograph 
and Bhaskara II data. 
#55 The sediment dispersion along offshore area is precisely 
demarcated over visible range Landsat MSS Bhaskara II and 
IRS data. 
æ æ The digital analysis of latest satellite data OCEANSAT, IRS 
LISS III and Landsat (CZSS) may provide coastal features 
upto better accuracy in conjunction with relevant ground truth 
data.
