visually for land use land cover condition of Yangon river in 
and around and City area.

In Figure 5, Landsat Satellite acquired with ETM-- Sensor for 
the study area. After composite of FCC 432 combination was 
done and carefully analyzed for landuse landcover extended 
and urban, sub-urban sprawled areas.

In May 2 of 2008, Myanmar was seriously hit by Cyclone 
Nargis and there was damaged to coastal mangrove areas and 
its biodiversity system in and around of Yangon river terraces 
(see figure 6). 
4.2 Interpretation and terrain analysis from RADAR data 
  
Figure 7. JERS 1 SAR Multi Temporal image of study area 
In Figure 7, Japan Earth Observation Satellite was taken 
Synthetic Aperture Radar (SAR) imagery for 3 different 
seasons of around 1996. Coastal surveillance and 
environmental monitoring has motivated the development of 
automatized feature extraction tools using remote sensing data. 
Target detection by Synthetic Aperture Radar (SAR) has been 
extensively studied in recent years. In carefully interpretation 
from SAR Imagery, river boundary and coast line field give 
high radar backscattered energy due to their high surface for 
roughness. Strong waves and tides (surfing in particular) make 
seawater very rough which leads to very high radar 
backscattered energy at places. Coastline is therefore masked at 
places between land and water boundary.
