In Figure 8, Shuttle Range Topographic Mission (SRTM) data
was prepared for shaded and relief map for terrain conditions.
This study area is almost flat and fluvial flood plains. The
product generated from SRTM data to topographic analysis is
important for descriptions of soil contacts and structural
features. The perspective of the relief, through the simulations
of different angles of illuminations, gave the shadow of the
relief, giving the impression of concavity and convexity,
allowing the identification of structural features, soil contacts,
erosion zones and other geomorphological features of the study
area.

The landform classification system is based on geomorphologic
principles, i.e., classification on the basis of landforms, and the
dominant processes in operation related to historical processes.
Additional factors, including land use and land cover, were also
used for classification. The final geomorphological map is
presented in Figure 9. Integration of both optical and radar data
was implied for geomorphic landform mapping, in details of
terrain conditions, manmade features and lanuse land cover
around Yangon river bed and around Coastal flood plain
terraces.
5. CONCLUSION
The contribution of TM band 4 was related to the
discrimination of dense mangrove forest from secondary
vegetation of the coastal plateaus, whose spectral response is
mixed with exposed soil produced by human activity and
disaster affected. The JERS-1 SAR data have contributed to the
enhancement of distinct coastal vegetation height, geometry,
Water content, and degraded and regenerating mangrove
Tegions. The Multi temporal SAR product was fundamental in
providing consistent information about the geo-botany
(vegetation and coastal sedimentary environment relationship)
and emerged and submerged coastal geology that cannot be
accomplished from field investigations alone..
