6.28 In order to identify the exact location of the exisiting embankments, the satellite imageries of the study area were analysed. The LISS-III and PAN imageries were procured from National Remote Sensing Agency, Hyderabad and interpreted with the help of Regional Remote Sensing Service Centre, Kharagpur. In the following pages, the False Colour Composite (FCC) images of the entire area are presented in small segments matching with the Survey of India Topo-sheet extents. The corresponding sheet numbers are written over every image for easy identification. Overlain on the FCC images are the existing embankments, marked with different colours, depending upon the corresponding widths. A second set of digitized figures are also presented, which also mark the locations where new embankments are proposed by the Irrigation and Waterways Department, Government of West Bengal.
