Abstract
Abstract Data from black and white aerial photographs (1974–75), Infrared colour (IRC) aerial photographs (1983–84), Landsat Multispectral Scanner (MSS) of 1984 and Landsat Thematic Mapper (TM) of 1987–88 are used to locate and measure the existing coastal shrimp fanning areas of selected sites and finally to find out the sequential changes in time perspective in order to explain spatial changes for better planning and scientific management. The shrimp farming and mangrove forest areas are identified and located by remote sensing techniques. The Landsat (MSS & TM) data are used to delineate the surface feature of the coastal area. Infrared colour (IRC) aerial photographs provided most revealing information. Sequential aerial photographs provided information on change in time and places. This study reveals that the shrimp farming areas are expanding through destruction of the mangrove forest of Chokoria Sundarban and agricultural land of Rampai and Paikgachha area. For scientific development of the coastal...
