Abstract


Winter crops and open water bodies have a crucial role for agriculture as well as socio-economic development in the Brahmaputra floodplain of northern Bangladesh. In this paper, two multi-date MODIS Aqua imageries of 2003 and 2014 were analysed to classify winter crops and open water bodies during winter periods. Mainly two NDVI images of 2003 and 2014 were used to extract spectral profiles of winter crops and open water bodies that were classified by density slicing and iso-cluster methods. Finally, the classified results show increased trends of winter crops while other crops have decreased tendency. Moreover, an annual growth rate of winter crops and open water was 4% and 1.4% respectively, whereas other crops have negative decreased rate (-2.1%).
