The post-classification comparison of change detection was carried out using GIS, producing change maps for understanding
the spatial pattern of change between years (Fig. 3). Table 4 shows a summary of the major LULC conversions,
namely ‘from–to’ information, which occurred during the study period. As indicated, the majority of urban land was acquired
by converting areas that were previously agricultural land, vegetation, water bodies or low-lying areas, suggesting the
existence of increased pressure on natural resources in Greater Dhaka to meet the increasing demand for urban land.
