Detection of Land Cover of Dhaka City from Satellite Imageries

Land cover detection using remote sensing technology is rare in Bangladesh. Land cover data acquisition in shortest time with least manpower can be done by remote sensing technology. Methodology used in this book can be applied for whole metropolitan area which could be a guideline for urban planning. This study is an attempt to measure the exact size of land cover classes of a portion of Dhaka using GIS and remote sensing technology. This will lead to the determination of the exact proportion of areas given to different category of land uses. IKONOS image was used in classification process. The total study area was divided into 4 major Land covers (open space, vegetation, built up area and water body). Then the area under each land cover was determined.
