Land Use Changing Scenario at Kerniganj Thana of Dhaka District Using Remote Sensing and GIS

As Dhaka city is expanding day by day proper land u se planning is an urgent need for its peripheral ar eas like Keraniganj Thana. Rapid land use change has taken place in man y regions Keraniganj Thana over the past two decades due to accelerated industrialization and urbanization. The study was conducted to investigate the land-use pa ttern change of the Keraniganj Thana at Dhaka district over a period of 10 years (1997-2006) by using remote sensing and Geographical Information System (GIS) technologies. The images were processed using ERDAS Imagine 8.4. Both supervised and unsupervised approaches were applied and ground control points were collected using a GPS. Maps were p repared using GIS software. The paper presents the data, methods for land use change detection and results from land cover change detection. The attributes of classified image of 19 97 showed only 3487.73 acres of built-up areas, but in 2006 a rapid increase of built-up areas were found and it was ar ound 4137.05 acres. Urbanization in this area have been mostly unplanned, chaotic and irregular which have led to alarming land, water, air and noise pollution resul ting in much deterioration of environment.
