Land use and land cover changes due to fast growing cities, are becoming major environmental issues for developing countries. The change analysis of various land use pattern within the city is very important for proper management so that decision makers and planners can take an effective measure. Now-a-days, Satellite based earth observation and monitoring has become a very scientific and effective tool to detect and monitor land use changes. In the present work, an attempt has been made to analyze the temporal land use pattern changes of Chittagong district using Google Earth satellite images and ArcGIS. Chittagong district is a very fast growing port city, located in the south-eastern region of Bangladesh. So to know, its land use changing pattern is much diversified and an important issue for the city planners. In this study, Google earth maps for a time period of 2002 to 2014 are collected for every two years and used for developing the land use maps of Chittagong district. Land use map is developed on the basis of four determinants - urban area, forestland, barren land and water body. From analysis, the result shows that with the increasing years from 2002 to 2014, urban area and barren land is increasing day by day while the forestland is decreasing at an alarming rate. The change of water body is decreasing but the process is a bit slow. These land use maps of Chittagong District observed from the low resolution satellite images are very important for primary level quantification of land use pattern and to show the qualitative land use change of Chittagong district with progressive years.
