Detecting Urbanization using Remotely Sensed Data for evaluating urban planning

The satellite image is used in various fields such as the updating the map, understanding of the urban development. The objectives of this study are new buildings are detected in urban planning area using change of land cover and change of elevation, and urban planning is evaluated using result of the detection. In this study, change of land cover was detected using land cover map from 2002 and 2010. And, difference of elevation was calculated using elevation data 2003 and 2010. New building was detected by the suggested algorithm using land cover change and elevation change. The correct percentage showed 81.9%. Some buildings could not be detected because the accuracy of change detection of land cover was low. Therefore, improving the accuracy of land cover maps would be required. Urban planning area was evaluated from building detection result , road , land prices and population density. Almost building was increased in urban planning area where are depending on land price, density of population and easily accessibility by transportation
