Natural phenomena and human activities are always changing the earth and Knowing about changad information of the earth’s surface is becoming more and more important in monitoring the local, regional and global resources and environments. The large collection of past and present remote sensing images made it possible to analyze spatio-temporal pattern of environmental elements and impacts of human activities in past decades. Meanwhile the modern world needs accurate information about these changes for updating Geospatial Information Systems(GIS) and databases. Detecting and monitoring waste sites is one of the most essential parts of urban management and due to the impact of environmental and economic issues for these sites, they must be monitored continuously and in a scientific manner. In this study, detecting the construction debris around Shahryar during a period of time is studied. In this study, images of 2014 and 2015 Landsat8 are used. In this method, and after some pre-processing, using image differencing and spectral indices, change detection map is produced. The overall accuracy of the proposed  method was of the order of 96.41%.
Keywords: Change Detection, Construction Debris, Remote Sensing, Landsat8.
