Automatic Road Detection using Satellite Images

Linear feature extraction has always been a center of attraction for various applications such as urban planning, GIS database update, disaster management, tracking and monitoring and so on. So an accurately extracted image containing roads as the principle component is the need of the hour. With the development of various satellite image processing technologies, the extraction or mapping of linear features such as roads from high resolution satellites images has gained huge momentum in the recent past. This paper presents an automated road detection method using image processing techniques such as connected components analysis and Hough transform. Proposed method is unaffected by noises present in the image. Proposed method was tested on satellite image of developed urban site. Correctness and completeness of 95.6% and 90.5%, respectively were achieved.
