Land Cover Classification of Bangalore Metro Using Satellite Imageries-A Comparative Study

Dr. Malini A. Shetty, Prof. R. K. Somashekar

Abstract :

Land Use is an major element in temporal studies of urban imagery, its precise and revised information is indispensable for understanding the environmental consequences of corresponding changes. Impervious surface ratio (ISR) and green cover ratio (GCR are important elements in determining urban environments, which can be employed to assess urban flood phenomenon, vegetation percentage. In the current study temporal study of BBMP is made by procuring satellite imagery 0f 1992, 2000, 2005 and 2010. The imageries are classified into four classes like Water, Built ups, Vegetation and Others by superwised classification. . The overall classification accuracy of 90.56% was achieved for the four urban land cover types. The different imageries from 1992 to 2010 showed phenomenal variation in vegetation cover over the years. The Green cover shows initial increase from 1992 to 2000 and then we could observe rapid depletion from 2005 to 2010. The Impervious surface ratio shows more than 50% increase from 1992 to 2010 and the increase is more prominent in the periphery of the city.
