Urban land use is a dynamic phenomenon, changing with time and space. The information on existing land use and its periodic change is useful for urban planners. Land use and land cover changes in Visakhapatnam city over a period of 70 years were studied using Remote Sensing data. Multi temporal satellite data and GIS provide the potential for mapping and monitoring of urban land use changes. Land use and Land cover maps of Visakhapatnam city for various temporal periods, starting from 1941 to 2009 were prepared using topographical maps of Survey of India and updated by satellite data of IRS-1D LISS-III of 2003 and Cartosat-I satellite data of 2009. These maps were interpreted and land use and land cover changes were identified. Replacement of many agricultural villages by the establishment of steel plant in 1991 and replacement of fishing villages by Gangavaram port in 2005 are the important land use changes in the study area. Reclamation of tidal swamp for port based industries is the major land use change.
