摘要: Urban sprawl detection and monitoring can be facilitated through the multispectral high resolution Indian Remote sensing Satellite (IRS-P6) images of LISS III IV sensors. The present study makes an attempt to analyse dominant changes that occurred in land-use/land-cover features Mehadrigedda watershed during past three decades (1975-2005). It is found phenomenal increase built-up area from spreading haphazardly into fringe Visakhapatnam metropolis.
