The study focus on land use land cover, drainage network, stream ordering and age of the streams in the extended area of Bannerghatta National Park. The drainage network and micro watersheds are developed for the study, using ArcGIS by manually the drainage network and micro watersheds delineated and for these micro watersheds, bifurcation ratio was found using the Strahler method of stream order to find the age of the streams and also the drainage network and micro watersheds are extracted using ArcHyro tools. In the study area we have tried to understand the landuse and landcover by supervised classification using maximum likely hood classifier with the ENVI software.
