In this study, remote sensing technology and Geographic Information Systems (GIs) were applied as a powerful and effective tool to quantify and spatially characterize land cover of the Bozcaada Island in Turkey by using Landsat 7 ETM data with slope and aspect data. Rectification and classification steps of digital image processing were applied to Landsat 7 ETM image. 1/25000 scaled standard topographic maps were digitized in order to produce digital Elevation Model (DEM) of the island. Slope and aspect maps were derived by using the DEM. Previously derived slope and aspect maps were overlain on the classified image to delineate problematic areas of island for urbanization in GIs environment. Finally, information serving to the development of the island by analyzing slope and aspect data is obtained. Furthermore, the study attempted to demonstrate the potentials and effectiveness of remotely sensed data in the interpretation of environmental issues.
