Lakes and reservoirs supplying potable water require protection from contamination. In the area around Istanbul, the threat of such contamination is increasing as settlements locate in water basins. The resultant settlement leads to depletion of forest areas and to air and water pollution. Because this occurs without permission, planning or control, the dense settlement, which leads to the depletion of forest areas, environmental pollution and problems of pollution, also leads to problems of insufficient service areas. The objective of this study is to evaluate potential of high resolution satellite imagery in producing detailed Land Use/Land Cover map of absolute and short protected areas of Elmali water basin. IKONOS 4-meter multi-spectral (MS) sensor data acquired on 26 June 2004 was used in this study. As a result of classification, within the absolute and short range protection zone boundaries, area of the water, forest road, barren and urban categories are obtained as 0.82, 12.2, 0.2, 4.0 and 0.18 square kilometers, respectively. The overall accuracy of the classification was determined to be 84%. The Kappa coefficient was calculated 0.745.
