Abstract
The water crisis is one of the most important problems of the world, especially in Iran. Thus in this study, spectral behavioral features of Saltwater (The Oman sea) was compared with fresh water by using satellite images of Landsat. For evaluation, the optimum index factor (OIF) technique and statistical values such as correlation and standard deviation are used. Based on the results obtained from OIF, the highest value of OIF is 61.35906 with the first rank which is recorded in the band combination of 5-4-1 (correlation coefficient 2.280219and standard deviation 139.9121). Thus, this combination has the highest amount of information with least amount of duplication. Optimum index factor on qualitative technique scan is the best virtual color image to provide targeted area.
