Change Detection Methods Using Band Ratio and Raster to Vector Transform

LandSat Satellite ETM+ images have been analyzed to detect changes in Euphrates river boundaries area at the middle of Iraqi country from the year 1990 to the year 2001. Changes are determined by applying the rationing method on the bands 3 and 5 then using Raster to Vector (R V)Transform method .GIS 9.1 program is used to apply the rationing method and Raster to Vector (R V)Transform technique then determined the results (changes in boundaries area were calculated)
