the output image was used to carry out geometric correction for the historical tocarry satellite image of ETM+ and TM, using the image-to-image correction method [30]. the ETM+ and TM image wre correction using second order polynomial transformation with RMS values of less than one pixel. All image were reampled by the NN method to 30 m.pixel size, regis tered in the Jordan Tranverse Mercator (JTM) projection and cliped to the borders of the study area
