The soil classification in terms of moisture content and thus determine the drought-prone areas more than others by using private vehicles Photochromic Bandhat satellite Landsat equation, and developed the guide based on the standard variation spectral values visible red and blue of the channel, and applied this directory in the sand dunes environment, it showed the possibility of The main objective of the use of visual space in the rating is to obtain support for the results of the interpretation of aerial photographs using digital analysis techniques, by software prepared for this purpose, which we get from which to collect image of cells in the visual and automatically in the varieties of land cover or in certain subjects This arrangement is in the collection of mock cells under the spectral reflectivity of each mock cell, thereby using multispectral data usually to accomplish classification .
