Use remote sensing techniques to estimation of vegetation factor (C) for selected areas in Diyala Governorate

Abstract

This study was conducted on the floor coverings of Diyala Governorate, central Iraq, between latitudes 44 ° 27 ‘31.99 “-45º 25‘11.78”, and 33º 30‘ 8.66 “-34º36‘48.18”, with an area of 10,336,399 km 2. Using the two satellite images of the Landsat 8 satellite OLI_TIRS (rod 36, 37 and path168) captured on 29/4/2018. For the purpose of the NDVI calculation and then a mathematical equation was applied to calculate the values of factor C, the study determined the classification of NDVI values and C factor values to 4 categories The low values of the C factor were concentrated in the presence of forests and orchards with dense vegetation cover (0 - 0.04731), whereas the average values were concentrated in areas with medium density vegetation cover and agricultural areas cultivated with different crops ranged from (0,04732-0.09462) The high values of the vegetation factor were concentrated In the areas of water, mountain ranges and building areas where there is no vegetation cover and ranged between (0.09463-0.18925).
