Abstract
The area of study is located in the western center of the city of Najaf, and its borders are 32o 8 '- 31o 39' 16 "N 44o 30 '15" - 43o 47' 11 "E It covers an area of 1970 square kilometers inside the sea of Najaf. This study was conducted to investigate the possibility of using remote sensing techniques and geographic information systems (GIS) to contribute to soil survey operations by determining and mapping the soil map units and calculating their spectral reflectivity. The study area was cut by using the ERDAS Imagine 2013 satellite satellite program for Landsat 8 and OLI + TIMR, which was captured on 2014-7-13 by the USGS, and by choosing the RGB color spectrum (753) Soil, and metal, after some improvements (radiation, spectroscopy and spatial), the unclassified classification, as well as the field observations as well as the topography, were used to identify the pathways of movement and movement to determine the location of the Pedons, which numbered 16 boreons with 24 holes of 75cm To clear and isolate map units The soil was found to be in the Entisol category and was classified into two types of cultivars, according to the Soil Survey staff, 1999, and samples of disturbed soil were obtained from each horizon for the purpose of conducting physical and chemical analysis. Below the rank, the first Fluvents and the Great Group Torrifluvents are under the Typic Torrifluvents group. The second Psamments include the first two groups, the Torripsamments, the Typic Torripsamments, the other Quartzipsamments, and the Typic quartzipsamments, with nine families and 15 series depending on the Al-Agidi proposal. The results showed that there was a heterogeneity in the spectral reflectivity values between the study diodes within the spectral range or between the spectral bands used, reflecting the state of contrast between the characteristics of the soil of the study diodes as well as the variation in the susceptibility of spectral beams to each other.
