The study was is carried out to determine the possibility of using GIS and Romote Sensing for contributing in the survey of soil through the identification and drawing the units of the map for the soil and calculate their slight relativity.

The study relied on the Landsat 8 Satellite Image for Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) which captured on 07/13/2014 from the USGS site, The study area was truncated by using ERDAS package, choosing the False color Composite RGB (753) to be the best being a specialist to study the soil and minerals.

Some improvements have been made (radiation , spectral and spatial) and depending on Unsupervised classification as well as soil indicators such as soil Color, texture and natural plants in determining the movement paths to select 16 Pedons with 24 auger holes to a depth of 75cm for surveying and isolating soil map units expected in the study area which identified using GPS, The pedons revealed and described geomorphology, according to the Soil Survey Staff , 1999 and selected disturbed soil samples from each horizon for execution the physical and chemical analysis.

depending on the US Modern rating that all pidons within an Entisol order, and classified into two of the suborders , the first Fluvents and great group Torrifluvents and sub group Typic Torrifluvents includes Soil series ME1 , DW56 , TW964 , DM44 , MW3 , TE354 , DW124 , DE47 , DE126 .The second Psamments consist of two great groups are Torripasmments and subgroup Typic Torripasmments involves soil series DE33 , DE34 , DE74 ,TE334 , TW446 .

and quartzipasmments includes sub group Typic quartzipasmments consist of ME1 , DM14.

It was diagnoses nine families and 15 serieses depending on Al-Agidi , (7).

The results showed a variation in spectral reflectivity values both between studied pidons within the same spectral range or between the spectral bands used in this study, reflecting the state of the contrast between the characteristics of soils for studied pidons as well as the variation in susceptibility sensor spectral bands among them.
