Today, spatial data is more readily available than ever before (Maitra, 2001). Updated soil surveys are considered quite helpful for planning, developing monitoring and for the sustainable management of the limited agricultural soils available in the study area. One of the main aims of this study is to identify, characterize and map the major soils in the study area(s) following a geopedologic approach. Therefore, all mapping units were digitized in vector mode, and then those digitized maps were loaded into ArcView GIS system for the followed geo-reference spatial analysis.In this research, based on US Soil Taxonomy (1998) and the manifested information about morphological features together with the relevant soil properties, soils of the studied areas fit into two main orders: Entisols and Aridisols and nine taxonomic units (at sub group level) were identified. Nevertheless, the relation between the different soils taxonomic and the physiographic mapping units for each area is obviously occurred.
