英文摘要	The objectives of this study are to produce a physiographic soil map with correlated attributes to be a base for extra modifiers within the land information system. This integrated data will serve the purposes of land use planning, precision farming practices and to be applied in other areas using the extrapolation approach. The Satellite data of EgyptSat-1 were projected on an area of Middle Egypt that represents unique physiographic features over portions of Beni Suef, El Fayoum, Helwan, and October Provinces. The spectral signatures of the land patterns were delineated by the visual interpretation using the physiographic approach, while soil taxa were categorized according to the key of Soil Taxonomy (USDA, 2010), resulting in two landscape categories. The first category includes older and developed parent materials, covering the following units: (a) Pediplains of residual soils over limestone parent rock, having soils of Lithic Haplocalcids, loamy skeletal. (b) Terraced old alluvial plains represent the formerly deposited alluvium that preceded the recent one of the River Nile alluvium. They includes soils of Typic Calcigypsids, loamy skeletal and old alluvial plain but are currently managed under cultivation. The soils are dominated by Typic Haplocalcids, loamy skeletal. (c) Wadis that were shaped by the paleodrainage erosion, are currently subjected to the seasonal flush flooding and are sparsely vegetated including soils of Typic Torrifluvents, lamy skeletal (calcareous); Typic Torriorthents, sandy skeletal, and Typic Torriorthents, sandy. (d) Aeolian plain "partly cultivated'' includes soils of Typic Torripsamments (calcareous). The second category is a recent River Nile alluvium that formed the following units: (a) Terraced recent alluvial plain "cultivated'' includes soils of Entic Calcitorrerts, fine and Typic Haplotorrerts fine. (b) Recent flat alluvial plain includes soils of Typic Haplotorrerts, fine. (c) Meandering belt is aligning the River Nile course with courser sediments comparing to the recent alluvial plains. This belt is sub divided as levees that have soils of Typic Torriorthents, fine lomy; point bars with soils of Typic Torriorthents, coarse lomy; river banks with soils of Typic Torriorthents, coarse lomy; bow bars with Typic Torriorthents, sandy and Typic Torriorthents, coarse loamy and meander scars with soils of Typic Torriorthents, sandy. All these taxonomic classes are hyperthermic, being developed under the hyperthermic temperature regime within an aridic moisture regime.
