摘要

The purpose of this model application is to asses the suitability for cultivation of a 50,000 faddans in Sinai Peninsula by using GIS spatial analyst modeling technique which is considered a unique powerful tool for spatial analysis and decision making. This specific analysis model was accomplished through investigating three main points. The first focused on the slope of land topography, water resources, and the existing roads. The second dealt with the reconnaissance soil survey this comprised of the morphological description of the investigated soil profiles and the chemical and physical properties of the soils. Then the third one was the development of a spatial analyst model to asses the soil potentiality for cultivation. Typically, this model contains several processes, which are chained together in such a way that output from one process becomes input at next level. The major output of the model is a soil potentiality map. The output cultivation land suitability map shows the relative suitability of land in a planning area for cultivation-type development, thus helping the decision makers to plan the area for cultivation with all necessary instructions and managements.
