Abstract EN

The regional dimension plays an influential role in formulating urban development trends in the city of al-Ula, which represents the capital of the governorate, and the third largest city in al-Madinah al-Munawwarah region.

therefore, the study aims to evaluate the spatial suitability model for urban development in the city of al-Ula through a spatial analytical methodology that helps in preserving natural resources, and not expanding at their expense, by studying the criteria (possibilities-determinants) of urban development of the city at the present time, and analyzing its spatially impact through what the spatial analyst tools provide within the GIS environment, based on the formulation and determination of the relative weights of weighted overlay criteria, by giving higher weights to the factors affecting the suitability of the land for development.

the study also attempts to shed light on the cartographic stages to evaluate the model, process the data inside it, build the structural model builder, and output the data in a cartographic and tabular form that shows the degrees of land suitability for urban development, and determines its future axes.

the study concludes with presenting the findings of the researcher, then some recommendations that contribute support and making of the developmental decision in the city.
