Use of Geographical Information System technique to know the distribution Limestone sites in Riyadh province

Mineral wealth is one of the most important sources of income for primary producing countries. This industry is important in developing economic resources and diversifying income streams so that countries do not rely solely on petroleum as their primary source of income. As a result, we are seeing the emergence of geomorphology studies, with scientific results that have economic and technical dimensions, which can be relied upon when implementing development and future plans. The objective of this study has economic dimensions and morphological aspects related to the location of limestone in the Wadi Nisah area, southwest of Riyadh. It is based on a range of modern scientific tools, techniques and geographic information systems (GIS) for identifying and highlighting the presence of this rock type. The researcher has chosen this topic in order to collect spatial and geological information about the limestone in a database and locate limestone that is economically feasible using GIS and remote sensing. The researcher concluded that the Wadi Nisah area is of high economic feasibility, . The researcher recommends that the relevant authorities consider the importance of establishing a cement factory in Wadi Nisah in order to supply the local and regional market with Portland cement and similar products. In addition, modern geomorphological techniques are used to achieve the precision required for data on which we can depend to take the decisions and make assessments for establishing development projects to support the national economy.
