The document discusses the implementation and use of a Geographic Information System (GIS) by the Saudi Industrial Property Authority (Modon) to manage industrial cities in Saudi Arabia. It provides context on GIS and its benefits, such as faster procedures, increased efficiency, and automated tasks. Modon uses GIS to integrate spatial data with its e-services to effectively plan, allocate industrial land, and manage properties. The paper reviews GIS examples in Saudi Arabia and how Modon can apply GIS technologies successfully to optimize processes and support decision making regarding land management in industrial cities.
