الملخص EN

Cities in the Kingdom of Saudi Arabia witnessed a great urban expansion due to the natural increase in the population or due to internal migration to it from villages and desertions.

It relied on the spatial analysis method using remote sensing technology and geographic information systems (GIS) by obtaining two satellite images from the USGS site, the first from the Landsat 5 satellite on August 18-1984 AD and with the TM sensor.

The second was from the Landsat 8 satellite on August 13, 2017, with the OLI sensor.

The improvement, correction, processing and analysis operations were carried out using the ERDAS IMGIN 2014 program and ARC GIS 10.5.

The study found that the urban mass has doubled nearly fourfold, from 31 km 2 in 1984 AD to 97 km 2 in 2017.

The study also found that the largest urban expansion was towards the southwest, with a distance of 34 km, then the northeast with a length of 33 km.

As for the west and east, the expansion of the city stopped due to the presence of the natural barrier, which is the presence of mountains.
