Abstract
This study aims to identify the urban growth in Al-Baha city in the Kingdom of Saudi Arabia by observing the urban growth and its trends and detecting the change in urban growth in Al-Baha city using multi-spectral remote sensing data (RS) and geographic information systems (GIS) between 2005 and 2020. To achieve this study’s objectives, the techniques of geographic information systems and remote sensing was employed to process and analyze the satellite images of the SPOT5/7 satellite for the years 2005, 2010, 2015, and 2020.
The study applied the following methods: unsupervised classification of the satellite images, change detection of urbanization, and the nearest neighbor coefficient was calculated to study the spatial distribution of urbanization. The study also calculated the Pearson correlation coefficient to clarify the relationship between the increase in population and increase urban growth.
The results of the study revealed that the urbanization Al-Baha city is characterized by a remarkable slowness in its speed and areas, and the mountainous nature dominates the city’s topography. The urban areas in Al-Baha city reached (2.15%) in 2005, (2.64%) in 2010, (3.08%) in 2015, and the highest percentage in 2020 when it reached (3.29%) of the total area of the city. However, it also appeared that the percentage of detecting change in urbanization ranged from (0.49%) in 2010 to (0.44%) in 2015 and then (0.29%) in 2020.
The study recommended that the need to monitor urban growth in Al-Baha city, and draw maps of urbanization change during periods time to know and identify urban excesses, and control them or monitor the efficiency and consistency of development plans in the city.
