Assessing and Predicting Urban Sprawl in Tizi-Ouzou, Algeria: A GIS and Remote Sensing Approach with CA Markov Model

Lyes Belaid, Nabil Amine

This study aims to assess urbanization in Tizi-Ouzou, Algeria, employing two methodologies. The first involves creating a BAEMOLI map to extract built-up areas using indices such as NDBI OLI, NDVI OLI and MNDWI OLI. The second utilizes supervised classification to analyze urban growth across three time periods: 2009, 2015 and 2021. Initially, we apply the first method to gain a broad visual perspective of urban expansion within the wilaya’s regions. Recognizing its limitations in differentiating between bare land and urban areas, we complement it with the second method, offering a more granular analysis through quantification. This approach enables a precise examination of urbanization trends, supplemented by a future projection via the cellular automata Markov model. Our findings provide detailed insights and interpretations of urban sprawl across six regions in Tizi-Ouzou.
