dc.description.abstractRemote sensing images are of use when it comes to monitoring the growth of urban areas compared to other traditional approaches, as they can provide quick and synoptic views. One of the common approaches is to use spectral indices to extract built-up areas to track the phenomenon of urbanization and change in land use. Several built-up indices, that are derived from remote sensing measurements, are commonly used to characterize the urban growth pattern of cities. In this work, four built-up-indices were compared and analyzed to extract the urban areas in the city of Hassi- Bahbah (Province of Djelfa) from medium resolution remote sensing data (Landsat), namely: Band Ratio for Built-up Area (BRBA), Normalized Built-up Area Index (NBAI), New Built-up Index (NBI), Normalized Difference Built-up Index (NDBI). The reliability of the four indices was measured using confusion matrices and the Kappa coefficient through 50 validation zones mapped using field surveys and photo interpretation. The results showed that the BRBA index obtained the best performance for the extraction of built-up areas and better separation from to bare soil. The approach adopted can be used to assess the phenomenon of urbanization in areas with similar characteristics and to guide possible actions to control this phenomenon.
