Application des indices de télédétection à la cartographie des zones urbaines et des sols nus : Cas de la ville de Guelma (Nord-est de L'Algérie)

In recent years, areas of vegetation and farmland in peripheral areas of the city of Guelma have declined in relation to urban sprawl and gradual subdivision of soils for construction purposes. In this context, it is necessary today to map these areas that play an important role in urban development and environmental quality. The objective of this study is the application of remote sensing indices to map the built-up lands and bare soil in the city of Guelma from the satellite image of the Landsat 8 program of 23 July 2018.The present study is based on bare soil and urban land indexes such as: NDBI, EBBI, UI and NDBaI. The result obtained shows that the NDBI index presents an acceptable result for mapping urban land and bare soil. This method can be used to monitor land use in the city of Guelma.
