Abstract


In order to better constrain the utility of multispectral datasets in the characterization of surface materials, Landsat 8 data were evaluated in the discrimination of geological classes in KISANTU and its vicinity. Ground-based measurements collected from the study area highlight the importance of limestone in that area. The spatial distribution of exposed lithologies in the study area was determined through an image resulting from a band ratio (band 7/band 6) that shows the distribution of clays coming from the alteration of the rocks below; and another image using a band ratio transform (band 6/band 7) to identify limestone. Despite some shortcomings coming from the unsupervised classification, the merging of band ratio and the principal component analyze gives an overall representation of the spatial distribution of exposed geological materials in the study area.

Author Keywords: Band ratio, Principal component analyze, Lithology, Reflectance.


Abstract: (french)


Les analyses des images satellitaires Landsat 8 nous ont permis d’actualiser et compléter la cartographie lithologique de la cité de KISANTU et ses environs reposant sur les schisto-calcaires représentés d’une part par les faisceaux du Bangu et d’autre part par ceux de la Lukunga. Les rapports de bandes 7/6, 6/7 et les analyses en composantes principales des images originales, couplés à des données bibliographiques et de terrain ont d’une part permis d’avoir des cartographies monolithologiques de cette zone et d’autre part permis de valider les résultats obtenus après traitements des données satellitales.

Author Keywords: Rapport de bandes, Analyse en composante principale, Lithologie, Reflectance.
