Geological and Structural Mapping of the Ouaddaï Massif using Landsat and Radar Data
The aim of the work was to produce a geological and structural map of the Ouaddai massif using landsat and radar data. We used landsat-8 images to extract the lithological map (colour composition and ratio bands) and PALSAR DEM radar to extract the lineament map (using different filters). For the radar sensor, a total of 2188 lineaments were detected and extracted, with two main rock fracturing directions (ESE-WNW (90° to 115°) and NE-SW (45° to 65°)).
