Die optimale Nutzung von optischen und Radarbildern ist ein Thema von großem Interesse in der Fernerkundung. Das Hauptziel dieser Studie ist es, das Potenzial der optischen Radarfusion für die lithostrukturelle Kartierung des präkambrischen Grundgebirges in Westafrika zu erforschen. Die räumliche Auflösung des Radarsat-Bandes (50 m) wird auf 15 m verfeinert, indem es durch Wavelet-Transformation mit dem panchromatischen Kanal fusioniert wird, bevor es durch Multiresolutionsanalyse und Wavelet-Transformation mit den ETM+-Bändern 1-5 und 7 von Landsat 7 fusioniert wird. Das Ergebnis ist ein multispektrales optisch-radarisches Bild mit simulierter hoher räumlicher Auflösung (OR). Die visuelle Interpretation der Produkte, die aus den spezifischen thematischen Bildbearbeitungen abgeleitet wurden, ermöglichte es, eine lithostrukturelle Skizze des präkambrischen Grundgebirges zu erstellen. Sie zeigt die großen geologischen Einheiten, Korridore und Unfälle, die für die wichtigsten Bruchrichtungen in der Region charakteristisch sind.
