Abstract

Landsat MSS 7 and False Colour composite were interpreted in the delineation of regional geomorphology, geology, structural and vegetational cover. Mass and material characteristics of the rocks were incorporated in the preparation of an engineering geological map. A net work of road alignments has been proposed based on the Geotechnical Feasibility Index.

Utilisation de la télédétection pour la réalisation d'une cartographie géotechnique a l'échelle régionale

Résumé

Des clichés Landsat MSS 7 et fausses couleurs ont servi à l'interprétation des caractéristiques géomorphologiques, géologiques et à l'étude de la végétation. Les caractéristiques des roches rencontrées ont également été prises en compte pour la cartographie géotechnique. Des tracés routiers ont été proposés en tenant compte de l'ensemble des données géotechniques.
