Abstract

 This paper describes the construction and use of a digital terrain model (DTM) when undertaking a geostructural survey of a subvertical cliff on the Italian coast between Naples and Pozzuoli. In general, the discontinuities are measured directly, but in the case of subvertical cliffs or inaccessible areas, topographic or stereoscopic methods may be used to support traditional survey techniques. The advantages and limitations of this method are discussed.

Résumé

Cet article décrit la réalisation et l'utilisation d'un modèle numérique de terrain (MNT), à l'occasion d'une étude de géologie structurale concernant une falaise de la côte italienne, entre Naples et Pozzuoli. En général les discontinuités sont mesurées directement sur affleurements, mais dans le cas de falaises ou de secteurs inaccessibles, des méthodes topographiques ou stéréoscopiques peuvent être utilisées en appui des méthodes classiques. Les avantages et limites de ces méthodes sont présentés.
