ABSTRACT: In this paper we present a stereo feature-based method using SIFT (Scale-invariant feature transform) descriptors. We use automatic feature extractors, matching algorithms between images and techniques to produce a DTM (Digital Terrain Model) using convergent shots of an ice patch. The geomorphologic structure observed in this study is the Jou Negro ice patch (Cantabrian Mountain, Spain).
Keywords: Geomorphology, Close - Range Photogrammetry, DTM, SIFT.
