Photogrammetrical 3D-mapping of Kilen - a complex corner of eastern North Greenland

The Carboniferous – Palaeocene Wandel Sea Basin is exposed in easternmost North Greenland (Håkansson and Stemmerik 1989). In the southern part of the basin a structurally complex succession of Mesozoic sediments is exposed on Kilen: a 300 km2 semi-nunatak (Fig. 1). Kilen was previously mapped during expeditions in 1980 and 1985 (Pedersen, 1989; Håkansson et al., 1993) but
further mapping was needed to gain a new and more accurate understanding of the complex geology. The oblique photogrammetry method (Dueholm, 1993; Vosgerau et al. 2010; Sørensen, 2012) is an ideal way to obtain high quality 3D data in remote areas with difficult logistic conditions and short field seasons, such as in North Greenland. Here, for the first time, oblique photogrammetry has been combined with 3D structural modeling to better understand the complex geological evolution of the area.
