The FINEGIS F2 data set is located in Northern Greenland upstream of the northern branch of the 79° North close to the ice divide. On average the 3D horizon spans an area of 105 x 65 km and has an age of 52.2 ± 2.7 ka (thousand years). The data resemble two cylindrical fold units, which are located in the lower third of the ice column.

The 3D horizon and traced radar lines are provided in three different data formats (because this data set contains overturning folds, we do not provide Digital Elevation Models):1. ASCII format of the point cloud of the 3D horizons (meshes.dat) or traced radar lines (line.dat) in the xyz format, where x and y represent the coordinates and z the elevation in meters.2. GoCAD (Geological Objects: The 3D horizons (meshes) are stored in triangulated surfaces (.ts) and the traced radar lines as polylines (.pl).
