[HTT19-12] Topographic surveys in Ny-Alesund, Svalbard, and improvement of mapping methods
Keywords:Ny-Alesund, Permafrost, High-resolution mapping
We analyzed altitude slope, aspect, curvature, and solar radiation for the area near the Ny-Alesund Science Village using DEMs produced by the Norwegian Polar Institute. We evaluated the reliability of the terrain analysis using TopoSvalbard satellite images and aerial photographs. We also utilized ground photographs and high-resolution ground mapping with the SfM-MVS method to produce a topographic map of the area. Since legal restrictions on the use of radio frequency in Ny-Alesund limit the use of UAVs, we made a pole camera with stabilizer function, which provides photographs with about 3 mm resolution. Such photographs are useful for very high-resolution mapping for small areas.
