High-resolution land cover mapping is needed in the heterogeneous arctic landscapes that change land surface parameters over a range of a few meters. Polygonal tundra on Samoylov Island features a network of dry polygonal rims interspersed with patches of wet tundra and polygon ponds. We obtained su...

High-resolution land cover mapping is needed in the heterogeneous arctic landscapes that change land surface parameters over a range of a few meters. Polygonal tundra on Samoylov Island features a network of dry polygonal rims interspersed with patches of wet tundra and polygon ponds. We obtained sub-meter resolution aerial images of Samoylov Island by mounting a Canon PowerShot S3 IS on a helium filled balloon. Images were acquired in the visibile (RGB) range on August 25, 2006. In total, 60 images (Appendix A) were used for stereo photogrammetric processing using Agisoft Photoscan (V 1.1.6). The decisive criteria for image selection were the absence of clouds and the image sharpness. Only pictures from the central part of the island met these conditions. Camera positions for raw image alignment were estimated by the software due to the lack of an internal GPS log. After image alignment, all points with a reprojection error greater than 0.5 pixels were deleted from the raw point cloud. Since there were no ... |
