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. On August 08,...

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. On August 08, 2014, high-resolution aerial images were acquired during a helicopter flight using a Nikon D200 in the near infra-red (NIR) range. The internal IR-filter was removed from the camera in a laboratory (LPD LLC, USA). The camera was fitted with a Schneider Kreuznach B+W IR-filter 093 to acquire images in the NIR range, above about 830 nm. Flight distances from the island's surface ranged from c. 400 m to c. 1700 m. In total, 212 images (Appendix A) were used for stereo photogrammetric processing using Agisoft Photoscan (V 1.1.6).
