Description
Summary: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.In summer 2007, high-resolution aerial images were obtained by mounting a Nikon D200 (visible range) to a helium-filled balloon. Acquisition dates were July 4, 21, 23 and 26, 2007. Flying heights ranged between 620 m and 970 m leading to an average resolution of 0.33 m for the single images. A network of 26 ground control points were set up to calculate image orientation. For more information on the camera system and the local cartesian coordinate system see Scheritz et al. (2008, hdl:10013/epic.30127.d001).25 images were selected to cover the whole island. Images included both nadir and oblique images that resulted in strong color differences between the images that could not be completely corrected. Images were orthorectified ...
