INVESTIGATION OF METHODS OF DETERMINING TERRAIN CONDITIONS BY INTERPRETATION OF VEGETATION FROM AERIAL PHOTOGRAPHY. PART 3. INTERPRETATION OF VEGETATION ON AERIAL PHOTOGRAPHS OF THE ARCTIC AND SUB-ARCTIC REGIONS
Abstract
Photographs were taken over 3 regions: lowlands and plains, mountains, and shield areas. The lowland area, the drainage basins of the Albany and Attawapiskat Rivers, James Bay, illustrates terrain conditions representative of a large part of the subarctic lowlands in North America and USSR. The terrain conditions of the Canadian Rocky Mountains, serving as an example of mountains in this region, and the subarctic and arctic mountains were investigated. The shield areas mentioned are the Canadian, Baltic, Anabar, and Aldan. The latter 2 are in Siberia. Landing conditions on arctic beaches, white objects in the arctic which are neither snow nor ice, terrain conditions in the spruce-forest region of Manatuska Valley, Alaska, and those of a peat-cutting area in the subarctic spruce-fir forest, were observed. A set of 20 superposable maps of USSR are included.
