Popis
The Satellite View of Alaska, with Shaded Relief map layer is a 200- meter-resolution simulated-natural-color image of Alaska. Vegetation is generally green, with darker greens representing forest and lighter greens representing vegetative tundra. Vegetative tundra regions are composed of shallow rooted plants. Very bright areas, such as snow and ice, are colored blue. The image was produced by combining Landsat Thematic Mapper (TM) imagery from the Landsat 4 and Landsat 5 satellites with relief enhanced by shading.
