- Abstract:
-
A 1:4 million-scale color-infrared (CIR) image of AVHRR satellite data was used as a base map. Data for each 1-km AVHRR pixel were selected at the time of maximum greeness from biweekly images from 11 July to 30 August 1993 and 1995.
False color-infrared images display vegetated areas as a gradient of red tones. The brightest red areas are densely vegetated shrublands; moderate red areas are generally well vegetated surfaces, often with tussock tundra, and the dull red to brownish areas are more sparsely vegetated incluing dry tundra, nonacidic tundra, and wet tundra. The darkest black to bluish areas are water. The lightest areas are light-colored bedrock (dolomite or limestone) or light-colored gravel in roads and river floodplains. Lichen covered bedrock (mostly sandstone and conglomerates) is dark grayish green.
- Purpose:
-
Vegetation classification for the Alaska Arctic Vegetation Mapping project.
