Land cover map along the Inuvik-Tuktoyaktuk Highway corridor

This land cover map was developed using isodata unsupervised classification method based on two SPOT 4 scenes (both acquired on 4 September 2006) and one SPOT 5 scene (acquired on 27 August 2007). The ITH corridor was classified into 14 land cover types at 20 m spatial resolution. CODE DESCRIPTIONS: 0-Water bodies or outside the map area; 1-Forest dominated by coniferous trees, mainly spruce; 2-Forest dominated by deciduous trees; 3-Shrub with sparse trees; 4-High and dense shrubs (>1.0m); 5-Medium to high shrubs (0.5-1.0m); 6-Medium height shrubs (about 0.5m); 7-Sparse shrubs in slopes; 8-Sedge/shrub low lands; 9-Shrub/sedge polygons; 10-Wetland with small water bodies, usually wide trenches; 11-Seasonally flooded wetland, usually near lake shores; 12-Mixture of water and land, usually along lake shores; 13-Barren land (non-vegetated area, streets, roads, airports). The image is in 8 bits (or 1 byte) binary format (0-13) containing 7863 lines and 5182 pixels. The projection is in UTM 8W D122 at 20 m spatial resolution (Upper left: 513660 E,7734000 N; Lower right: 617300 E, 7576740 N).
