CLASS-SI provides the colour classes for the Enhanced Satellite Image.
CLASS-CM provides the colour classes for the Classified Map.

Class	CLASS-SI	CLASS-CM	NAME	DESCRIPTION
0			Unclassified	Unclassified
1			Clear Water	Clear water in lakes and rivers
2			Turbid Water	Turbid water in lakes and rivers
3			Submergent Vegetation	Communities of Potamogeton spp.
4			Floating-leaved Vegetation	Dense communities of Sparganium or Nuphar
5a			Emergent Vegetation, Fen	Fibrous floating mats dominated by graminoids (usually Carex aquatilis), or dense meadows of Carex aquatilis or Arctophila fulva in recently drained lake basins. The colour is sample is from the latter
5b			Emergent Vegetation, Fen	Communities of Carex aquatilis and Menyanthes trifoliata
5c			Low-Centre Polygon Fen	This very wet polygonized ground underlain by frozen peat is found in old lake basins and depressions. The vegetation is usually a sparse coverage of emergent graminoids (such as Carex aquatilis, Carex chordorhiza), which gives rise to a Landsat signature very similar to that of other emergent vegetation classes (5a, d). It is a very common feature of tundra further north on the Yukon Coastal Plain. (Note: further information not completed for this vegetation class)
5d			Emergent Vegetation Marsh	Marsh communities dominated by Carex aquatilis
6			Sphagnum Mat	Mats of various Sphagnum mosses underlain by saturated peat
7			Dead Willow, Wet Sedge	Dead willow shrubs with an understory of wet sedge, usually Carex aquatilis. This community forms in lakes that have drained and are in the process of reflooding as permafrost invades and impedes drainage
8			Moist Graminoid Calamagrostis	Meadows dominated by Calamagrostis in drained lake basins. Usually has some scattered medium to tall willow and alder shrubs
9			Moist Graminoid Cottongrass Tussock	Extensive meadows of Eriophorum vaginatum tussocks on uplands underlain by mineral soils
10			Moist Graminoid, Shrub	Moist graminoid communities (8 and 9 above) with higher coverage of shrubs
11			Open Shrub	Variable communities dominated by medium to tall shrubs. Understory communities may be graminoid, low ericaceous shrub, or bryophyte. Often includes scattered spruce
12			Shrub Thicket	Dense stands of medium to tall shrubs, usually willow or alder. The densest stands are found in recently drained lake basins, along rivers, and on levees. Understory species are variable, including Carex aquatilis in recently drained lake basins
13			Open Spruce Forest	Open canopy spruce forests with understory of ericaceous shrubs, cottongrass tussocks, or lichen
14			Lichen Heath	Lichen mats underlain by relatively well-drained soils. Usually found in the form of high-centred or flat-centred polygons
15			Wet Barrens	Unvegetated or sparsely vegetated saturated soils, usually in very recently drained or drying lakes, or along rivers
16			Dry Barrens	Unvegetated or partially vegetated dry soils, most commonly found in exposed alpine areas or gravel bars along rivers. Small areas found in drained lake basins. Some areas of cottongrass tussock tundra may be found in this class if there is a high percentage of frost boils
