Fig. 6. Land-cover map of the Kendall Island Bird Sanctuary and Fish Island in the outer Mackenzie Delta, Northwest Territories showing four land-cover classes derived from a supervised classification of Ikonos imagery, as well as areas that were unidentified in the classification, water bodies, and areas that were masked out of the imagery before classification. In addition, areas of wet-sedge low-centered polygon habitat were distinguished from within the non-shrubby lowland habitat by visual pattern analysis of the imagery.
