 The study aims to develop a high-resolution ecosystem map of terrestrial ecological communities in the intensive monitoring area, IMA, of the Canadian High Arctic Research Station, CHAAS, using a standardized classification of Tundra ecosystems, which will provide an ecological template for designing and implementing ecosystem research, long-term monitoring experiments, and linking local-scale research to regional scales using remote sensing tools and models. The study discusses opportunities and challenges regarding the mapping approach tested for the ecosystem classification and the usefulness of the mapped result for a range of potential applications.
