A circa 2007 land cover dataset over Phase 1, and a circa 2010 land cover dataset over Phase 2 and Phase 3 (EOSD_c2007_c2010_Extents), of the Northwest Territories Taiga Plains Ecozone study area provides updated information on forest conditions (i.e., general vegetative composition and density) and is used in subsequent work for generating large area maps of forest inventory information, including the Satellite Vegetation Inventory and the Multisource Vegetation Inventory. Outside of the c.2007/2010 extents, is the original circa 2000 EOSD dataset. More information on the c.2000 EOSD product can be found at: http://www.nrcan.gc.ca/forests/measuring-reporting/remote-sensing/13433 Information on the Multisource Vegetation Inventory project can be found at: http://www.nrcan.gc.ca/forests/measuring-reporting/remote-sensing/13441
