Cumulative Access in Canada's Forest Ecozones (bulletin)
(2010-09-13) This Global Forest Watch Canada study has analyzed the extent to which Canada's forest ecozones have been impacted by significant human activities. GFWC's cumulative access layer was compiled by analyzing Landsat (TM and ETM) satellite images for the period 1988 to 2006. All visible infrastructure and other human activities on the images were mapped and buffered by 500 metres. It is accompanied by a geospatial dataset (see link under "Related Stories" below).
