Driven by the need for national data as part of the 2011 boreal caribou science assessment, a standardized methodology was developed and implemented to create a single geospatial dataset representing anthropogenic disturbances across a significant portion of Canada's boreal ecosystem. The boreal ecosystem anthropogenic disturbances BEAD data is a vector disturbance dataset of individual linear and polygonal disturbance types that were manually collected through the interpretation of 2008 to 2010 Landsat imagery at a 1:50,000 viewing scale. Summary results identified a total polygonal anthropogenic disturbance footprint of approximately 24 million ha with forest cutblocks accounting for more than 60 % of mapped polygonal disturbance. Linear disturbance features across the boreal total approximately 600,000 km with roads and seismic exploration lines contributing to more than 80 % of the mapped linear disturbances. For distribution and use by the public the data was gridded to a 1km resolution product that can easily be incorporated into a wide variety of applications. Each disturbance type was gridded as the total per km2 km2 / km2 for polygonal disturbances and km / km2 for linear disturbances . This product consists of 19 individual raster layers - 16 representing different disturbance types, along with layers representing the total linear and total polygonal disturbances separately and a binary mask layer defining all cells that contain disturbance values
