Canada Access: Combined
(2010-09-13) The Canada Access dataset is a compilation of data sources showing areas of Canada that have undergone anthropogenic disturbance.
It was created to facilitate analysis of areas undergoing anthropogenic disturbance throughout Canada. The dataset combines roads, mines and reservoirs across Canada. Furthermore, all anthropogenic features across Canada which are visible on Landsat imagery (at 28.5m resolution) are included. Examples of these features include linear features such as pipelines, power lines and seismic lines, and polygon features may include areas disturbed due to forest harvesting, oil/gas wells and conversion to agricultural/settlement areas. The description of the anthropogenic change feature is not identified in the dataset.
