Harvest Year/Mask 1985-2015
Annual mapping of national level forest harvesting for Canada detected inclusive of 1985 to 2015 from Landsat satellite imagery.
This dataset is composed of two layers: (1) binary harvest mask, and (2) year of harvest disturbance detection. The information outcomes represent 31 years of harvesting activity in Canada’s forests, derived from a single, consistent, spatially-explicit data source in an automated manner. Time series of Landsat data with 30-m spatial resolution were used to characterize national trends in stand replacing forest disturbances, including those attributed to harvest for the period 1985–2015 for Canada's 650 million hectare forested ecosystems (Hermosilla et al. 2016). See references below for an overview regarding the data, image processing, and time-series change detection methods applied, as well as information on independent accuracy assessment of the data.

- The data represents stand replacing disturbances that occurred between 1985 and 2010. Other changes may be present that are not portrayed here. To avoid confusion in areas with dynamic agricultural land use, an agricultural mask was used in the change detection process. Therefore, changes near agricultural areas may not be captured due to use of this exclusionary mask. An image compositing window of August 1 ± 30 days was used to generate the best-available-pixel (BAP) image composites used as the source data for change detection and attribution. As a result, changes occurring after August 31 may not always be mapped to the correct year; however a national independent accuracy assessment indicated that 97.7% of changes were labelled to within ± 1 year (Hermosilla et al. 2016; http://www.tandfonline.com/doi/full/10.1080/17538947.2016.118767 )
