Canada Landsat Disturbance (CanLaD) – Including Forest Insect Pest

This data publication includes three map datasets: Detailed annual disturbance maps – Forty raster layers mapping Canadian forest disturbance types from 1985 to 2024 at a 30m resolution. Latest disturbance type and latest disturbance year maps – A simplified version for enhanced usability, consisting of three rasters that represent the most recent disturbance type and year (starting and ending). Latest Landsat time series Julian day map – A raster capturing the latest Julian day for each pixel in the time series, where the Julian day represents the number of days elapsed since January 1, 1970. 2025 Update Changes: For the update of 2025, an additional post-processing step was performed to clean the annual data. The post-processing includes: (1) To limit false positives in defoliation classes, additional satellite data sources were used (Sentinel-2). (2) Correction of certain fire pixels in areas known to be heavily impacted by the hemlock looper. (3) Correction of pixels at disturbance boundaries. (4) In areas without forestry operations (the non-commercial northern part of Canada and national parks), visual inspection and correction as needed of pixels classified as forest…
