Canada-wide Landsat-based 30-m resolution product of disturbance detection prior to 1984

This is the final version of the pre-Canlad data product, covering Canada's forest disturbances between 1965 and 1984

Up to date dataset desciption and metadata can be found here:

There are 3 layers:
 1. canlad_1965_1984_disturbanceYear.tif
  Predicted fire/harvest year between 1965 and 1984. This is the result of a final post-processing
  step where we further corrected the FIRE years if:
    - predicted fire year was CONNECTED to a CORRECTED fire year within 5kms (same pixel patch)
    - the difference between predicted and corrected years was equalt to or less than 5 years
    - only fire was corrected

 2. canlad_1965_1984_disturbanceType.tif
  Predicted disturbance type
    1 = no change (false detection)
    2 = fire
    3 = harvest
    4 = insect (no year available for insects)

 3. canlad_1965_1984_correctionMask.tif
  Correction mask. The model predictions (disturbance type + disturbance year) were corrected 
  with auxiliary data (mostly the CNFDB + provincial forest inventories) whenever this data 
  was available. Only pixels where our models detected a disturbance were corrected (i.e. if
  predicted disturbance was 1 (no change) the disturbance was not corrected)
    0 = no correction
    1 = corrected fire
    2 = corrected harvest
