This dataset of land disturbances of the Upper Peace Region of Alberta is derived from selected Landsat multispectral datasets captured in 5-year intervals from 1985 to 2015. Disturbances were detected through time-series comparison of the selected datasets, classified based on the time of first appearance on the landscape, and then attributed to four major disturbance types:
The disturbance-type data are stacked to create a 4-band TIFF image with each band representing the time-series data for one of the four disturbance types.
