Land Disturbances of the Upper Peace Region of Alberta, Derived from 1985 to 2015 Landsat Multispectral Data (image data, TIFF format)

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: 

1. energy footprints (oil, gas, and coal mining activities),
2. non-energy footprints (other infrastructure),
3. cutblocks (primarily forest harvesting), and
4. wildfire.

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.
