Summary

This dataset shows the extent of buffered (500m) anthropogenic disturbance in the Broadback River Watershed region based on Landsat imagery from 1980 to 2015.

Description

This dataset maps the extent of buffered anthropogenic disturbance in the greater Broadback River watershed based on Landsat imagery from the 1980 to 2015 time period. This dataset is based on the GFWC polygon and linear disturbance datasets for the Broadback Watershed region. The features from each of those datasets were buffered by 500 m to account for an ecological footprint and combined to create this dataset for disturbance by 5-year time periods beginning from 1980 to 2015.

Data Quality 

Lineage 

Lineage statement
This dataset is originally based on Global Forest Watch Canada polygonal and linear disturbance datasets for the Broadback River watershed region. All disturbances were buffered by 500m and overlapping disturbances were clipped so that only the earliest date of the disturbance is mapped.
