Land Disturbance Classification from Landsat Imagery in Cold Lake Oil Sands

Alberta's Cold Lake oil sands region provides a dataset of vegetation loss and land disturbance classified into nine categories for 2010-2011. The Government of Alberta produced this data using Landsat multispectral imagery and land cover classification to support regional planning under the Lower Athabasca Regional Plan. It serves as baseline information for monitoring anthropogenic impacts from oil and gas, forestry, and agriculture.

Use Cases

• Detect and classify vegetation loss into categories like 'exposed land/cut blocks' or 'transitional bare surfaces' using the 9-class scheme.
• Analyze spatial patterns of anthropogenic disturbance from infrastructure related to oil and gas exploration across the defined township and range grid.
• Establish a baseline for vegetation recovery monitoring by comparing the 2010 and 2011 classified imagery.
• Map specific land cover types such as 'shrub land', 'grassland', and 'agricultural areas' for regional ecological assessments.

Strengths

• Classified data derived from Landsat multispectral imagery for two consecutive years (2010 and 2011).
• Disturbance categories are specifically defined for the oil sands context, including classes for developed areas and transitional surfaces.

Limitations

• Data is temporally limited to a two-year snapshot (2010-2011), lacking a longer time series for trend analysis.
• The spatial scope is restricted to a specific administrative area (Townships 56-69, Ranges 1-11 W4M) within Alberta.
