Cold Lake Oil Sands Quality Evaluation from 2007 Landsat Imagery

The 'Quality Evaluation Dataset of the Cold Lake Oil Sands Area Derived from 2007 Landsat Imagery' identifies misclassified pixels in Landsat data. Government of Alberta analysts produced this dataset to flag areas affected by sensor noise, cloud, haze, and cloud shadow. It was created to support the Lower Athabasca Regional Plan's science-based environmental monitoring objectives.

Use Cases

• Masking out 'bad pixels' (value '1') from 2007 Landsat composites for the Cold Lake area to improve land cover analysis.
• Validating automated land cover classification algorithms by comparing results against this quality evaluation layer.
• Assessing the impact of atmospheric conditions like cloud and haze on historical satellite imagery for environmental monitoring.

Strengths

• Covers a defined region: Township 56 to 69, Range 1 to 11, west of the 4th Meridian in Alberta.
• Provides a specific binary quality layer ('bad pixels' vs. good data) for a single year (2007).

Limitations

• Data is from a single year (2007), limiting temporal analysis and current applicability.
• The dataset's spatial resolution and specific pixel count are not provided in the description.
