Land Cover Quality Evaluation for Alberta Energy Regulation Pilot

A quality evaluation dataset identifies misclassified pixels in 2007 Landsat imagery covering a specific energy regulation pilot area in Alberta. It was produced by the Alberta Energy Regulator to assess surface change from energy exploration. The data flags areas affected by sensor noise, cloud, haze, and cloud shadow.

Use Cases

• Filtering out 'bad pixels' (value '1') from 2007 Landsat classifications to improve land cover map accuracy for the pilot region.
• Training a model to detect cloud, haze, and sensor noise artifacts in satellite imagery using the provided quality flags.
• Benchmarking automated quality assessment algorithms against this human-annotated evaluation layer for geospatial data.
• Analyzing the spatial distribution of classification errors relative to towns like Edson and Whitecourt within the pilot area.

Strengths

• Focuses on a defined pilot area spanning from Township 52 to 70 in Alberta.
• Specifically targets known classification error sources: sensor noise, cloud, haze, and shadow.

Limitations

• Covers only a single year (2007), limiting temporal trend analysis.
• Unknown sample size and spatial resolution details for the quality evaluation layer.
• Potential geographic bias, being confined to a specific energy regulation pilot zone in Alberta.
