The Cold Lake oil sands area - Township 56 to 69, Range 1 to 11, west of the 4th Meridian, falls within the Lower Athabasca Regional Plan (LARP). As part of Alberta's Land-use Framework, LARP was developed in 2012 to set the stage for robust growth, vibrant communities and a healthy environment within the region. One of its implementation objectives is to balance the economic development of oil sands and impacts on the ecosystem and environment. This is to be achieved through an enhanced science-based monitoring for improved characterization of the environment and to collect the information necessary to understand cumulative effects. This quality evaluation dataset was produced for 2011 Landsat data to identify possible misclassified areas due to sensor noise, cloud, haze, and cloud shadow. These areas are assigned to 'bad pixels' or value '1' in the quality evaluation dataset.
