Landsat Top of Atmosphere Reflectance Mosaic of Canada, Circa 2010

Canada's land surface is represented in this 30-meter resolution mosaic derived from Landsat TM and ETM+ sensors. Natural Resources Canada processed data from 2009-2011, with a preference for 2010, applying cloud detection, reflectance conversion, and scan-line correction. The product includes four spectral bands optimized for land cover and biophysical mapping applications.

Use Cases

• Land cover classification based on 30-meter resolution multispectral reflectance data.
• Biophysical parameter mapping (e.g., vegetation indices) using the provided near-infrared and shortwave infrared bands.
• Environmental change detection and baseline studies leveraging the circa 2010 temporal composite.
• Training and validating machine learning models for satellite image analysis on a national scale.

Strengths

• Processed to Standard Terrain Correction Level 1T by the USGS, indicating a high standard of geometric correction.
• Includes specific corrections for the Landsat 7 scan line malfunction using a Fourier transformation approach.
• Multi-criteria compositing was used to select the most representative pixel from data across 2009-2011.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The product excludes blue and green spectral bands due to significant atmospheric effects limiting their quality.
