Sentinel-2 Satellite Mosaics for Quebec 2018-2020

Government and Municipalities of Québec provides three annual satellite mosaics covering the entire territory of Quebec. The mosaics contain multispectral imagery from the Copernicus Sentinel-2 mission for 2018, 2019, and 2020, featuring blue, near infrared, and short wave infrared spectral bands.

Use Cases

• Generate land use maps from the blue, near infrared, and short wave infrared spectral bands across Quebec.
• Detect land change by comparing annual mosaics from 2018, 2019, and 2020.
• Calculate geophysical variables like NDVI using the near infrared and blue band data.
• Analyze spatial patterns across the entire territory of Quebec using the 10-meter resolution imagery.

Strengths

• Covers the entire territory of Quebec for complete spatial analysis.
• Provides three consecutive years (2018, 2019, 2020) for temporal change detection.
• Includes three analytically distinct spectral bands: blue, near infrared, and short wave infrared.
• Data originates from the operational Copernicus Sentinel-2 satellite constellation.

Limitations

• Limited to only three years of data, restricting long-term trend analysis.
• Includes only three spectral bands, lacking the full multispectral suite available from Sentinel-2.
• Sample data and specific row/column counts are unavailable for preliminary assessment.
