Quebec Spring 2020 Flood Monitoring with Satellite Imagery

Flood monitoring data for Quebec in Spring 2020 includes Sentinel-1 and Sentinel-2 satellite imagery, flood event locations, and affected municipalities. The collection features processed radar and optical imagery with 10-meter resolution for specific river sectors. Data was provided by Dromedaire Géo-Innovations and the European Space Agency.

Use Cases

• Identify flooded areas by analyzing Sentinel-1 radar images from April 4 and March 23, 2020 for comparative change detection.
• Map open water extent using Sentinel-1 derived limits to monitor flood progression in near real-time.
• Correlate flood event locations with affected municipality boundaries to assess regional impact.
• Analyze visible and near-infrared Sentinel-2 imagery from April 8, 2020 for land cover classification in the Lac Saint-Pierre sector.

Strengths

• Includes multiple data types: event locations, municipality boundaries, and processed satellite imagery.
• Sentinel-1 radar imagery provides 10-meter resolution data for flood and ice cover mapping.
• Data is updated in real-time for municipality flood status according to the description.
• Covers a specific, significant flood event period starting April 2, 2020.

Limitations

• Sample size, row count, and total data volume are unknown.
• Primary satellite coverage is limited to specific sectors like the Chaudière River and Lac Saint-Pierre.
• Relies on automated translation for metadata, which may introduce inaccuracies.
