Montreal Agglomeration Climate Vulnerability Polygons

Polygons mapping areas vulnerable to heavy rains, heat waves, storms, droughts, and floods across the Montreal agglomeration. The data supports Montreal's Climate Plan 2020 2030 for urban planning and annual accountability reporting on 46 climate actions. It is updated as part of the city's climate adaptation strategy.

Use Cases

• Integrate vulnerability polygons into urban and mobility planning tools to identify high-risk zones for heat waves and floods.
• Analyze the spatial correlation between vulnerability to destructive storms and existing community infrastructure sensitivity.
• Track the evolution of climate hazards like droughts annually using the published vulnerability maps for accountability reports.
• Model system capacity to adapt by overlaying vulnerability polygons with demographic and land-use data layers.

Strengths

• Data is tied to Montreal's official Climate Plan 2020 2030 and its 46 specific climate actions.
• Includes multiple geospatial file formats (SHP, GPKG, GEOJSON) for compatibility with various GIS tools.
• Updated as part of a municipal commitment to revise climate change vulnerability analysis.

Limitations

• No quantitative sample data, row counts, or specific attribute columns are provided for analysis.
• The description is an automated translation, which may introduce inaccuracies in technical terminology.
• Spatial analysis is limited to the Montreal agglomeration, reducing broader geographic applicability.
