Montreal Urban Heat Island Polygons for Climate Planning

Polygons represent urban heat islands, defined by temperature differences up to 12°C. The data supports Montreal's 2020-2030 Climate Plan and updates vulnerability analyses from 2015-2020. It was produced in collaboration with the University of Quebec in Montreal's Department of Geography.

Use Cases

• Analyze heat island polygon shapes and temperature differentials to model urban microclimates.
• Integrate polygon data with urban planning tools to assess vulnerability and guide regulatory updates.
• Use the polygon-based heat island map to evaluate the impact of vegetation cover and material impermeability on surface temperatures.
• Correlate heat island intensity with land use data for climate adaptation strategies within the Montreal agglomeration.

Strengths

• Polygons represent concrete temperature differentials that can exceed 12°C.
• Data is integrated into Montreal's official 2020-2030 Climate Plan for actionable policy.
• Produced in collaboration with an academic geography department (UQAM) for methodological rigor.
• Available in multiple geospatial formats (GEOTIF, GEOJSON, SHP) for interoperability.

Limitations

• Specific row count, column attributes, and spatial resolution are not provided in the metadata.
• The dataset's temporal coverage and update frequency for the polygon analysis are unclear.
• Relies on an automated translation for parts of its description, which may obscure technical details.
