Polygons representing heat islands on the ground surface. A heat island is defined as the difference in temperatures observed between two surrounding environments at the same time. The different temperature differences are mainly explained by the type of soil layout such as the vegetation cover, the impermeability of the materials and the thermal properties of the materials. This difference can reach more than 12°C.
The 2020-2030 Montreal Climate Plan aims, among other things, to improve urban planning and regulatory tools. Montréal has thus committed to updating the climate change vulnerability analysis, including the heat island map, carried out as part of the 2015-2020 Agglomération de Montréal Climate Change Adaptation Plan and to integrating it into the next urban and mobility plan. The urban heat island maps were produced in collaboration with the Department of Geography of the University of Quebec in Montreal (UQAM).
The data can also be viewed on the [interactive heat island map] (https://bter.maps.arcgis.com/apps/webappviewer/index.html?id=157cde446d8942d7b4367e2159942e05).This third party metadata element was translated using an automated translation tool (Amazon Translate).
