Urban heat/freshness islands, temperature differences and urban heat island intensity index 2013-2014
The data presented on this page concern the 2013-2014 mapping of temperature differences, the classification maps of these temperature differences (i.e. urban heat and freshness islands) and the map of the urban heat island intensity index. These different maps are detailed below: The map of Temperature differences in °C represents the temperature difference in the city compared to a nearby forest. It was produced at the scale of the Quebec ecumene (2016 census, 167,764 km2). This mapping, provided on a grid with a spatial resolution of 15 m, was carried out with a predictive machine learning model built on Landsat-8 satellite data provided by the *United States Geological Survey (USGS) * as well as from other geospatial variables such as hydrography and topography. The mapping of surface temperature difference classes, i.e. __Urban Heat and Cool Islands (ICFU) __ was carried out for * [population centers of the 2021 census] (https://www150.statcan.gc.ca/n1/pub/92-195-x/2021001/geo/pop/pop-fra.htm) * (CTRPOP) with at least 1,000 inhabitants and a density of at least 400 inhabitants per km2 to which is added a buffer zone of 2 km. It thus covers all major urban centers, i.e.…
