Urban Heat Island Interactive Map (IMAGE) Portland State University Caption An interactive map of Portland showing temperature differences under two scenarios: a largely paved environment, which makes for hotter temperatures, and one in which cooling solutions, such as planting more vegetation and using reflective materials on roofs and pavement, are employed. Users can move the map's vertical bar left or right to see differences in specific neighborhoods under the two scenarios.
