Calculate Population Density from Census Boundaries<\/h1>\n

Part 1<\/a> & Part 2<\/a> of this series explored how to prepare the first two inputs to a heat risk index (HRI). First, we derived high average summer temperature using the Multispectral Landsat<\/a> image service from ArcGIS Living Atlas of the World. Next, we calculated lack of tree canopy using the European Space Agency (ESA) WorldCover 2020 Land Cover<\/a> image service. For the final input, we will calculate population density using Living Atlas census polygons for the area of interest around Seville, Spain.<\/p>\n

This final blog will close out the series by walking through how to combine the three inputs into an HRI and mapping it to highlight areas that are hotter, have fewer trees to protect against extreme heat, and have more people. Local communities can use the resulting intervention-focused map as a planning tool to prioritize census tracts for tree planting as one mitigation against urban heat islands.<\/p>\n

The final input to the heat risk index is population density. You will, once again, use data from ArcGIS Living Atlas of the World to calculate this input using total population and polygon area.

Conclusion<\/h2>\n

This completes the third and final input to the HRI as well as the calculation and symbology of the map. After calculating the population density for each census section, you combined it with the other inputs. Next, you calculated the HRI using an Arcade expression and symbolized the polygons on a map. The map is now ready for sharing with stakeholders to prioritize census sections that would benefit most from tree planting as one mitigation of urban heat islands.<\/p>\n

I hope this blog series was helpful in explaining how disparate inputs can be standardized and combined to form a composite index. While this use case was for climate resilience planning, imagine all the other ways you could use this workflow for creating a composite index.
