I guess one reason why I haven’t done heat maps before is because I don’t think they are as useful compared to other cartographic #dataviz techniques such as binning and choropleths. But maybe I’m missing something?

Anyway, for the heat map, I used the Leaflet.heat #LeafletJS plugin by Volodymyr Agafonkin, creator of Leaflet: github.com/Leaflet/Leaflet.hea

The hexbin map uses the #H3 hex grid system with the #Viridis Inferno sequential palette.

The Bing ML buildings data is from this GitHub repo and first released in 2012: github.com/microsoft/IdMyPhBui

I used the following tools/services:
▪︎ @geofabrik for the OSM buildings
▪︎ #OverpassTurbo for extracting clipping polygons from OSM
▪︎ Osmosis for filtering the OSM buildings
▪︎ @qgis #QGIS for GeoJSON clipping and data conversion
▪︎ A couple of hand-coded Perl scripts for data manipulation
▪︎ #TurfJS
▪︎ #LeafletJS for rendering
▪︎ H3 for hexbinning
▪︎ @GIMP #GIMP for final map prep
