Great Britain developers Parallel convey released an interactive map which visualizes Great Britain population density inwards 3D. Their ONS Population Estimates map shows the population density inwards each Great Britain Lower Super Output Area (LSOA) in addition to the historic menstruum breakdown of the population inwards each LSOA.
The population density sentiment on the map uses Mapbox GL's extrusion belongings to exercise 3D towers on the map. The pinnacle of the towers represents the population density of the LSOA. In other words the higher the tower in addition to thence the greater the population density.
If yous switch to the 'Age Profile' pick in addition to thence yous tin sentiment a breakdown of the numbers inwards each historic menstruum grouping of both the manful mortal & woman mortal population inwards each LSOA. In this 'Age Profile' agency the map withal shows a choropleth sentiment of the population density. However if yous hover over an LSOA on the map in addition to thence yous tin sentiment a population pyramid nautical chart which visualizes the area's historic menstruum profile.
Mapbox has besides used the extrusion belongings to visualize population density. Their Population Density Inspector allows yous to sentiment the seat out of people living inwards each census block inwards America equally a 3D tower.
On The Population Density Inspector the pinnacle of each census block on the map represents the population density (based on census block population counts). You tin read close how Mapbox created their map (with a picayune tending from Turf.js in addition to Tippecanoe) on the Mapbox blog.
You don't convey to move Mapbox GL's extrusion belongings to map population density inwards 3D. Bjørn Sandvik has posted an interesting tutorial on how to move Three.js & D3.js to visualize population density inwards 3D. The tutorial includes a 3D map of Oslo's population density
The minute tutorial inwards Mapping Grid-Based statistics using OpenLayers, Three.js in addition to D3.js provides a 3d visualization of Oslo's population data, alongside each grid's population density shown equally a 3D tower or block on the map. The tutorials inwards the post service are inwards Norwegian simply the source code is available on GithHub in addition to should live on slow to follow for anyone familiar alongside OpenLayers in addition to D3.js.
