Global-scale data for population density. Current potential data sources include:
| Source | Nominal Resolution | Latest Data | Future Projections? |
|---|---|---|---|
| worldpop | 100m | 2015 | No |
| Euro. Commission Global Human Settlement | 250m | 2014 | No |
| Euro. Commission Joint Research Centre | 250m | 2015 | No |
| NASA Socioecon. Data (SEDAC) | 1km | 2020 | Yes |
Current analyses use worldpop only. Potential extension to incorporate
NASA data to allow for future projections.
This package currently contains only one function which maps the
population density layers in
who-data onto the nearest OSM
nodes, and dumps the resultant data in that repo (as
<city>/osm/popdens_nodes.Rds).
