Mapping LA by Night


Just Downtonw's LA Streetlights is an interactive map of street-lighting in Los Angeles. The map features dark extruded building footprints lit up by models of all the city's streetlights.

I don't think that the map was created for any other purpose than it looks really striking and provides an interesting map of the city at night. You can see, however, how the map could be useful to city planning departments, especially for reporting faults, scheduling repairs and maintaining the city's streetlights.

The map itself uses Mapbox GL's extrusion property both to show the city's buildings in 3d and for the streetlight models themselves. The data for the maps comes from Los Angeles GeoHub, the city's new public website for location-based open data.
