Elevation Music is an interactive map in which the elevation data is styled based on the intensity of an accompanying music track. It is a dancing map!
If you want to know how Elevation Music works the author's blog post explains:
'This demo uses Mapbox GL JS raster-color-value and other raster-* paint properties to alter the colors on the map by elevation, based on the intensity of the music. Turn sound on and click the play button to start the experience.'
The blog post also reveals that the song used by the map is actually called 'Elevation'.
Inside every cartographer, there’s a musician trying to get out - or at least it seems that way, judging by the number of musical maps.
Take, for example, the ever-popular Ohio is a Piano. Andy Woodruff’s map turns Ohio’s 88 counties into the 88 keys of a piano, meaning you can literally play the map like an instrument. You can even listen to it perform a version of Scott Joplin’s The Entertainer.
Transit maps can be instruments too. For example MTA.me Conductor transforms Massimo Vignelli’s 1972 New York subway map into a real-time string instrument. It visualizes subway trains moving across the network - and plays a note every time one train crosses paths with another.
Fire up the map and just sit back as a New York subway symphony is composed and performed in real time. You can even join the composition by plucking the trails created by individual trains.
Mapbox's Animate 3D buildings based on ambient sounds is another dancing map - but this time, it’s the buildings that groove. Instead of elevation data being influenced by music, this map makes 3D buildings respond to sound.
According to Mapbox:
"It uses runtime styling with the Web Audio API to create a map where the 3D buildings dynamically change height to the rhythm of your ambient environment, giving the appearance of dancing."
In layman’s terms? The buildings on this map will dance when you sing to them!
