First there were DJs, then there were VJs. Clear the booth and make room for the MJ (map jockey).

Carto-OSC leverages a handful of open source libraries, data, and protocols in order to activate performance spaces – theaters, galleries, nightclubs – with projected, real time cartography. The Open Sound Control (OSC) protocol, itself a mature successor to MIDI (Musical Instrument Digital Interface), is coupled with a touch surface to control layer coloring and patterning, zoom/pitch/bearing effects, label typography, transits along road networks and great circles, and a variety of transitions purloined from the history of cinema and visual music.

Carto-OSC is written in modern JavaScript and relies on the solid foundation of Open Stage Control, MapLibre, D3.js, chroma.js, as well as OpenStreetMap and Natural Earth data.

This presentation describes the architecture of Carto-OSC, the impulses behind its creation, development, and future, and includes documentation of its use in performances of music, dance, and spoken word.
