[edit] About the hack

An entirely client-side Javascript application which pulls data from OpenStreetMap and then generates audio tones on the client using the HTML5 Audio API to convert the feature information into sound. There's a small NodeJS server included which simply proxies the AJAX requests to get around cross-origin security.

[edit] Demos

• Parking Lots, Toilets and Brothels, oh my!

[edit] What APIs, tools, kits or other amenities did you use?

• Google Maps
• OpenStreetMap for the feature information
• Audiolet for HTML5 audio generation
• Stamen Maps for custom mapping tiles
