OpenStreetMap US

Highway shields! Expressways! This talk introduces the OpenStreetMap “Americana” project, which aims to build an American map style, complete with the features that North American users expect to see on their maps.

We’ll explore the techniques involved in rendering highway shields and the challenges involved in rendering an attractive highway network given the quirks and complexities of the American highway system. On the implementation side, we’ll show how we’re implementing an American style on a vector-tile software stack using the OpenMapTiles schema, MapLibre, and ordinary Javascript. Lastly, we’ll highlight some of the future possibilities that a vector-based American map style can enable.
