Mapbox map projections

Mapbox supports the popular Web Mercator projection, and currently does not support any other projections as output. Web Mercator is a nearly conformal projection that is adopted by the vast majority of web maps and its use allows you to combine Mapbox’s maps with other layers in the same projection.

Commonly this projection is referred to as EPSG:900913 or EPSG:3857: see for more information and alternative encodings.
