We've brought the Emerald basemap to GL. Some highlights:
Interactive map
Deep road hierarchy
Not all streets are created equal. From bustling motorways to the narrowest alleys and backroads, Emerald boasts 8 road classes for a great sense of depth at any zoom level.
Mapbox terrain
We compiled data from 20 different sources to create dramatic hillshades around the world.
Public transit
Emerald puts emphasis on subway and light rail stations, giving a macro view of transit coverage in every city. Select locations also have custom insignias.
As with Streets style, Emerald will be available in the upcoming launch of GL for iOS. Stay tuned!
