Abstract
Some embodiments provide a method for a mapping service. The method receives a set of road segments for a map region. For each road segment in the set, the method generates a geometry that includes a set of vertices that define a boundary for the road segment. The geometries are included as part of a map tile for the map region. The map tiles are for downloading to user devices that render map presentations using the geometries. For several of the vertices, the method stores data with the vertices that specifies for the device at least one aspect of rendering the road for the map presentation.
