Claim One:
1. A method of rendering geometric shapes adjacent to corresponding roads within a geographic map, the method comprising: determining one or more map tiles on which a geometric shape will be rendered, the geometric shape associated with a road having a corresponding road segment geometry, each map tile comprising graphical data of a corresponding geographical region at a specific zoom level; determining, for each map tile on which the geometric shape will be rendered, whether the corresponding road segment geometry is available in the map tile; and rendering each of the one or more map tiles with the geometric shape according to the determination of whether the corresponding road segment geometry is available including: for each map tile for which the corresponding road segment geometry is available, rendering the map tile with the geometric shape includes using (1) a first vector that is inside of a polyline of the road segment geometry, (2) a second vector, perpendicular to the first vector, that indicates the side of the road on which the geometric shape will be rendered, and (3) a value corresponding to the actual width of the road segment geometry, and for each map tile for which the corresponding road segment geometry is not available, rendering the map tile with the geometric shape includes using (1) a first vector that is inside of a polyline of the road segment geometry, (2) a second vector, perpendicular to the first vector, that indicates the side of the road on which the geometric shape will be rendered, and (3) a value corresponding to a default width of the road segment geometry.
