Aspects of the present disclosure relate to generating turn-by-turn direction previews. In one aspect, one or more computing devices 110, 130, 140, 160, may receive a request for a turn-by-turn direction preview. The one or more computing devices may generate a set of turn-by-turn directions 332, 334 based on a series of road segments 1-4, 460, 462, 464, 466, 468 and 470 connecting a first geographic location A, 702 and a second geographic location B, 718. Each direction in the set of turn-by-turn directions may be associated with a corresponding waypoint 410, 420, 430, 440, 450. The one or more computing devices then identify a set of images PI, 502, 504, 506, 518, 520, 522, 602, 604, 606, 608, 610, 612, 614, 616, 618, 620, 622 corresponding the series of road segments between two adjacent waypoints of the set of turn-by-turn directions, and determine a subset of the set of images to include in the turn-by-turn direction preview. Subsequently, the one or more computing devices may generate the turn-by-turn direction preview based on at least in part on the determined subset of the set of images. |
