1. A computer-implemented method for identifying prominent landmarks in a geographic area, the method comprising: accessing, by the one or more computing devices, geographic imagery data captured from one or more cameras from a perspective at or near ground level; generating, by the one or more computing devices, a point cloud based at least in part on the geographic imagery data, the point cloud comprising a plurality of data points, each of the plurality of data points associated with a tracked feature in the geographic imagery data; identifying, by the one or more computing devices, a subset of data points in the point cloud, each data point in the subset located at least a threshold distance away from one or more camera perspectives associated with the geographic imagery data; and matching, by the one or more computing devices, one or more data points in the subset of data points with a landmark; determining, by the one or more computing devices, a landmark ranking for the landmark based at least in part on the one or more data points; and providing, by the one or more computing devices, travel directions in response to a request for travel directions, wherein the travel directions comprise data indicative of one or more landmarks identified based at least in part on the landmark ranking.
