摘要

A multi-step animation sequence for smoothly transitioning from a map view to a panorama view of a specified location is disclosed. An orientation overlay can be displayed on the panorama, showing a direction and angular extent of the field of view of the panorama. An initial specified location and a current location of the panorama can also be displayed on the orientation overlay. A navigable placeholder panorama to be displayed in place of a panorama at the specified location when panorama data is not available is disclosed. A perspective view of a street name annotation can be laid on the surface of a street in the panorama.
