Abstract: A position fix identifying a geographic location of a receiver is received. The position fix was generated using signals received at the receiver from respective high-altitude signal sources (such as satellites). Imagery of a geographic area that includes the geographic location is also received. The imagery is automatically processed to determine whether one or more of the high-altitude signal sources were occluded from the geographic location when the position fix was generated. In response to determining that one or more of the high-altitude signal sources were occluded from the geographic location when the position fix was generated, the position fix is identified as being potentially erroneous.

Abstract: Methods and apparatus to select and present level-change way points for indoor navigation systems are disclosed. An example method includes: receiving, from a client device having a navigation system interface, a request for navigation directions from a starting point to a destination point; identifying, by one or more processors, a plurality of level-change way points based on a starting level associated with the starting point; determining, by one or more processors, a subset of two or more of the plurality of level-change way points based on a destination level associated with the destination point; selecting, by one or more processors, a selected level-change way point from the subset based upon one or more criteria; and providing, to the client device, directions to present an indication of a location of the selected level-change way point in the navigation system user interface.

Abstract: Methods and systems for presenting imagery associated with a geographic location to a user include providing at least one geographic map or panoramic imagery to a client for display in an interface configured for interactive navigation of the at least one geographic map or panoramic imagery, receiving a user selection collected by the interface indicating a location corresponding to the at least one geographic map or panoramic imagery, identifying a plurality of images associated with the received user selection, obtaining at least one user preference associated with the identified images, ranking the identified images based on at least one of the retrieved user preferences, and providing at least one ranked image for display in the interface, in accordance with the ranking.

Abstract: Systems and methods are disclosed for transferring information metadata from a first digital image to a second digital image. In one embodiment, an assignment module is configured to assign a corresponding portion of the first image to the second image using geolocation data. An extraction module is configured to extract a collection of features associated with the second image and the corresponding portion of the first image. An alignment module is configured to align the second image with a portion of the first image by transforming the second image so that features associated with the second image are geometrically aligned with the corresponding features of the portion of the first image. A metadata module is configured to associate metadata from the portion of the first image with the transformed second image. An annotation module is configured to annotate the second image with the associated metadata to generate an annotated image.

Abstract: Methods, systems, and articles of manufacture for presenting similar images are disclosed. A method for presenting similar images on a display device is disclosed. The method includes displaying a first image on the display device; determining one or more homographic relationships between the first image and a plurality of images; identifying, using the determined one or more homographic relationships, at least one image having a scene and a perspective which are similar to that of the first image; and displaying the identified image. Corresponding system and computer readable media embodiments are also disclosed.

Abstract: Methods, systems, and computer program products for transitioning an interface to a related image are provided. A method for transitioning an interface to a related image may include receiving information describing a homography between a first image and a second image, and adjusting the interface to present the second image at one or more transition intervals in a transition period until the second image is fully displayed and the first image is no longer visible. The interface may be adjusted by determining, based on the homography, a region of the second image to overlay onto a corresponding area of the first image, blending the determined region with the corresponding area to reduce visible seams occurring between the first image and the second image, and updating the interface by gradually decreasing visual intensity of the first image while gradually and proportionally increasing visual intensity of the second image.
