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.
