Abstract: Disclosed are devices, methods and storage media for use in determining position information for imaging devices or mobile devices. In some implementations, a landmark is identified in an image which is obtained from an imaging device which in turn is positioned at a location and in a pose. A virtual two-dimensional image that would be visible from the landmark is determined based, at least in part, on the pose. The location or position information is based, at least in part, on the virtual two-dimensional image.

Abstract: An embodiment is directed to generating a polygon representation of a plurality of points of interest (POIs) in a scene having a corresponding base level map of the scene, and creating a new level map including a reduced number of polygon representations of POIs on the basis of elimination of POIs having a lower than specified POI importance level. In another embodiment, a mobile device (e.g., the user device) can specify the specified POI importance level to trigger the generation and delivery of the new level map which conforms to the specified POI importance level so that the new level map can be displayed to a user of the mobile device (e.g., in conjunction with navigation instructions to one or more of the remaining POIs).
