Provision of navigation service including reporting of elevation information and/or vertical guidance

Abstract

Methods, apparatuses and storage medium associated with navigation service are disclosed. In various embodiments, a method may include collecting, by a client mobile device, ambient barometric pressure information at a current location of the client mobile device. The method may further include providing, by the mobile device, contemporaneous navigation assistance to a user of the mobile device or for a user of the mobile device, assisted by a remote navigation assistance service. Assistance by the remote navigation service is associated with determining the current elevation level, based at least in part on ambient barometric pressure information collected by the client mobile device and by one or more crowdsourced mobile devices at the current location. Other embodiments may be disclosed or claimed.

1 . At least one computer-readable storage medium having instructions configured to enable a client mobile device, in response to execution of the instructions by the client mobile device, to:
 collect ambient barometric pressure information at a current location of the client mobile device; and   provide contemporaneous navigation service to a user of the client mobile device, or for the user of the client mobile device, assisted by a remote navigation assistance service, wherein provision of navigation service to the user includes provision of vertical navigation guidance to the user based at least in part on a determined current elevation level of the client mobile device, wherein provision of navigation service for the user includes reporting of the determined current elevation level, and wherein assistance by the remote navigation service is associated with determination of the current elevation level based at least in part on ambient barometric pressure information collected by the client mobile device and by one or more crowdsourced mobile devices at the current location.
