Abstract:
A mobile computing device can be used to locate a vehicle parking location. In particular, the mobile device can automatically identify when a vehicle in which the mobile device is located has entered into a parked state. The mobile device can determine that the vehicle is in a parked state by analyzing one or more parameters that indicate a parked state or a transit state. The location of the mobile device at a time corresponding to when the vehicle is identified as being parked can be associated with an identifier for the current parking location.
Abstract:
A mobile computing device can be used to locate a vehicle parking location in weak location signal scenarios (e.g., weak, unreliable, or unavailable GPS or other location technology). In particular, the mobile device can determine when a vehicle in which the mobile device is located has entered into a parked state. GPS or other primary location technology may be unavailable at the time the mobile device entered into a parked state (e.g., inside a parking structure). The location of the mobile device at a time corresponding to when the vehicle is identified as being parked can be determined using the first location technology as supplemented with sensor data of the mobile device. After the location of the mobile device at a time corresponding to when the vehicle is identified as being parked is determined, the determined location can be associated with an identifier for the current parking location.
Abstract:
Methods, computer-readable media, and computer systems for finding wireless network access points. Geographic location information describing a geographic location of a computer system within a geographic area is received. From a storage medium that stores information defining multiple geographic cells and, for each cell, information defining multiple wireless network access points, a particular geographic cell within which the geographic location described by the geographic location information is located is identified. Access points within the particular geographic cell are identified, and provided in response to receiving the geographic location information.
Abstract:
Some embodiments provide a navigation application that presents a novel navigation presentation on a device. The application identifies a location of the device, and identifies a style of road signs associated with the identified location of the device. The application then generates navigation instructions in form of road signs that match the identified style. To generate the road sign, the application in some embodiments identifies a road sign template image for the identified style, and generates the road sign by compositing the identified road sign template with at least one of text instruction and graphical instruction. In some embodiments, the road sign is generated as a composite textured image that has a texture and a look associated with the road signs at the identified location.
Abstract:
Methods, systems, and computer-readable media for a location information server to gather location updates by sending location-update-requests through a push notification service to a mobile device are disclosed. The mobile device provides location updates in response to the push-based location-update-requests received through the push notification service. The mobile device can switch from a self-initiated location update mode to a push-based location update mode depending on the current state of the mobile device. The mobile device can also choose an appropriate positioning system for self-locating based on the information embedded in the location-update-request received through the push notification service.; The information embedded in the pushed location-update-request can be a precision requirement or context information that can be used to determine a precision requirement for the location update.
