Abstract: A computer-implemented method includes generating a user interface for displaying one or more images, receiving a request from a remote device to view the user interface, determining whether the remote device is a mobile device communicating over a wireless network, depending on a result of the determination, generating a low resolution version of the user interface that is computationally less intensive to render compared to the previously generated user interface, and transmitting the low resolution version of the user interface to the requesting device.

Abstract: Methods, program products, and systems for managing a location database are described. A server computer can receive location information from location-aware mobile devices (e.g., GPS-enabled devices) located within a communication range of access points of a wireless communications network. The server computer can calculate average geographic locations using the received locations for each access point. Based on the average geographic locations, the server computer can assign the access points to cells of a geographic grid. The server computer can filter the access points in each cell based on popularity, stability, longevity, and freshness of the access point and the received data. When a second mobile device connects to an access point in a cell, the server computer can transmit locations of the access points in the cell and in neighboring cells to the second mobile device such that a location of the second mobile device can be estimated.

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.

Abstract: On a mobile device a “live” network-based query for search is performed (e.g., performed automatically) in response to a map display update or other trigger event. In some implementations, when the map display is updated (or other trigger event occurs) a network-based map service is queried to obtain information related to the current location of the mobile device. The information can be presented on the map display. In some implementations, when multiple search results matching the query are provided by the map service, a confirmation request is presented on the mobile device to allow the user to select a search result. The selected search result (e.g., a destination) can be presented on the map display. A route from the current location of the mobile device to a destination can be drawn on the map display.

Abstract: A client publishes rich media content by receiving a message including a representation of imagery content. A publishing control is presented, in association with the message, that enables the user to transmit the imagery content to a publishing host. The user is enabled to interact with the publishing control and the representation of the imagery content to publish the imagery content using the publishing host.

Abstract: A computer-implemented method includes receiving from a mobile device communicating over a wireless network a request for a content item, generating an identifier to represent a network location at which the content item is stored, and transmitting the identifier and the content item to the mobile device, wherein the mobile device is configured to perform operations including display the item in a first frame in a user interface on the mobile device, display the identifier in a second frame in the user interface, and enable a user to perform manipulations on the content item.
