    Abstract: In some implementations, a system can optimize offline map data updates. For example, a server device in the system can determine a metric for identifying map data objects based on attributes of the map data objects. The server device can then generate a quadtree that stores the map data objects in nodes of the quadtree based on the metric. When processing an update to the map data stored at the server device, the server device can generate update data describing the updates for each node in the quadtree based on a binary difference algorithm and/or a semantic difference algorithm. The server device can select the algorithm based on which algorithm results in the smallest compressed size of the update data.

    Abstract: A method of providing travel updates for an event stored in a calendar application of a device is provided. The method receives the location and the starting time of the event from the calendar application at a navigation application of the device. The method determines an estimated travel time from the current location of the device to the location of the event. The method determines a time for timely departure to the event based on the estimated travel time. The method provides several travel updates that include the time for timely departure to the calendar application. The travel updates are utilized by the calendar application to provide a set of alerts regarding the time for the timely departure to the event.

    Abstract: A method of determining a location of an event stored on a calendar application of a device is provided. The method sends a location string associated with the event from the calendar application to a geo coder. The method receives a handle that includes a set of data items that uniquely identifies the location of the event. The data items in the handle are not accessed or individually utilized by the calendar application. Prior to the start of the event, the method requests travel updates to the location of event from a navigation application. The request includes the handle and the start time of the event. The method receives periodic routing updates to the location of the event from the navigation application.

    Abstract: In some implementations, a computing device can identify relevant locations using location data gathered by and/or entered into the device. In some implementations, the device can proactively request offline map data for the relevant locations. A server can identify offline map data responsive to the request and send at least a portion thereof to the device in response. In some implementations, the device can suggest downloading offline map data for the relevant locations to a user before requesting the data. The user may be able to edit the location and/or search for other locations to download. The device may provide features for managing downloaded offline map content automatically and/or in response to user input.
