    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: 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.
