    Abstract: Methods and systems are provided for efficiently identifying map tiles of a raised-relief map to retrieve from a server. An electronic device can use estimates of height(s) for various region(s) of the map to determine map tiles that are likely viewable from a given position of a virtual camera. The device can calculate the intersection of the field of view of the virtual camera with the estimated heights to determine a location of the map tiles (e.g., as determined by a 2D grid) needed. In this manner, the electronic device can retrieve, from a map server, the map tiles needed to display the image, without retrieving extraneous tiles that are not needed. Identifying such tiles can reduce the amount of data to be sent across a network and reduce the number of requests for tiles, since the correct tiles can be obtained with the first request.

    Abstract: Some embodiments provide a mapping application that has a novel way of displaying traffic congestion along roads in the map. The mapping application in some embodiments defines a traffic congestion representation to run parallel to its corresponding road portion when the map is viewed at a particular zoom level, and defines a traffic congestion representation to be placed over its corresponding mad portion when the map is viewed at another zoom level. The mapping application in some embodiments differentiates the appearance of the traffic congestion representation that signifies heavy traffic congestion from the appearance of the traffic congestion representation that signifies moderate traffic congestion. In some of these embodiments, the mapping application does not generate a traffic congestion representation for areas along a road that are not congested.
