Abstract: Methods, systems and apparatus are described to dynamically generate map textures. A client device may obtain map data, which may include one or more shapes described by vector graphics data. Along with the one or more shapes, embodiments may include texture indicators linked to the one or more shapes. Embodiments may render the map data. For one or more shapes, a texture definition may be obtained. Based on the texture definition, a client device may dynamically generate a texture for the shape. The texture may then be applied to the shape to render a current fill portion of the shape. In some embodiments the render map view is displayed.

Abstract: Some embodiments of the invention provide a navigation application that allows a user to peek ahead or behind during a turn-by-turn navigation presentation that the application provides while tracking a device (e.g., a mobile device, a vehicle, etc.) traversal of a physical route. As the device traverses along the physical route, the navigation application generates a navigation presentation that shows a representation of the device on a map traversing along a virtual route that represents the physical route on the map. While providing the navigation presentation, the navigation application can receive user input to look ahead or behind along the virtual route. Based on the user input, the navigation application moves the navigation presentation to show locations on the virtual route that are ahead or behind the displayed current location of the device on the virtual route. This movement can cause the device representation to no longer be visible in the navigation presentation. Also, the virtual route often includes several turns, and the peek ahead or behind movement of the navigation presentation passes the presentation through one or more of these turns. In some embodiments, the map can be defined presented as a two-dimensional (2D) or a three-dimensional (3D) scene.

Abstract: A device that provides a map and/or navigation application that displays items on the map and/or navigation instructions differently in different modes. The applications of some embodiments provide a day mode and a night mode. In some embodiments the application uses the day mode as a default and activates the night mode when the time is after sunset at the location of the device. Some embodiments activate night mode when multiple conditions are satisfied (for example, when (1) the time is after sunset at the location of the device and (2) the ambient light level is below a threshold brightness).

Abstract: Some embodiments of the map display application described herein display three-dimensional representations of three-dimensional objects. When the map presentation is moved to display a new area, the three-dimensional representations rise from a ground level to their full heights and transition from transparent to opaque at the same time. The map display applications of some embodiments also remove three-dimensional representations of objects by lowering the objects from their full height to ground level and fading out the representations from opaque to transparent.

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.
