Abstract:
Some embodiments provide a non-transitory machine-readable medium that stores a mapping application which when executed on a device by at least one processing unit renders views of a three-dimensional (3D) map. The mapping application requests a first set of map tiles associated with a portion of the 3D map. In response to the request, the mapping application receives a second set of map tiles associated with portion of the 3D map. The mapping application identifies a third set of map tiles included in the first set of map tiles but not included in the second set of map tiles. For each map tile in the third set of map tiles, the mapping application generates a replacement map tile comprising geospatial data. The mapping application renders the portion of the 3D map based on the second set of map tiles and the set of replacement map tiles.
Abstract:
Methods, systems and apparatus are described to provide visual feedback of a change in map view. Various embodiments may display a map view of a map in a two-dimensional map view mode. Embodiments may obtain input indicating a change to a three-dimensional map view mode. Input may be obtained through the utilization of touch, auditory, or other well-known input technologies. Some embodiments may allow the input to request a specific display position to display. In response to the input indicating a change to a three-dimensional map view mode, embodiments may then display an animation that moves a virtual camera for the map display to different virtual camera positions to illustrate that the map view mode is changed to a three-dimensional map view mode.
Abstract:
Some embodiments provide a mapping application for generating views of a three-dimensional (3D) map. The mapping application includes a geographic data module for identifying a set of geographic data that represents a portion of the 3D map. The set of geographic data includes a set of camera captured images that correspond to the portion of the 3D map. The mapping application includes an image processing module for rendering the view of the 3D map based on the geographic data by animating a type of map element in the view of the 3D map.
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:
Techniques for performing context-sensitive actions in response to touch input are provided. A user interface of an application can be displayed. Touch input can be received in a region of the displayed user interface, and a context can be determined. A first action may be performed if the context is a first context and a second action may instead be performed if the context is a second context different from the first context. In some embodiments, an action may be performed if the context is a first context and the touch input is a first touch input, and may also be performed if the context is a second context and the touch input is a second touch input.
Abstract:
A multitouch device can interpret and disambiguate different gestures related to manipulating a displayed image of a 3D object, scene, or region. Examples of manipulations include pan, zoom, rotation, and tilt. The device can define a number of manipulation modes, including one or more single-control modes such as a pan mode, a zoom mode, a rotate mode, and/or a tilt mode. The manipulation modes can also include one or more multi-control modes, such as a pan/zoom/rotate mode that allows multiple parameters to be modified simultaneously.

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:
A compass output in a first portable electronic device is monitored as the first device and a second electronic device come closer to each other. It is determined, by a process running in the first device, whether a magnetic field signature that is based on the monitored compass output is associated with a previously defined type of electronic device with which a network device discovery process is to be conducted. Other embodiments are also described and claimed.
