    • A system and method are disclosed for displaying map information on a computing device. Data are stored for rendering a simulation of travel along one or more road segments prior to embarking on travel along the road segments. The simulation is comprised of a sequence of views of the road network along each road segment from vantage points above or along the road network. Each road segment may be part of a calculated route and the simulation may include views for all the road segments contained in the calculated route. While the computing device is being conveyed along each road segment, the data stored for the simulation is used to show a view of the road network that includes the current position of the computing device on a display of the computing device.
    • 公开了一种用于在计算设备上显示地图信息的系统和方法。 存储数据用于在沿着路段行驶之前沿着一个或多个路段进行旅行的模拟。 该模拟由沿着道路网络上方或沿着道路网络的有利位置的沿着每条路段的道路网络的视图序列组成。 每个路段可以是计算的路线的一部分,并且模拟可以包括包含在所计算的路线中的所有道路段的视图。 当沿着每个路段传送计算设备时,为模拟而存储的数据用于显示包括计算设备在计算设备的显示器上的当前位置的道路网络的视图。
