Abstract: A request for navigation directions for travelling from a source location to a destination location is received. Using data that was stored in a memory of a computing device prior to the request, first navigation directions for travelling from the source location to the destination location are generated, and a request for navigation directions for travelling from the source location to the destination location is transmitted to an online server. After second navigation directions for travelling from the source to the destination are received, it is determined whether a difference between the first navigation directions and the second navigation directions exceeds a threshold level. When the difference between the first navigation directions and the second directions route does not exceed the threshold level, the second navigation directions are merged into the first navigation directions.

Abstract translation: 接收从源位置到目的地位置的导航指示的请求。 使用在请求之前存储在计算设备的存储器中的数据，产生从源位置到目的地位置的第一导航方向，并且从源位置到目的地位置的用于行进的导航方向的请求是 传输到在线服务器。 在从源到目的地的第二导航方向被接收之后，确定第一导航方向和第二导航方向之间的差是否超过阈值水平。 当第一导航方向和第二方向路线之间的差异不超过阈值水平时，第二导航方向被合并到第一导航方向。
