Abstract
An interactive digital map of a geographic area is provided via a user interface of a user device, with the currently visible portion of the interactive digital map visible within a viewport. The viewport is repositioned from an initial position on the digital map to a target position on the digital map along a trajectory in accordance with one or more user commands. For different positions on the trajectory of the viewport, navigation directions to a geographic location near a center of the viewport are automatically retrieved, without receiving commands via the user interface to obtain navigation directions to the geographic location. The navigation directions having a first and second levels of detail are retrieved for a first and second points on the trajectory, respectively, the first level of detail including less information than the second level of detail. The navigation directions are displayed via the user interface.
