Abstract: A first digital map is displayed in a viewport at an initial position. When a user gesture that communicates motion to the viewport is detected, a trajectory of the viewport from the initial position to a target position is determined based on kinematic quantities of the communicated motion. Map data for displaying a second digital map in the viewport at the target position is retrieved from a first memory, prior to the viewport reaching the target position. The retrieved map data is stored in a second memory having a higher speed of access than the first memory. The second memory is retrieved for display via the user interface when the viewport is at the target position.
Abstract translation: 在初始位置的视口中显示第一个数字地图。 当检测到向视口通信运动的用户手势时,基于所传送的运动的运动量确定从初始位置到目标位置的视口的轨迹。 在视口到达目标位置之前,从第一存储器检索用于在目标位置的视口中显示第二数字地图的地图数据。 检索到的地图数据被存储在具有比第一存储器更高的访问速度的第二存储器中。 当视口处于目标位置时,通过用户界面检索第二个内存以供显示。
