Efficient Fetching of a Map Data During Animation |
摘要 |
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. |
