AI Technical Summary
Existing trajectory heatmap generation methods struggle to retain trajectory direction information while maintaining high efficiency when processing trajectory data containing directional attributes. Furthermore, existing methods are prone to feature loss when multiple trajectories in different directions are superimposed.
The server generates trajectory feature tile data, which includes multi-dimensional trajectory features such as trajectory intensity and vector-based direction information. The data is then aggregated on the server to generate aggregated feature data, which is returned to the client for rendering. This supports flexible display and interactive exploration of multi-dimensional trajectory features.
It enables rapid response and accurate display of trajectory flow and density under high concurrency and large-scale visualization requests, enhancing the information expression capability of heatmaps and improving the visualization accuracy and practicality of trajectory data.
