摘要

Density maps show trends in objects' trajectories. Density map creation involves aggregating smoothed trajectories in a density field and visualizing the field. Using an interactive distribution map, users can define subsets and, supported by graphics hardware, get fast feedback for these computationally expensive density field calculations.
