WebTrajectories. With GPS-enabled devices, it’s easy to collect a large quantity of trajectory data, i.e. a connected series of points in 2D or 3D. However, it’s not so easy to plot large datasets with most plotting programs, and so people generally downsample the trajectories, which can hide important features of the data.
