Mapping Anomalies: A New Vision for Long-Term Trajectory Analysis
![TITAnD encodes the chaotic whispers of movement - whether dense GPS streams or sparse stay-points - into a unified hyperspectral trajectory image, where each pixel doesn’t simply mark location, but embodies a confluence of space, semantics, time, and the subtle poetry of motion [latex] day × time [/latex].](https://arxiv.org/html/2603.25255v1/imgs/intro-v5.png)
Researchers have developed a novel method for detecting unusual patterns in months-long GPS data by transforming movement into visual representations.
