The Argoverse 2 Map Change Dataset is a collection of 1,000 scenarios with ring camera imagery, lidar, and HD maps. Two hundred of the scenarios include changes in the real-world environment that are not yet reflected in the HD map, such as new crosswalks or repainted lanes. By sharing a map dataset that labels the instances in which there are discrepancies with sensor data, we encourage the development of novel methods for detecting out-of-date map regions.

The Map Change Dataset does not include 3D object annotations (which is a point of differentiation from the Argoverse 2 Sensor Dataset). Instead, it includes temporal annotations that indicate whether there is a map change within 30 meters of the autonomous vehicle at a particular timestamp. Additionally, the scenarios tend to be longer than the scenarios in the Sensor Dataset. To avoid making the dataset excessively large, the bitrate of the imagery is reduced.
