{"url":"/dataset/argoverse-2-map-change","name":"Argoverse 2 Map Change","full_name":null,"description_markdown":"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in which there are discrepancies with sensor data, we encourage the development of novel methods for detecting out-of-date map regions.\r\n\r\nThe Map Change Dataset does not include 3D object annotations (which is a point of differentiation from the Argoverse 2 Sensor Dataset).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.\r\n\r\nSource: [Overview | Argoverse 2](https://www.argoverse.org/av2.html)\r\n\r\nImage Source: [Overview | Argoverse 2](https://www.argoverse.org/av2.html)","description_withheld":null,"homepage":"https://www.argoverse.org/av2.html","introduced_date":"2025-01-02","introduced_date_note":null,"introduced_by":{"paper":"/paper/argoverse-2-next-generation-datasets-for-self-1","title":"Argoverse 2: Next Generation Datasets for Self-Driving Perception and Forecasting","first_author":"Benjamin Wilson","url":null},"license":{"name":"CC BY-NC-SA 4.0","url":"https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode"},"modalities":[{"name":"Videos","url":"/datasets/modality/videos"},{"name":"LiDAR","url":"/datasets/modality/lidar"}],"tasks":[{"name":"Self-Supervised Learning","url":"/task/self-supervised-learning","datasets_with_task":"/datasets/task/self-supervised-learning"},{"name":"Motion Forecasting","url":"/task/motion-forecasting","datasets_with_task":"/datasets/task/motion-forecasting"}],"languages":[],"variants":["Argoverse 2 Map Change"],"data_loaders":[],"num_papers_in_archive":2,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
