| ## About |
| Reliable integration of prior information is crucial for selfverifying and self-updating HD maps. However, no public dataset includes the required triplet of prior maps, current maps, and sensor data. As a result, existing methods must rely on synthetic priors, which create inconsistencies and lead to a significant sim2real gap. To address this, we introduce ArgoTweak, the first dataset to complete the triplet with realistic map priors. At its core, ArgoTweak employs a bijective mapping framework, breaking down large-scale modifications into fine-grained atomic changes at the map element level, thus ensuring interpretability. This paradigm shift enables accurate change detection and integration while preserving unchanged elements with high fidelity. |

| ## [v1.0.0] – 2025-08-01 |
| 🚀 Official release of the ArgoTweak dataset |
| The numbers in the paper have been achieved with a legacy version (v0) of ArgoTweak. The official version v1 has been improved as follows: |
|
|
| - Refined lane segment connectivities (predecessors/successors) in multiple scenes |
| - Annotated changes in the test split that were not identified in the original dataset [https://github.com/johnwlambert/tbv/blob/main/labeled_data/tbv_val_split_annotations.json](https://github.com/johnwlambert/tbv/blob/main/labeled_data/tbv_val_split_annotations.json) |
| - Improved consistencies of geometry annotations in several maps |
| - Removed incorrect intersection status of isolated lane segments |
| |
| If, for any reason, you require access to the legacy version (v0) of ArgoTweak, please contact the authors directly. |
