Crowdsourced Map Dataset

The map dataset involved in the paper (Towards Secure and Efficient Crowdsourced Vector Map Updating on Cloud Platform)Description： (1) Folder `database_dataset`: Corresponds to the task publisher's original map database.(2) Folder `vehicle_dataset`: Crowdsourced vehicle collection trajectories, containing trajectories of 15 IDs.<br>The specific coordinate information of the dataset is in Table 5 of the paper.<br>Specifically, considering the confidentiality of vector map data, a geometric accuracy reduction method of has been applied to process the datasets, allowing for safer public release of the datasets while ensuring that the data remains usable.
