<!-- Provide a quick summary of the dataset. -->

The OCFBench dataset is curated in the paper [**Occ4cast: LiDAR-based 4D Occupancy Completion and Forecasting**](https://arxiv.org/abs/2310.11239).
The dataset is processed from public autonomous driving data to support the training and evaluation of the novel **occupancy completion and forecasting (OCF)** task.

# Uses

Please download each `.sqf` file from individual directories and mount them to local system for usage.

For larger files that are splited into several parts, please run the following code to merge the parts before mounting:

```
cat output_prefix_* > merged.sqf
```

Please refer to our [GitHub repository](https://github.com/ai4ce/Occ4cast/) for dataset structure and loading details.
