+
+Yet another distribution of the dataset from the paper: [📜 Video2BEV](https://arxiv.org/abs/2411.13610)
+
+## Package and Data Structure
+
+### Package
+
+The dataset is archived using Zstandard compression, e.g., `train-shard00.tar.zst` or `test-shard01.tar.zst`.
+
+- Extract with the command
+
+```bash
+tar xaf train-shard00.tar.zst
+```
+
+- Extract all
+
+```bash
+for file in {train,test}-shard*.tar.zst; do
+  tar xaf "$file"
+done
+```
+
+### Data Structure
+
+A dataset entry looks like:
+

+
+### Guarantees
+
+- **ID** All IDs are zero-padded 4-digit strings (`%04d`) and fall in the range 0000-1651.
+- **Drone** There are exactly two videos, `angle-30.mp4` and `angle-45.mp4`, under `${split}/${id}/drone/`. (H.264, 10 FPS, 512×512)
+- **Satellite** There is exactly one JPEG file under `${split}/${id}/satellite/${id}.jpg`.
+- **Google** Only the training split ships with `google/` folders, and not every ID has one.
+
+### Exceptions
+
+- `test/0274/street/` contains some images that appear to belong in a `google/` folder and do not follow the usual naming convention.
+  This may be due to an issue in the original packaging. Since this repository is a reorganization and redistribution (not the original release), the files are provided as-is.
+- In the test split, 158 IDs have no `street/` folder.
