+
+EmbodiedNav-Bench is a goal-oriented embodied navigation benchmark for evaluating spatial action in urban 3D airspace. The benchmark contains 5,037 high-quality navigation trajectories with natural-language navigation goals, initial drone poses, target positions, and ground-truth 3D trajectories.
+
+This Hugging Face repository hosts the dataset artifacts. The accompanying project code, simulator setup, media examples, and evaluation scripts are maintained in the GitHub repository: https://github.com/serenditipy-AC/Embodied-Navigation-Bench
+
+## Dataset Summary
+
+The benchmark contains 5,037 goal-oriented navigation trajectories. Each sample corresponds to one navigation task in an urban 3D environment, with a natural-language goal description and a human-collected ground-truth trajectory.
+
+The dataset is intended for evaluating embodied navigation, spatial reasoning, and multimodal decision-making models in urban airspace scenarios.
+
+## Repository Contents
+
+| Path | Description |
+| :-- | :-- |
+| `navi_data.pkl` | Canonical PKL file for evaluation. |
+| `viewer-00000-of-00001.parquet` | Parquet representation for the Hugging Face Dataset Viewer table. |
+| `images/` | Trajectory-aligned image release, distributed as five ZIP archives plus a manifest file. |
+
+## Data Fields
+
+The canonical PKL file stores a list of Python dictionaries. Each sample contains the following fields:
+
+| Field | Type | Description |
+| :-- | :-- | :-- |
+| `sample_index` | `int` | Sample index used for viewer browsing and image archive alignment. |
+| `start_pos` | `float[3]` | Initial drone world position `(x, y, z)`. |
+| `start_rot` | `float[3]` | Initial drone orientation `(roll, pitch, yaw)` in radians. |
+| `start_ang` | `float` | Initial camera gimbal angle in degrees. |
+| `task_desc` | `str` | Natural-language navigation instruction. |
+| `target_pos` | `float[3]` | Target world position `(x, y, z)`. |
+| `gt_traj` | `float[N,3]` | Ground-truth trajectory points. |
+| `gt_traj_len` | `float` | Ground-truth trajectory length. |
+
+The Parquet table includes the same structured fields and additional convenience columns such as `sample_index`, `start_x`, `start_y`, `start_z`, `target_x`, `target_y`, `target_z`, and `gt_traj_num_points`. The Parquet file is provided for browsing and visualization in the Hugging Face Dataset Viewer.
+
+## Trajectory-Aligned Images
+
+Trajectory-aligned image archives are available under [`images/`](https://huggingface.co/datasets/EmbodiedCity/EmbodiedNav-Bench/tree/main/images).
+
+This release is about 56.7 GB and is distributed as five ZIP archives together with `merged_upload_images_zip_manifest.json`.
+
+After extraction, folders `0-5036` correspond directly to the `sample_index` field in `navi_data.pkl` and the viewer table.
+
+| Archive | Sample index range |
+| :-- | :-- |
+| `merged_upload_images_part01_0000-1007.zip` | `0-1007` |
+| `merged_upload_images_part02_1008-2015.zip` | `1008-2015` |
+| `merged_upload_images_part03_2016-3022.zip` | `2016-3022` |
+| `merged_upload_images_part04_3023-4029.zip` | `3023-4029` |
+| `merged_upload_images_part05_4030-5036.zip` | `4030-5036` |
+
+## Usage
+
+<!-- The Dataset Viewer-compatible table can be loaded with the `datasets` library:
+
+```python
+from datasets import load_dataset
+
+ds = load_dataset("EmbodiedCity/EmbodiedNav-Bench", split="viewer")
+print(ds[0])
+```
+ -->
+For evaluation, use `navi_data.pkl` as the canonical data file and follow the setup instructions in the GitHub project repository.
