| # SAR-Sim — external assets |
|
|
| Large authoring assets for the **Structured Air-Route Simulation System (SAR-Sim)** |
| repository. They are published here because Git cannot carry them: the Shenzhen |
| whitebox scene alone is 599 MiB, and the imported city-model cache it references |
| adds about 1.05 GiB. |
|
|
| The main repository is self-contained for the study scene (`1.unity`, Xinjiekou). |
| Only the **joint-simulation demonstration** against the Shenzhen whitebox needs |
| the files in this dataset. |
|
|
| ## Contents |
|
|
| | Path in this dataset | Size | Destination in the repository | |
| |---|---|---| |
| | `Assets/Resources/Scenes/ShenzhenSKPWhitebox.unity` | 599 MiB | same relative path | |
| | `Assets/Resources/Scenes/ShenzhenSKPWhitebox.unity.meta` | 155 B | same relative path | |
| | `Assets/ImportedCityModels/` | ~1.05 GiB, 184 files | same relative path | |
| | `ue_import/` | ~321 MiB, 11 files | repository root | |
|
|
| `Assets/ImportedCityModels/` is kept wholesale on purpose: it holds the 97 `.meta` |
| files whose GUIDs the scene references. Copying the folder without them breaks |
| every building reference in the scene. |
|
|
| `ue_import/` holds the exported OBJ meshes used to rebuild the Unreal level |
| (`city/`), the locker props (`lockers/`) and the `TestArea` import script |
| (`testarea/`). Screenshots are not included. |
|
|
| ## How to use it |
|
|
| 1. Download this dataset (or only the parts you need) and copy the paths above |
| into the repository root, preserving the relative layout. |
| 2. Open `UnrealHost/SZ_TestArea/SZ_TestArea.uproject` in Unreal Engine 4.27 with |
| the AirSim 1.8.1 plugin installed under `Plugins/AirSim`. |
| 3. Copy `JointSimulation/settings.example.json` to `Documents/AirSim/settings.json`. |
| 4. Follow the joint-simulation section of the main `README.md`. |
|
|
| `ue_import/README_IMPORT.txt` and `ue_import/settings.json` carry the import |
| settings and the coordinate convention (Unreal X = north, Y = east, Z = up, in |
| centimetres, origin at WGS84 113.943589 E, 22.484868 N). |
|
|
| ## Licence and provenance |
|
|
| The city geometry derives from CADMapper and OpenStreetMap extracts of Shenzhen |
| (Nanshan, Futian, Longhua, Bao'an) and is redistributed here for research |
| reproduction. See the main repository's `LICENSE` and `THIRD_PARTY_NOTICES.md`. |
