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).
