Dear Support Team,

I am building an end-to-end drone mapping pipeline for city-scale **3D Gaussian Splatting (3DGS)**. My ultimate goal is to publish the final models as **3D Tiles** into **ArcGIS Pro / Enterprise** , which strictly requires accurate **Real-World Georeferenced Coordinates** and a **Z-up orientation**.

Currently, I am facing a critical issue where the trained model loses its geographical location and orientation during the pipeline transition.

**My Current Workflow**

1. **SfM / Alignment:** RealityScan (Version 2.2.0.119430) → Exported to COLMAP text format.
2. **3DGS Training & Export:** LichtFeld Studio (LFC Studio).

**The Problem**

When I export the COLMAP files from RealityScan and import them into LichtFeld Studio, the software trains the model, but it **does not recognize, bake, or preserve the project’s real-world geographic location**. As a result, the final PLY or 3D Tiles do not land on their correct geographic coordinates in GIS environments.

I suspect I am either using the wrong COLMAP export presets in RealityScan, or the georeferencing metadata (EXIF/GPS) is being stripped/misaligned during the handoff to LichtFeld Studio.

**My Questions**

1. **RealityScan Export Presets:** What are the best export settings or presets in RealityScan (v2.2.0) to ensure that camera GPS/GCP data is properly baked into the COLMAP text export?
2. **Georeferencing & Transformation:** What is the best practice to bake the georeferencing (EPSG / WGS84) and **Z-up rotation** directly into the 3DGS model (including Spherical Harmonics rotation) within this specific pipeline so it perfectly aligns with real-world coordinates?
3. **LichtFeld Studio Compatibility:** Is there a specific alignment step, transform matrix, or configuration file I need to apply during or after the COLMAP import in LichtFeld Studio to maintain the coordinate system for 3D Tiles export?

Thank you for your time and guidance. I look forward to your expert recommendations to help resolve this alignment bottleneck. Below is my presets for Colmap Export
