EGIS is exploring a geospatial-to-OpenUSD terrain export workflow. We have published a short technical demo showing our current conversion pipeline, stage organization, and loading results:  
[\*[https://www.youtube.com/watch?v=\_Ea9uLfWS7Q\*\\\\\\\\\\\\\\\](https://www.youtube.com/watch?v=_Ea9uLfWS7Q*%5C%5C%5C%5C%5C%5C%5C%5C%5C%5C%5C%5C%5C%5C%5C)]

Current scope:

- [SOURCE DATA TYPE] to OpenUSD terrain conversion
- [STAGE / ASSET ORGANIZATION SUMMARY]
- Loading and visual inspection in [TESTED ENVIRONMENT]

This is an early proof of concept. It is not presented as an NVIDIA-validated or fully simulation-ready workflow. We would particularly value community feedback on:

1. Recommended conventions for metersPerUnit and upAxis validation
2. Representation of projected CRS and local origin metadata
3. Reference/payload/LOD organization for large terrain
4. Minimum validation information useful for downstream simulation workflows

A public technical overview is available here:

Thank you for any guidance, relevant examples, or specifications we should review .
