Hello Oracle Spatial Community,
I am currently working on integrating 3D spatial data (formats such as IFC, CityGML, OBJ, GLTF/GLB, etc.) into Oracle Spatial from a .NET application, and I would appreciate your guidance on the following:
- Data ingestion / mapping external formats
- What is the recommended workflow for mapping common 3D formats (IFC, CityGML, OBJ, GLTF, etc.) into valid SDO_GEOMETRY objects?
- Are there any Oracle-provided or community-proven libraries/tools that can assist with this process, particularly in the .NET environment?
- Intermediate formats
- Is there a suggested intermediate exchange format (e.g., WKT with Z, CityJSON, …) that can simplify the transformation pipeline into Oracle Spatial?
- Best practices / reference workflows
- Are there any published best practices, examples, or reference pipelines for handling complex 3D model ingestion into Oracle Spatial, especially when dealing with .NET client applications?
- For 2D geometries, we can easily ingest data using expressions like:
SDO_GEOMETRY('WKT', 8307)
However, in 3D this approach seems limited, since WKT does not provide direct support for solid volumetric objects. Could you please confirm the best practice or recommended alternative for handling 3D solids in Oracle Spatial.
Thank you very much for your insights and guidance!
