Indexed 3D Scene Layers (I3S) – What is it ?
• An open specification for storage and transmission of large, heterogeneous 3D
geospatial data sets.
- https://github.com/Esri/i3s-spec
• Designed to be Cloud, Web and Mobile friendly based on modern web standards
and best practices.
• Supporting 3D geospatial content, various coordinate systems along with a rich set
of layer types.
• Without any commercial software dependencies.
Designed for 3D Geospatial
