OGC seeks public comment on proposal to revise Indexed 3D Scene Layers (I3S) Community Standard

 

 

 

I3S is used to stream 3D geospatial content of any size to mobile, web and desktop clients.

14 January 2021: The Open Geospatial Consortium (OGC) seeks public comment on the proposal for a revision to the OGC Indexed 3D Scene Layers (I3S) Community Standard. The proposed revision is defined in the I3S Version 1.2 Community Standard Work Item Justification document. Comments are due by February 15, 2021.

I3S enables the streaming and storage of arbitrarily large amounts of 3D geographic data. An I3S dataset, referred to as a Scene Layer, can consist of millions of discrete 3D objects with attributes, integrated surface meshes, symbolized points, or billions of point cloud data covering vast geographic areas. Designed for performance and scalability, a scene layer enables the efficient encoding and transmission of various types of geospatial content for an interactive visualization experience on web browsers, mobile, and desktop apps for both offline and online access. A Scene Layer can be accessed in the form of a web service or Scene Layer Package (SLPK) – a file-based exchange format.

I3S is web and cloud friendly and is rooted in modern standards and technological advancements in the areas of 3D graphics, data structuring, and mesh and texture compression. I3S is accessible for efficient client-side filtering. I3S empowers city and local governments, content providers, and GIS professionals to share scene layers consisting of terabytes of nation-wide point cloud coverage, city and site scale 3D mesh data collected at frequent intervals, 3D planning scenarios fusing both ‘as built’ and modeled information, and more. The increased accessibility and ease of consumption of geospatial content by both domain experts as well as casual users is being rapidly accelerated by standards such as I3S.

The proposed revisions for I3S version 1.2 include:

These new enhancements are based on the Esri I3S version 1.7 product release.  OGC I3S v1.2 is backwards compatible with OGC I3S v1.1.

The work item proposal for the Indexed 3D Scene Layers (I3S) v1.2 Community Standard is available for review and comment on the OGC Portal. Comments are due by February 15, 2021, and should be submitted via the method outlined on the Indexed 3D Scene Layers (I3S) v1.2 Community Standard’s public comment request page.
