OGC 3D streaming Community Standard, I3S, receives update: public comment sought before approval
Latest version of I3S standard, used for streaming large 3D datasets, adds Point Cloud Scene Layer type, improved performance, and more.
8 October 2019: The Open Geospatial Consortium (OGC) seeks public comment on v1.1 of the candidate OGC Community Standard Indexed 3d Scene Layer (I3S) and Scene Layer Package Format Specification. I3S v1.0 was approved as an OGC Community standard in 2017 Since then new features have been developed and implemented by the I3S community. The candidate Community Standard was submitted by Esri.
I3S is used to stream large three-dimensional (3D) datasets and is designed for performance and scalability. I3S supports 3D geospatial content as well as the requisite coordinate reference systems and height models in conjunction with a rich set of layer types. I3S is designed to be cloud, web, and mobile friendly, and is based on modern web standards.
A single I3S dataset, referred to as a Scene Layer, is a container for arbitrarily large amounts of heterogeneously distributed 3D geographic data. Scene Layers are designed to be used in mobile, desktop, and server-based workflows and can be accessed over the web or as local files.
