The Open Geospatial Consortium (OGC) seeks public comment on the 3D Tiles Specification 1.0 candidate community standard.
It’s a bit of a mouthful, but the OGC’s 3D Tiles specification 1.0 candidate community standard (3D Tiles) is a publicly available, open specification for streaming massive heterogeneous 3D geospatial datasets for visualisation.
Designed to expand beyond existing 2D and 2.5D streaming of map tiles and terrain, the 3D Tiles specification supports 3D models such as point clouds, 3D buildings (exterior and interior), trees, imagery, BIM/CAD models, and terrain, and is currently implemented in over a dozen software products.
3D Tiles defines a spatial data structure and a set of tile formats designed for 3D, optimised for streaming and rendering with four tile formats: Batched 3D Models, Instanced 3D Models, Point Clouds and Composite.
Confused about the standards part? In OGC parlance, a community standard is an official standard of the OGC, developed and maintained external to the OGC. The originator of the standard brings to OGC a ‘snapshot’ of their work that is then endorsed by OGC membership as a stable, widely implemented standard that becomes part of the OGC Standards Baseline.
The candidate 3D Tiles Specification 1.0 community standard is available for review and comment on the OGC Portal. Comments are due by 1 August 2018 and should be submitted via the method outlined on the 3D Tiles Community Standard’s request page.
