An open specification for streaming massive heterogeneous 3D geospatial datasets.

3D Tiles v1.0 has entered the Open Geospatial Consortium (OGC) Community Standard process.


3D Tiles defines a spatial data structure and a set of tile formats designed for streaming and rendering 3D geospatial content such as Photogrammetry, 3D Buildings, BIM/CAD, Instanced Features, and Point Clouds.


Future Work

Additional tile formats are under development, including Vector Data (vctr) [#124] for geospatial features like points, lines, and polygons.

See the full roadmap issue for plans post version 1.0 [#309], as well as issues marked as 3D Tiles Next.
