Network twinsCoverage, capacity, power and timing, simulated.
Network twins, inside Digital twins and simulation: city and site models, 3D Tiles and scene layers, BIM and asset information, photogrammetry and reality capture and more. Every item is traced to its specification, from OGC CityGML 3.0 Conceptual Model to OGC 3D Tiles 1.1 (Community Standard), and runs on the open Observatory Protocol.

01What it is
3D, BIM and digital twins.
The reference frames, formats, services, analysis methods, machine learning and 3D models that turn observations into located, queryable and decision-ready geographic information. Each technology below carries what it is, what we do with it, and the standard it is drawn against.
