Site twins measured in 3D…" url: https://observatory.global/digital-twins/areas/ publisher: Nexus Observatory Inc. updated: 2026-11-02 --- [Nexus Observatory](https://observatory.global/) / [Digital twins and simulation](https://observatory.global/digital-twins/) / **Areas** # Digital twins and simulation, area by area. Each area of the platform has its own page: the systems in it, the standards it is drawn against, the industries it serves and how we deliver it. [Plan with us](https://observatory.global/digital-twins/contact/deployment/) [Technologies](https://observatory.global/digital-twins/technologies/) Areas · **5** Technologies · **197** Industries · **9** **01** Areas ## Digital twins and simulation, area by area. Choose an area for its systems, standards, the industries it serves and how we deliver it.

Enterprise by contract. The open layer lives on the main site, free to use and build on. Enterprise services are delivered under contract by Nexus Observatory Inc. Open, on the main site - Simulation methods with worked examples - Open terrain and grid layers Enterprise, on this site - Drone survey and 3D site twins - Network planning studies - Scenario studies **03** On this site ## Where to go next.
