--- title: "Cities: contact | Nexus Observatory" description: "Contact and seller of record for cities and urban systems: Street flooding, Air quality and urban heat, Structural condition of public assets…" url: https://observatory.global/industries/cities/contact/ publisher: Nexus Observatory Inc. updated: 2026-11-02 --- Cities: the city measured block by block: its team and how to reach it. The loop, step by step: 1. Gates open and the stadium starts to fill. 2. The chain from source to console stands ready. 3. A crowd surge builds toward the north gate. 4. Cameras count the flow at every gate. 5. Each reading is stamped with time and place. 6. Counts reach the edge over the stadium radio. 7. Relays carry the packets without reading them. 8. Signatures are checked before any model runs. 9. The edge model estimates density per gate. 10. The edge releases confirmed results only. 11. The control room sees the density map. 12. The alert arrives with its evidence attached. 13. Stewards open the south gate and capacity rises. 14. Instruments confirm the response took effect. 15. Record, proof and action are archived together. 16. The crowd spreads out and the radio relaxes. 01 / 16 Gates open and the stadium starts to fill [Nexus Observatory](https://observatory.global/) / [Cities](https://observatory.global/industries/cities/) / **Contact** # Talk to the cities team.

Who sells, and who owns the data? Nexus Observatory Inc. is the seller of record. The data your systems collect stays yours, under the licence you choose. Do we have to buy hardware? No. We deliver as a managed service, a data licence or a system you own. Can we start small? Yes. Start with one station or one site, then grow to a fleet and a network on the same open protocol, without replacing what you bought. Which standards do the systems meet? Each system is drawn against the open protocol and the standards it is composed from, listed on this page. What happens after go-live? We run the systems to a written service level, with monitoring, repair and an evidence trail, or train your team to run them. **03** Company ## Who answers.
