--- title: "Public safety: specialized fields | Nexus Observatory" description: "Specialized fields for public safety and emergency management: Rainfall, river level and soil moisture, Fire weather, smoke and ignition…" url: https://observatory.global/industries/public-safety/fields/ publisher: Nexus Observatory Inc. updated: 2026-11-02 --- [Nexus Observatory](https://observatory.global/) / [Public safety](https://observatory.global/industries/public-safety/) / **Specialized fields** # Public safety, field by field. Public safety is a set of hazards that each give a different warning time and call for a different response. A wildfire seen from a tower, a flash flood rising in a street, a slope starting to move, an earthquake's first waves, an avalanche above a road and an incident where crews need their own network each measure different things for different agencies. Each field below has its own stack, radio, power and crew work, from the first order to the running operation.

Each field page sets out the operating context and hazards, what must be measured and under which rules, the stack from base unit to network, the work from order to operation, the data products and the cited sources. [Specialized field Wildfire detection and responseSmoke detection from towers, fire weather and danger, thermal confirmation and satellite hotspots, on microwave and satellite to the fire agency's dispatch, so a start is seen in minutes.The full field →](https://observatory.global/industries/public-safety/wildfire/) [Specialized field Flash and urban floodsRain and water depth in streets, culverts and small streams, with cameras at known flood points, on LoRaWAN and cellular, so warnings reach people in the minutes a flash flood allows.The full field →](https://observatory.global/industries/public-safety/flash-floods/) [Specialized field Landslides and debris flowsGround movement by GNSS, pore pressure and rainfall thresholds, ground vibration for debris flows, on LoRaWAN and satellite from unstable slopes to the agency that warns and closes roads.The full field →](https://observatory.global/industries/public-safety/landslides/) [Specialized field Earthquakes and early warningStrong-motion and broadband seismometers, GNSS for large events, structural response in key buildings, on fibre and cellular with timing that lets a warning outrun the shaking.The full field →](https://observatory.global/industries/public-safety/earthquakes/) [Specialized field Avalanches and mountain roadsSnow and weather on the slopes, avalanche detection by radar and infrasound, cameras on the paths, on microwave and satellite to the road and the avalanche service, so roads close before the snow comes down.The full field →](https://observatory.global/industries/public-safety/avalanches/) [Specialized field Incident response and deployable networksA network that arrives with the crews: cell on wheels, satellite, mesh, drones, gas and thermal sensing at the scene, so incident command sees and talks when local networks are down.The full field →](https://observatory.global/industries/public-safety/incident-response/) **02** Solution bundles ## Start with one unit. Grow to a network. The same systems at every scale, on the open protocol, so nothing you buy is replaced as you grow. 1. **01** Base unit One station or node, specified for this industry: instruments, power, enclosure and backhaul. [Build a station →](https://observatory.global/studio/builder/) 2. **02** Site A surveyed, commissioned site with its timing, its links and the evidence file a buyer can audit. [Plan a site →](https://observatory.global/contact/deployment/) 3. **03** Fleet Many sites run as one service: one plan, one update path, one evidence trail, one service level. [Managed offers →](https://observatory.global/industries/public-safety/solutions/) 4. **04** Network Fleets that federate with partner grids through the open protocol, owner by owner. [The open protocol →](https://observatory.global/protocol/) ### Ready when you are. Plan a deployment, configure a station or talk to sales. Every request reaches the team that answers it.
