Water · Use cases Every catchment, gauged Stream gauges and rain networks, groundwater and water-quality sensing, flood observing for utilities and basin authorities, and Earth observation of reservoirs, snow and inundation, delivered with the completeness a hydrologist checks first. Needs: river level and discharge, rainfall and snow, groundwater, water quality and inundation extent. 2. Use case Street flood observatory Ultrasonic depth sensors on poles report street-level water depth as open data and alerts. For cities, emergency management agencies and universities. Data products: street-level water depth time series and open data feed and alerts to emergency management and 311. Drawn against OGC SensorThings API 1.1 and Municipal open-data terms. StandardsOGC SensorThings API 1.1 · Municipal open-data terms 3. Use case Low-cost stream gauge network Radar or pressure level sensors with low-power radio and solar power, as a cheaper tier beside a national gauge network. For provinces and states, watershed boards. Data products: stage and flow time series and flood-warning inputs, labelled supplementary. Drawn against WMO hydrological observing practices and National gauge standards. StandardsWMO hydrological observing practices · National gauge standards 4. Use case Hybrid air-quality observatory A few reference analysers and many low-cost nodes, with co-location calibration and an open-data feed. For cities, public-health units, school districts. Data products: air-quality index and hyperlocal maps, labelled supplementary, calibrated time series with quality flags and publication route to an open air-quality aggregator. StandardsEU Directive 2024/2881 (ambient air quality) · CEN/TS 17660 (sensor systems) · US EPA FEM/FRM reference methods 5. Use case Mine site private 5G and environmental monitoring A standalone 5G core, radios across the pit and edge compute for autonomy, with dust, vibration, slope and weather sensing for environmental records. For mining companies and their contractors. Data products: autonomy and safety communications records and environmental monitoring records (dust, blast vibration, slope, tailings). Standards3GPP Rel-16/17 URLLC · ISO 17757 (autonomous mining machinery safety) · GISTM (tailings) · ISA/IEC 62443 6. Use case Deployable incident observatory A trailer or vehicle with a cell on wheels, satellite backhaul, a mesh kit, a drone and weather and air-quality nodes for an incident base. For emergency management agencies, event organisers, utilities. Data products: incident-base connectivity and situational observations. Drawn against 3GPP LTE/NR, OASIS CAP 1.2 and National incident-management systems. Standards3GPP LTE/NR · OASIS CAP 1.2 · National incident-management systems 7. Use case Research-infrastructure gap node A standardised observation package with a FAIR data pipeline, built to extend a research infrastructure's coverage. For research infrastructures and universities. Data products: FAIR datasets delivered to research-infrastructure portals. Drawn against ICOS and eLTER quality levels, netCDF/CF and OGC SensorThings API. StandardsICOS and eLTER quality levels · netCDF/CF · OGC SensorThings API 8. Use case Avalanche detection site Doppler radar, infrasound and geophones with a snow and wind station, feeding a road or resort control room. For resorts and road authorities. Data products: release confirmation and road-closure inputs. Drawn against Cantonal and provincial avalanche-safety codes. It runs on the open Observatory Protocol, so other providers can join. StandardsCantonal and provincial avalanche-safety codes 9. Trust Every node proves what it is A node joins only after its hardware root of trust answers an attestation challenge. Keys stay in secure hardware, software arrives signed, and every reading carries a signature, so its origin can be checked by anyone downstream without asking us. 10. Time and place Every reading carries when and where Readings are stamped against a disciplined clock, from satellite time or a PTP grandmaster, together with the station position and its siting record. When time or position is degraded, the record says so instead of hiding it, and every analyst downstream sees the same warning. 11. How it scales One base unit, repeated A programme starts with one base node and the instruments it reads. A station adds power and radio, a site adds a relay, a fleet repeats the proven site across many places, and a network federates fleets through edge and core. Capacity grows by adding units, never by replacing what works. 12. What you get Hydrometeorological and flood observing networks Stream gauges, rain gauges, weather radar and automatic weather stations built to WMO practice, reporting through WIS 2.0 where the agency requires it. Delivered as hardware + software, managed service and build-operate-transfer, for national meteorological and hydrological services, river-basin agencies, utilities.
