AI-supported early warning for natural hazards and critical infrastructure

Off-grid sensors measure where debris flows, floods and slope movements begin. GeoSenseAI® turns those readings into a live situation overview that municipalities, authorities and infrastructure operators can act on.

Hazards build up in the catchment, long before they reach the protective structure

Heavy rain, snowmelt, rising water levels and sediment transport often change a catchment hours before an event reaches homes, roads or railway lines. Measuring only at the valley floor means seeing that development late.

That is why GMD® starts where the process starts: with self-powered sensors in the channel, on the slope and on the rock face, streaming data to GeoSenseAI® around the clock.

From reading to decision in three stages

Early warning is more than an alarm. The system supports decision-makers from continuous situational awareness through to documenting what happened.

  1. Continuously

    Nowcasting

    Water level, rainfall and movement data are condensed into a traffic-light status for each catchment, so a pre-alert can be raised early and response teams put on standby.

  2. When agreed thresholds are exceeded

    Early warning

    GeoSenseAI® automatically notifies the designated contacts via app, text message or email. The responsible authorities decide what happens next. [GMD MUSS PRÜFEN: confirm alert channels]

  3. After the event

    Situation overview

    Drone surveys and terrain comparison show what has changed and which buildings and routes are affected – without sending staff into the danger zone. [GMD MUSS PRÜFEN: maturity: automated, sensor-triggered drone flights currently in development/pilot]

GMD® systems provide measurements and decision support. They do not replace official warnings or the assessments and operational decisions of the responsible authorities and emergency services.

Hazards we monitor

Each process needs its own measurements. The colour identifies the hazard type, consistently across this website and in GeoSenseAI®.

  • Debris flows and torrents

    Water level, rainfall and ground vibration in the channel to detect sediment transport and the early stages of a debris flow.

  • Heavy rain and flooding

    Water level, flow velocity and rainfall in tributaries and urban streams – including signs of blockages at bridges and culverts.

  • Rockfall

    Automated detection of vibration and micro-movement on rock faces, masonry and protective structures.

  • Slope movement

    Long-term tracking of tilt, displacement and soil parameters to make slow trends visible.

  • Avalanches

    Additional measurements to support the assessments of avalanche commissions and operators. [GMD MUSS PRÜFEN: confirm avalanche scope]

  • Wildfire

    Sensor-based early detection in forests at risk. [GMD MUSS PRÜFEN: confirm maturity of wildfire offering]

One partner for sensors, platform and operation

GMD® designs its own measurement hardware, installs it in the field and runs the system as a service – so municipalities don't need in-house specialists.

Off-grid edge IoT sensors
Self-powered sensors for hydrology, meteorology and geotechnics – even where there is no power or cabling.
GeoSenseAI®
The platform combines sensor, weather and geodata, shows how the situation is developing and issues alerts based on thresholds you define.
Drones and digital twin
Autonomous drones and digital terrain models reveal change and create a reliable record.
Installation, maintenance, operation
Planning, installation in the channel or on the rock face, calibration and ongoing maintenance by the GMD® team.

Who we work with

Municipalities and authorities
A shared situation overview for crisis teams and fire services, and a traceable basis for closure and reopening decisions.
Rail and road
Monitoring of torrents, embankments and rockfall zones along transport corridors.
Ski resorts and tourism
Channel and slope monitoring above resorts and lifts, plus data-driven visitor flow management.
Water supply
Off-grid monitoring of spring discharge, water level and consumption – even at high altitude.
Insurers
Measured data and event records to support risk assessment and claims handling.

Case studies

Selected projects with partners in Graubünden (Switzerland) and Tyrol (Austria).

Rather than measuring at the structure, GMD® monitors the entire catchment of roughly 14 km² in real time – off-grid, year-round and without existing infrastructure on site.
