Project allows Chordant and Swisscom to contribute data integration, visualization and mobile data expertise to public safety effort for municipal governments

"Early warning systems like this are vital for public safety and disaster prevention, not only for the case of debris flows, but also for any natural disaster," -- Mika Rasinkangas, president of Chordant.

Chordant today announced a collaboration with Swisscom Broadcast for the real-time reporting and visualization that municipalities can leverage to better understand, predict and provide early warning for Alpine mass movements, like debris flows. This collaboration involves the use of Chordant's data hub to collect, synthesize and visualize both real-time and historical data from a variety of seismological, meteorological and other environmental sources. This monitoring and alarm system has already been implemented and future applications are now being developed.

One of the most mountainous countries in the world, Switzerland is a natural place for such a system to emerge, because significant university research exists and is constantly being expanded upon throughout the region. " IoT Solutions with dense sensor networks combined with different data sources offer a new way to predict and raise alarms about natural hazards, and, allow the most critical areas with exposed people to be targeted first,” said Olivier Anthamatten, Head of Business Development, Swisscom Broadcast.

"Early warning systems like this are vital for public safety and disaster prevention, not only for the case of debris flows, but also for any natural disaster," said Mika Rasinkangas, president of Chordant.

This system was designed initially to help municipal governments, emergency response units and infrastructure managers make better planning decisions, as well as more rapidly respond to disasters when they occur. Future iterations of this solution can be used to deliver real-time information and status updates to the general public. While this collaboration was designed for slope failure, landslides and the resulting debris flows, similar applications for this technology could be developed for avalanches, river flooding, and other extreme weather conditions where visualization of the interplay between weather information and geographic data is useful.

This collaboration between Chordant and Swisscom Broadcast enables a public-private partnership in Switzerland that integrates data from a number of previously siloed sources. Such integration helps provide tangible and potentially life-saving outcomes for citizens and visitors to Swiss mountainous regions. Data sources in this collaboration include seismological and meteorological station data, seismic origin heatmaps, debris flow detections, mobile data device count information, environmental imaging, and infrasonic analysis. The visualization allows for historical views, as well as real-time models to be run during a disaster response event. Chordant and Swisscom Broadcast are collaborating on this project with key contributions being made by the Laboratory of Hydraulics, Hydrology and Glaciology (VAW) and the Swiss Seismological Service, both part of the Swiss Federal Institute of Technology (ETH Zurich).

A demonstration of this early warning system will be featured at the upcoming Smart City Expo World Congress 2019, November 19-21 in Barcelona. Interested parties attending this event are invited to visit Chordant’s booth in the USA Pavilion, Booth B207.
