Geohazard Survey from Air – remote decision support with focus on avalanche applications


Every year in Norway, geohazards pose a serious threat to the transport network. Road closures caused by snow avalanches, landslides, and rockfalls incur high economic costs and greatly impact the reliability of Norway’s critical transport network. The GEOSFAIR project owner, the Norwegian Public Roads Administration (NPRA), is responsible for maintaining important routes that are threatened by snow avalanches. Keeping these roads open requires costly operations to assess and mitigate snow avalanche risk. The widespread coverage of the transport network and growing volumes of travellers, as well as climate changes that have resulted in more severe, more frequent, and less predictable geohazards, have increased the NPRA’s mitigation costs. In addition, closing transport infrastructure for extensive periods has severe societal and financial consequences because in many places there is little or no road redundancy. Mitigation measures tend to be reactive, based on immediate risk rather than on proactive monitoring. Therefore, there is an urgent need for more cost-effective and innovative methods for assessing and mitigating geohazards along NPRA’s network. Rising geohazard assessment costs, in combination with a climate-impacted, changing risk picture, are the motivation for the GEOSFAIR application. This proposal recognizes the growing capabilities of unmanned aircraft systems (UAS), payloads to evaluate snow conditions, and software to use those data to support decision making. The NPRA has identified the following research and innovation areas for GEOSFAIR that will significantly create value: 1) Utilization of new, automated UAS technology to survey hazardous terrain while reducing the need for costly manned helicopter flights and manual observations; 2) Improvement in the accuracy and reliability of geohazards data; and 3) Implementation of structured digitization strategies to remotely monitor avalanche sites and to support the NPRA ‘s roadway closure decisions.
