Each year, snow avalanches hit populated areas and parts of the transport network in the Norwegian mountain regions, leading to loss of lives and the damaging of buildings and infrastructure. We present the results of a feasibility study on the operation of a service providing the National Public Roads Administration (NPRA) with hind-cast avalanche inventory data on a local-to-regional scale during the course of the winter season, and as soon as possible after major avalanche events. We have explored the use of imagery from high-resolution and very-highresolution space-borne satellites applying manual mapping and automated image segmentation.
