**(15) Backlink intersections of hazard potential and damage potential to release areas:**In the case of avalanches all the transition zones that intersect with infrastructure have to be traced back to the corresponding release area. Using Raster in ArcGIS, this can be done by inverting the DEM and performing a new cost path analysis starting from the intersected damage potential areas. Finally, by combining the avalanche release and transition zones as well as rockfall transition zones that possibly harm infrastructure we are able to identify Object-protecting forest. | **(15) Backlink intersections of hazard potential and damage potential to release areas:**In the case of avalanches all the transition zones that intersect with infrastructure have to be traced back to the corresponding release area.
