ArcGIS Script for Assessing Hazards along Lifelines or Points

Format: Python script, .py

Date: 03/01/2018

Description: The Raster to Line tool extracts the values of a hazard raster, such as the landslide triggering or displacement maps included in OHELP, and assigns their values to a lifeline or network of lifelines. An additional search distance option allows users to identify nearby hazards that do not intersect with the lifelines, and a search for statistic option gives users a choice to identify nearby trends or extremes in hazard.
