Climate hazard exposure indicators were developed based on zonal statistics along each feature as detailed in the DDP-8 Data Dictionary and the Technical Report. Risk attributes were assigned based on the exposure indicators and assumptions listed in the Technical Report using Python scripts.
Note: All SHS features that are marked as bridges (i.e., asset_type = "Bridge") are included in this dataset. All SHS features that are marked as tunnels (i.e., a non-empty value for tunnel_id and an empty value for tunnel_near_segment)
