The package provides reusable functions\nfor preparing hazard zones, generating road-based evacuation\norigin points, identifying escape/safety points, creating\nslope-based conductance surfaces, calculating least-cost\ndistance to safety, and converting distance outputs into\nevacuation-time polygons. It is designed to support workflows\nlike tsunami evacuation modeling while remaining adaptable to\nother regions and hazards. Tsunami-specific helpers support\nseparate land-only hazard zones, water-combined escape zones,\nroad-aware escape boundaries, and study-area inset cropping for\nquality assurance and quality control.
