CHW Dataset & GIS templates
This page provides quick access to Coastal Hazard Wheel (CHW) data resources and GIS templates that support consistent coastal classification, screening-level multi-hazard assessment, mapping, and integration into digital workflows.
The two links below support different ways of working with CHW:
CHW 3.0 Dataset (machine-readable)
Download the official CHW 3.0 dataset package (CSV) with documentation and machine metadata. Use this when you need a machine-readable reference for reproducible analysis, integration into tools and data pipelines, or AI-assisted workflows.
