• Assessing critical infrastructure vulnerability using the infrastructure indicators mentioned in the description.
• Analyzing road network isolation risk from road-stream crossings and multiple natural hazards.
• Mapping soil erodibility and its co-occurrence with other hazards for land management planning.

Strengths

• Data is provided in multiple geospatial formats (points, polygons, polylines, rasters) for flexible analysis.
• Raster data has a defined 30x30 meter resolution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
