Description
Multi-hazard intensity fields for Galveston Island, Texas, created by the NIST Community Resilience Center of Excellence and updated in April 2026. The collection includes simulated storm rasters for 100-year and 500-year return-period events, FEMA flood grids, LiDAR topography, and vector data for infrastructure and social systems. These datasets support per-asset hazard retrieval for buildings, utility poles, roads, and bridges.
Use Cases
Assessing hurricane-induced infrastructure damage based on simulated flood depth, wave height, and wind velocity rasters.
Optimizing mitigation strategies for coastal communities based on multi-hazard intensity fields and built environment data.
Analyzing equity in disaster recovery based on tract-level social vulnerability indicators and hazard exposure.
Modeling long-term recovery of interdependent infrastructure systems based on detailed electric power and transportation network data.
Strengths
Includes hazard simulations for both 100-year (1% AEP) and 500-year (0.2% AEP) return-period storm events.
Integrates multiple data types: simulated rasters, FEMA flood grids, LiDAR DEM, and vector shapefiles for a comprehensive testbed.
Provides companion code on GitHub for reproducing the full analysis pipeline, including damage assessment and optimization.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count and file sizes are unknown, which may limit suitability assessment.
Data is geographically specific to Galveston Island, Texas, limiting direct applicability to other regions.
