HSIP US Cities: LiDAR and Imagery for Homeland Security and Disaster Preparedness

133+ U.S. cities had imagery and LiDAR collected to support threat analysis and disaster response for the Homeland Security community. The data was acquired by commercial contractors under the Homeland Security and Infrastructure Program, with publicly released data provided 'as is' and excluding U.S. Military Installation coverage. Some metadata about the collection is available from the USGS.

Use Cases

• Modeling flood risk and terrain analysis based on high-resolution elevation data.
• Planning emergency response routes based on detailed city topography.
• Analyzing critical infrastructure vulnerability based on geospatial baseline data.
• Supporting urban planning and development based on recurring LiDAR collects.

Strengths

• Covers 133+ U.S. cities, providing a broad geographic baseline.
• Includes both imagery and LiDAR data for multi-source analysis.
• Data was collected under a formal federal program (HSIP) for a specific operational purpose.

Limitations

• Row count, file size, and column-level documentation are unknown.
• Last update date is unknown; freshness unverified.
• Publicly released data is provided 'as is' and excludes coverage of U.S. Military Installations.
