When Predictions Match Reality: The Power of LiDAR for Flood Warnings

Michael Shillenn, of Quantum Spatial, details how North Carolina is managing flood risk through improved mapping and analysis of LiDAR data, made possible via the USGS’ 3D Elevation Program (3DEP). The article reveals the accuracy and precision of the flood analysis with real-life examples of floods that responded exactly as predicted by the LiDAR-derived flood modeling.  Read the article at GIS Lounge.

Excerpt:

The state uses LiDAR data to model hazards, identify vulnerabilities and perform impact assessments on buildings, as well as natural resources.

Most impressive, perhaps, is how accurately North Carolina can calculate anticipated flooding when hurricanes approach, which enables officials to offer precise guidance on evacuations and assist in emergency response.
