The Texas Department of Transportation maintains 38,000 miles of roads in the Austin area, some of which deal with major flooding issues.
To be proactive with flood response, managers need accurate road elevation maps. They used a combination of lidar and NOAA’s land cover data to analyze a variety of flood scenarios, revealing bridges at risk from flooding.
Now, the department can use this information to plan ahead for potential structural failures, impacts to evacuation routes, and impacts to emergency responder routes during storms.
