In disaster's wake, novel computing techniques support emergency responders

To assist FEMA with the Carr Fire emergency response in California, ORNL researchers used satellite images and novel computing techniques to rapidly identify and deliver data of nearly 97,000 potentially impacted or vulnerable homes and buildings in Shasta and Trinity counties. ORNL fulfilled FEMA's request in just two days, a task that could take several weeks with conventional methods. Credit: Melanie Laverdiere/Oak Ridge National Laboratory, US Dept. of Energy.3 Oct 2018 Oak Ridge - As hurricanes barrel toward the coastlines and wildfires rage in arid regions of the United States, scientists at the Department of Energy's Oak Ridge National Laboratory are providing critical geospatial data to support first responders as they work to save lives and property.

When disasters strike, many homes and buildings succumb to winds, floods or flames. To assist humanitarian and damage assessment efforts, Oak Ridge National Laboratory (ORNL) researchers are using novel computing techniques to rapidly identify structures on the ground from satellite images or determine where the structures once stood.

Behind the scenes, the geographic information team digitally sifts through thousands of images and collects meaningful data in a matter of hours, a process that previously would take several months.

"When you look at imagery such as what's shown in Google Maps, it's very easy to visually distinguish what is a building and what is not", stated Melanie Laverdiere, a geographic information system scientist at ORNL. "However, extracting this meaningful information in an automated fashion into a tangible data set is much more complex."

Melanie Laverdiere works with ORNL project team lead Mark Tuttle and colleagues who are actively supporting the Federal Emergency Management Agency, or FEMA, with information on buildings and structures in a hurricane's path, and those that remain in harm's way. Their technique was also applied for California's Shasta and Trinity counties, both affected by the recent Carr Fire.

The team collects large sets of data that identify and characterize hundreds of vulnerable and affected structures, such as residences, businesses, schools and hospitals. This information proves critical to FEMA - the agency responsible for directing emergency response and assessing damages after an emergency event to inform recovery operations.

ORNL researchers first tested their approach in 2017 during the emergency response to Hurricane Harvey that hit Texas hard with flooding, and hurricanes Irma and Maria that devastated Puerto Rico and impacted parts of Florida and the Caribbean. In 2018, the ORNL team was called upon to assist with damage assessments from destructive lava flows in Hawaii.

"During devastating weather and geological events, it is a time-consuming task to assess damage, a process that requires personnel in the field. However, our data permits responders to focus field efforts on areas most likely to have sustained damage", Mark Tuttle stated.

"Our method supports emergency response efforts by providing preliminary building structure data - which can be categorized for residential, multifamily and commercial properties - on the county level", he added.

This approach was applied to hurricane-impacted areas of Texas, Florida, Puerto Rico and the U.S. Virgin Islands and other U.S. Caribbean territories.

During Hurricane Harvey, ORNL analyzed nearly 2,000 images covering nearly 26,000 square miles of building structures in Texas' coastal counties in just 24 hours, a process that would typically take up to nine months.

In support of emergency response to lava flows, Mark Tuttle's team processed data focused near Kilauea, Hawaii, in less than a day and all visible structures on the entire Island of Hawaii in only two weeks.

The geospatial scientists who work with Mark Tuttle include Melanie Laverdiere, Taylor Hauser, Hsiuhan Yang, Jake McKee and Matthew Whitehead, with collaboration from the lab's Urban Dynamics Institute.

This work is sponsored by the Federal Emergency Management Agency.
