Last week, Hurricane Irma hit the southern United States coast, and while there was little that could be done to lessen her impact, Airmen from the 118th Wing utilized their skills in geospatial imagery analysis, and experience in working previous natural disasters, to provide damage assessment products to first responders on the ground, and therefore quicken the recovery process.
“[We] first started in Puerto Rico, and moved to a small island outside of Puerto Rico, and did a lot of damage assessments there,” said Master Sgt. Lauren, a member of the 118th Wing. “And then we moved to Florida, it keeps growing each day.”
“The way things are now a days with technology, there’s not really a friction of distance or time,” said Capt. Charles, a member of the 118th Wing. “We can create a product, upload it to a common portal they have access to and they can get it pretty quick as well.”
The process in which the Airmen create the damage assessment products requires going through numerous satellite pictures of the area from multiple agencies.
“Basically we look at the first image, pre-disaster imagery, and then we look at the home or whatever we are trying to analyze,” said Lauren. “Then we compare it to the post-disaster imagery we are receiving daily.”
“We’ve had Civil Air Patrol imagery, imagery from the National Oceanic and Atmospheric Agency, as well as from NASA,” said Charles. “USGS [United States Geological Survey] has been another big source as well.”
From the images, the 118th Airmen are able to identify a variety of damage inflicted by the hurricane.
“Mainly [we see] wind damage, a lot of blown debris, collapsed structures; and every now and then, depending on when the image was shot, you’ll see flooding,” said Charles. “We can also see if anything leaks, if there are materials or substances that are unnatural that leak into natural waterways.”
The 118th Airmen have already created over 100 damage assessment products from the imagery for ground crews to use, said Lauren.
With the birds-eye view and analysis the Airmen are able to provide, it provides essential advice to the first responders on the ground.
“FEMA [Federal Emergency Management Agency] has been getting back with us saying it’s really helpful,” said Lauren. “It’s going to speed up their reach out to these people who’ve lost their homes.”
“The feedback we’ve gotten is that they’ve incorporated a lot of the stuff we have produced, and it’s helped make their job easier,” said Charles. “Being able to provide them some of those situational awareness products, and say ‘Hey don’t worry so much about this area, this area is a little more impacted,’ again helps drive their decision making process.”
