Case study

Wetlands are the superheroes of storm damage prevention—here’s how MAP61 is helping them stay strong

According to NOAA, as of November 1, 2024, the US saw 24 confirmed natural disasters, each exceeding 1 billion USD in damages. For context, the 1980–2023 annual average was 8.5 events. But there’s a bright side to this story if we take action: Wetlands and wetland monitoring helps reduce the damage of these more frequent natural disasters significantly. And drone data—based on the latest technology—helps professionals do that more efficiently than ever before.

Challenges

Billions of dollars a year could be saved if wetlands are conserved restored as buffer zones between the brunt of storms and nearby residential areas. So land owners are now compensated to manage them. Surveying huge, inaccessible areas is hard to do efficiently.

Solutions

Drone data is key to getting these areas documented, starting with high-accuracy and high-resolution baseline conditions. In cases where wetlands are being used as preventative mitigation banks, Wingtra data is useful to monitor species composition and health.

Army Corps Geographer and assistant professor at VCU’s Rice River Center, Will Shuart describes why payload quality matters to the final survey product. He particularly emphasizes mechanical shutter tech and drone flight stability as factors that improve your drone survey outcomes, especially when trees are involved. 

An invaluable survey tool

Shuart has been working with Wingtra for several years. He’s mapped with every payload the drone can carry. And he’s provided a range of valuable data to various projects, including wetland survey data for carbon credits and billions of dollars of storm prevention.

The Wingtra difference for wetlands mapping

U Challenge

Big, inaccessible areas

Wetlands are large zones, inaccessible on foot—so a drone needs to fly from a take-off point to the capture area and back.

m Solution

Wingtra VTOL and efficiency

Wingtra’s VTOL enables take-off and landing  from compact  points, while its fixed-wing flight enables huge areas covered per flight.

U Challenge

Tight wetland flight windows

Tides and precipitation can reduce the windows of data capture time and make it hard to predict when it’s even possible

m Solution

Easy setup and fast capture

Wingtra constantly upgrades from the best-in-class cameras by Sony, which offer high res, sharp imagery.

U Challenge

High detail

It’s one thing to cover large areas, but tree counts and details are important to monitor for carbon credits, and this requires detail.
m Solution

MAP61 oblique configuration

MAP61 is equipped with a wide-angle lens and sits at an oblique configuration to capture rich vertical and horizontal detail.
U Challenge

Getting good baseline data

Base maps of wetlands are are baselines for measuring changes over time and must be accurate.
m Solution

Efficient surveys

WingtraOne GEN II captures reliable baseline data to monitor not only growth and expansion, but also erosion and tide cycles.

 I’ll get a tide forecast and it could say it’s going to be low tide at 3:30 in the afternoon. Sometimes it doesn’t really happen until 4:15 or 4:30 or 4:45. So I can literally stand right here, and I can say, ‘yeah, I think that’s the absolute low tide. Let’s send the drone up and map.’ With Wingtra, you can count on it at the moment that you need it.

Will Shuart has been flying Wingtra for years and has every Wingtra payload. Wingtra RGB payloads in particular are founded in leading-edge Sony cameras.

These cameras offer premium optics and speed that promotes sharp imagery. Shuart’s experience offers a glimpse of the trade-offs across payloads in terms of coverage, accuracy, image weight and flight time. He’s especially excited about MAP61 since it grabs fine details in 3D for tree counts.

Accuracy reports are a full, in-depth testament to the quality of the optics of any payload. Check these example reports Shuart provided for a look at the real accuracy achieved.

Wingtra LIDAR for wetlands mapping

Adding Wingtra LIDAR data to the analytics brings a new level of analytics as classification of the data enhances tree counts and also helps monitor terrain. For this video, Shuart flew at  200 ft (61 m) AGL for a point density of about 80 ppm.
