The right way to map a forest by way of drone — as proven by world’s largest tree
Ever needed to see world’s largest tree — by drone, no much less? Some drone pilots took to photographing the large, pure marvel for fairly a sensible purpose.
The tree, dubbed Basic Sherman, sits inside California’s Sequoia Nationwide Park. And in Might 2024, the U.S. Nationwide Park Service — in a partnership with teams together with the Large Sequoia Lands Coalition — commissioned a drone flight to conduct a first-of-its-kind well being check-up for the tree.
Basic Sherman stands 275 toes tall and greater than an estimated 2,200 years outdated.
With that challenge, an Freefly Astro Prime drone flew over the cover. Throughout its flights, the drone carried a variety of various sensors similar to a lidar payload to detect modifications within the cover.
The well being check-up comes at a important time for analysis of the beloved big sequoias. An estimated 20% of the world’s big sequoias have been misplaced within the final 4 years alone. That’s due largely to California’s wildfires. However that’s not all. A species of beetle has additionally been invading the timber, inflicting whole timber to die.
This drone inspection had a reasonably joyful ending. Whereas researchers used the drone information to detect some extent of native bark beetle exercise, researchers concluded that it wasn’t a regarding quantity.
“Drones give us a capability to scale out these observations,” mentioned Sam Prentice, a soil scientist and drone specialist with the Forest Service.

The right way to monitor forest well being by way of drone
No, this challenge was not so simple as simply flying an affordable digital camera drone over a tree to test it out. In spite of everything, these beetles are tiny, and their impacts typically aren’t even seen with the bare eye. On condition that, a extra superior drone carrying a payload smarter than a fundamental digital camera got here into the image.
Drone used: For this challenge, pilots used Freefly’s Astro Prime drone. The Astro Prime is a comparatively new model of the unique workhorse business UAS platform from Freefly. The Astro Prime is NDAA-compliant and Blue UAS-approved.
Payloads used: The drone was mounted with numerous swappable payloads, together with a Lidar scanner and HD video digital camera.
Communication system used: From there, the drone known as on mesh rider radios from Doodle Labs. The mesh rider radios set up a resilient datalink, keep connectivity and full management of the drone in an off-grid atmosphere. That permits them to reliably ship high-bandwidth information again to the bottom.
Get Nationwide Park approval
In case you’re planning to map a forest inside a Nationwide Park, know that you simply’ll want approval. Drone use is often banned in Nationwide Parks beneath 36 CFR 1.5. That rule prohibits launching, touchdown, or working drones on lands and waters administered by the Nationwide Park Service (NPS) NPS.
To conduct aerial mapping missions, researchers must receive particular permits from the NPS. You may normally examine with the park superintendent to see if an space could be designated throughout the park. They’ll define get a particular use allow if essential.
Violation of the ban is a misdemeanor with the utmost penalty of six months in jail and a $5,000 wonderful.
What this challenge indicators to be used of drones in environmental science
“The capabilities of the Astro prime and its NDAA-compliant standing will allow the U.S. Forest Service and different Division of Inside teams to name on the platform for continued use in land mapping and inspection a lot sooner than older handbook processes,” in accordance with a press release from Doodle Labs.
It’s additionally compelling to see the actual selection by the U.S. Forest Service to make use of a Freefly drone. Freefly is an American drone firm. Its merchandise are designed, assembled, examined, and supported by the Freefly workforce at its headquarters in Woodinville, Washington. Freefly merchandise are additionally far costlier than a DJI drone. The Freefly Astro Prime Drone with a Sony ILX-LR1 digital camera prices a hefty $27,000.
However the U.S. authorities’s choice to make the most of the American-made Freefly drones for aerial mapping could be seen as a sign of rising curiosity in supporting home drone producers like Freefly over their Chinese language counterparts, DJI. Just lately, politicians have raised considerations concerning potential safety dangers related to Chinese language-made drones. Whereas Freefly drones could not possess the identical widespread model recognition as DJI, this challenge signifies a possible shift.
