I’ve been watching the rise of China’s DJI consumer drone company for over a decade, ever since DJI launched the cheap drone epoch we’re living in today with the release of the original Phantom back in 2013. The Phantom was revolutionary, the first drone that pretty much anyone could use to shoot sweet footage of surfers – a device that launched an entire industry of drone service providers, and turned the Shenzen based company into, arguably, China’s closest answer to Apple.
At the same time, the United States and other countries have grown increasingly suspicious of DJI’s motives and loyalties, and lawmakers, like the odious Ron DeSantis in Florida, are rolling out new policies that crack down on the use of Chinese-made drones by government employees, from police officers to state university researchers.
Which might seem kinda reasonable, as compared to the other things DeSantis gets up to, except there’s one big, fat problem: there is no non-Chinese consumer drone company that does what DJI does. Much less does it at such a low price-point, which is a vital consideration for the vast swaths of modern drone users who don’t have unlimited cash to throw around.
And building a DJI-killer is a lot harder than you might assume: although a number of Western competitors tried to knock DJI off the pedestal over the last decade, they all failed. Partially, this was because DJI’s Shenzen location gives it direct access to the world’s biggest source of electronic parts manufacturing. Partially, a lot of those Western consumer drone companies made some really dumb decisions. Eventually, they largely stopped trying.
This is also why both Ukrainians and Russians are continuing to chew through vast quantities of DJI drones on the battlefield, despite massive misgivings about their reliance on Chinese tech. While Russian leaders may regularly claim that they’ll be coming out with a DJI replacement any day now, I’m not exactly holding my breath.
What’s more, our uncomfortable dependence on DJI creates a pretty enormous problem for civilian drone users in every country that doesn’t get along with China. If DJI drones were suddenly banned in one fell swoop in the US tomorrow, as some GOP lawmakers are calling for, then the civilian drone industry would be, to put it delicately, completely screwed.
I believe that it’s possible for the US and Europe to figure out how to build drones that can actually compete with DJI products, but it’s going to take some government support and changing up some of our existing priorities. Anyway, read the full Foreign Policy story here.
I wrote for Foreign Policy about how consumer drones are much better at terrifying people than they are at killing them – and why it is important that we recognize this.Read it here.
“The camera shook with the sound of an explosion and Venezuelan President Nicolás Maduro looked up, confused. Guards swiftly surrounded him with protective shields; soldiers in the military parade he was addressing scattered for cover. So did everyone else around him, reacting to the sound of a nearby explosion from the sky. Maduro and the Venezuelan government say—and video evidence seems to confirm—that someone tried to attack him with an explosives-laden consumer drone, likely made by Chinese drone manufacturer DJI. Open-source reporting organization Bellingcat and other investigative outlets agree that the attack involved drones, despite early reports claiming otherwise.
There have been fears for years that commercial drones would be turned into deadly weapons. But was this their coming-out party, the incident where death-by-drone moves from the military into the hands of terrorists and assassins? I don’t think so. Neither does European Council on Foreign Relations policy fellow Ulrike Franke, who told me: “To put it bluntly, I don’t think that this was the event that changes the view of smaller commercial drones from good to bad.”
We’ll be covering the basics of satellite and drone technology, as well as data collection and platforms, ethics and legal issues in remote sensing, and more. While the course is geared towards humanitarian professionals and managers, I suspect many people with an interest in remote sensing will find it informative and interesting.
The course will be held on the Harvard campus, and lunch and breakfast will be covered.
You can register online, though feel free to get in touch with me independently if you have any specific questions. And, share with your friends.
I’ve been messing around a lot with Adobe Illustrator. It’s an incredibly irritating piece of software if you’ve grown up using nothing but Adobe Photoshop – everything is counter-intuitive! What does that symbol even mean? Why can’t I just combine the two things, why is this so hard! But I’ve passed over some kind of learning curve and am now having a lot of fun with it. It’s a very different method of drawing and making illustrations than hand-drawing stuff, but it allows allows me to try some new things.
So. In Illustrator, I made a lot of holiday-themed pictures of drones. I’m thinking of selling whimsical drone stickers on an Etsy account, or something. I still need to figure out if I’d be able to at least break even.
Have some drone holiday cheer.
You have no idea how difficult drawing Santa was in Illustrator. My resentment for Santa has mostly passed but it was touch and go there for a while.
I think this Inspire is actually kind of fetching with the hat, but my aesthetic is weird.
In the arena of art that doesn’t somehow involve a flying yet benign robot, I drew some animals who aren’t enjoying the holidays. Holiday ennui knows no species.
“Imagine for a moment that you are a person who owns a falcon. You don’t own the falcon just to have an unusual and intimidating pet but because you are a licensed falconer, among the growing ranks of Americans dedicated to the ancient and complex art of training birds of prey to hunt in partnership with humans. As part of your falcon’s schooling process, you must teach her to fly high, high enough to scan for prey and gain enough altitude to speedily swoop down on a smaller animal—and this is a challenging task, especially if you are a human being who is stuck on the ground. An increasing number of falconers around the world are solving this ancient logistical problem with a decidedly modern tool: a drone.”
I decided to read “H is for Hawk” as I was writing this piece, which did indeed provide me with some interesting insight into how falconry works, but also was the most enjoyable reading experience I’ve had this year. On one level, it is a great exercise in writing about a esoteric or technical topic in a way that is not even a little dry. Helen MacDonald writes like an old kind of writer, I guess, which is inadequate but the only way I can put it. It was not surprising then that she had so much affection for E.B. White.
I’ve also had a long weird relationship with White’s writing, but also a kind of profound one. “The Once and Future King,” naturally – a book that actually can grow with you, one I’ll likely end up reading every five years or so until I’m dead. The book I read when I was 8 is not the same as the one I read at 17, and then it meant the most of all at 22. MacDonald captures with her simultaneous grief over her father and the agonizing and bizarre process of hawk-training what White means – this bizarre, eccentric man who so well conveyed emotional pain, uncertainty, fear.
The FAA has decided that drone registration may be its best bet for making sure drones don’t become a national nuisance after the Christmas gift-buying rush. But will it really work? And does it take into account DIY drones? I’m skeptical. You can read my take at Slate.
“It’s all the drone world can talk about: The Federal Aviation Administration announced Monday that all drones—not just those used for commercial purposes—would soon have to be registered, with the hope of providing a way to link badly behaved drones to their pilots. The new system, FAA representatives (optimistically) said, is hoped to be in placed by mid-December, to anticipate the hordes of underage children and overconfident dads expected to get drones for Christmas. There are lots of potential problems with this plan, which other experts have admirably described. But I want to focus on one particular obstacle. What should the FAA do about registering DIY drones—the flying objects that people make in their garages, instead of running out and buying?”
I recently bought a Phantom 3 Professional, operating under the logic that it costs $1200 and is therefore much more economical than a hexacopter. Myself and my partner, Daniel, are working on developing expertise in 3D mapping with a UAV, and I’d been looking for a new model capable of waypoint navigation and shooting high-quality, undistorted still images. My Phantom 2 still worked great, but it wasn’t great for mapping – built to use a fish-eye lens GoPro camera, and unable to carry out waypoint navigation without extra, expensive parts.
I was really sold on buying a Phantom 3 Pro after I visited the DroneDeploy offices in San Francisco and watched a demo of their waypoint navigation software, which is paired with their cloud computing processing. You fire up your mobile phone or tablet, sync it with the Phantom 3, then draw a box around the area you want to map. The software calculates how many times the Phantom will need to cross the area, the altitude of the area, and how many pictures are required, then you press a button. The Phantom proceeds to launch itself and carry out its work without your input, though you can always call it back from the controller. Simplicity. I like it.
So, I bought a Phantom 3 Pro— and since I live in the giant no-fly-zone otherwise known as Washington DC, I had it shipped to Daniel in Boston where I regularly visit him. On my last visit in early September, we decided to test out DroneDeploy and the Phantom 3 by using it to map the abandoned Medfield State Hospital in Medfield, Massachusetts, which I’d found out about on Atlas Obscura. (Scenes from “Shutter Island” were filmed there). Unlike most creepy, abandoned mental hospitals, this one had been opened to the community for use as a park, while the town decides how best to redevelop it. It’s a sprawling complex with red brick architecture and lush greenery around it in summer, with the Charles River bending towards one corner.
We parked across the street and walked in, and identified a parking lot where we could easily launch the drone from a flat location. DroneDeploy synced up easily enough with my Phantom 3, and I chose to map about half of the area, going conservative for a fist-time experiment. I pressed the button. It worked great: the Phantom efficiently flew off in the designated pattern, in neater lines then I could manage myself. It retuned to home in about 15 minutes, and landed itself, albeit with more force then I’d like. I may, in the future, switch back on manual control of the Phantom as it comes in to land after a DroneDeploy mission, as I prefer to catch it rather than landing it.
Since DroneDeploy missions currently can’t be flown with the camera at an oblique angle, I manually shot my own oblique imagery, with the Phantom 3 camera set to shoot images every five seconds. I flew reverse transects from the DroneDeploy pattern, and – following advice from DJI’s Eric Cheng – flew the drone in large, slow circles over the area I want to map. I probably should have worked with alternating the altitude more, but I was pleased enough with the images I was able to collect. The Phantom 3 handles even more smoothly than the Phantom 2, and shoots beautifully crisp still images with its 12-megapixel camera, without the distortion that used to annoy me with the GoPro.
We used both DroneDeploy’s processing tool and Agisoft Photoscan 3D to process the final imagery. Daniel has a great summary of the pros and cons of each over at his blog, so I won’t recap them – but in summary, DroneDeploy was a lot faster, while Agisoft PhotoScan had higher quality results but took a longer time and required much more processing power, and also required us to manually fill in some holes in the mesh.
Here is the final, orthorectified map. DroneDeploy’s ability to quickly orthorectify 2D maps using cloud processing is definitely handy. In the 3D model, DroneDeploy was not able to incorporate our oblique imagery successfully, although we’ve been in touch about the problem, and they’ve told us it will be fixed. There’s two other problems with DroneDeploy as of this writing: it only works with Android phones and tablets, and it requires either Wifi access or mobile data to function.
Both features are in the works, but keep this in mind if you want to experiment with it.In Agisoft Photoscan, which did use our oblique imagery, the sides of the model weren’t as detailed as we’d like – though, some of this is to be expected when mapping an entire complex of buildings. We could probably fix this by taking the time to shoot oblique imagery around each individual building, but this would take quite a bit of extra time and battery power. (I’d like to try it anyway).
Overall, I’m very pleased with the Phantom 3 Professional as an inexpensive mapping tool, and I’m excited to see what we can come up with next. I’m also interested in doing more work with DroneDeploy – and I eagerly await the release of the off-line version, which should make it a much more viable tool for field work. What else could we map in the area around Boston?
We’ve finally done it: the “Drones and Aerial Observation” primer I’ve been working on for New America with support from the Omidyar Network and Humanity United has been released into the wild. Ever wondered how drones can help with peaceful endeavors, from disaster response, to conservation, to archaeology? We have you covered.
With this book, I’m of the mind that myself, my colleague Konstantin Kakaes, and the drone experts who contributed chapters have created an overview of drone technology accessible to people who don’t already know what a “gimbal” is. (Yes, I am aware that is a funny word).
We hope the book will encourage people to start thinking of drones as a tech they can practically use for their own field endeavors. While drones certainly look complicated when you first encounter them – at least, that’s how I felt about them – it’s a tech that’s remarkably accessible to people who don’t have aeronautical engineering PHDs.
On my end, I wrote chapters 4 and 5: “How to Make Maps with Drones” and “Mapping in Practice.” Writing these chapters was a real crash-course in drone mapping for me, and I’m grateful to come out the other side alive and with a better sense of what’s required to carry out mapping projects. I hope I can pass that on to you. I’m also planning to get my own mapping drone in the very near future so I can start carrying out some of this work myself.
I also wrote Chapter 9, which is a case study of the world’s largest archaeological drone mapping project, carried out by the Ministry of Culture in Peru. They were incredibly hospitable to me, and I had a great time watching the researchers deal with the quotidian, difficult, occasionally terrifying realities of making maps with drones in remote and difficult areas. Many thanks to Aldo Watanave and Dr. Luis Jaime Castillo Butters for taking me along for the ride. A Slate piece about this work is impending as well.
My latest on Future Tense, documenting how inexpensive UAVs can help indigenous people (and other people without much access to resources) document where they live and what they own. From an interview with Irendra Radjawali, a fascinating Indonesian geographer who begun pioneering this kind of work with the Dayaks of Borneo, with some inroads into Papua and Bali. It’s really cool stuff.
I think this is going to be a particularly important usage of drones, and I hope to do more writing and research on that potential in the near future.
