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.
“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.
I spent most of this day at MakerFaire hanging out at the Game of Drones encampment, but got the chance to wander around the main show area again.
I left early in the morning, arriving from my place in Palo Alto around 8:15 AM, and quickly learned one useful MakerFaire trick: the Franklin Templeton Investments outlet in San Mateo was offering free parking to attendees, only about a ten minute walk from the event grounds.
You might want to remember that tip for next year. Why Templeton did this — I can’t answer that one, although it’s certainly not often that I harbor kind thoughts about a global investment firm.
Game of Drones kicked off another long day of vicious aerial robot battles, which were eternally well-attended. I think they’re really onto something here, judging by the rapt fascination of both kids and adults who showed up to watch the action and the well-delivered calling. I could see this being a highly amusing new road-show — like Robot Wars but a lot speedier.
A true profusion of UAV makes and models competed in the action, but my favorite was definitely the Barbie Dream Drone, made by Edie Sellars. I think I need to make a My Little Pony themed model for next year.
The safety net proved to be the undoing of more drones today, although the pilots were getting better at avoiding it. On the plus side, the crowd goes nuts when a drone gets tangled in the netting. Also, turns out a PVC tube with a toy gripper claw operated by string works pretty well for getting the UAVs down.
The organizers of MakerFaire seemed to agree about the event: Game of Drones scored an Editors Choice award, which was presented in a delightfully country-fair analogue little blue ribbon. I wish them all the best. And hope to get my filthy paws on one of their Sumo quad airframes soon.
Turns out El Pulpo Mecanico gives the occasional show, with bursts of superheated flame coordinated to blippy electronic music. If you can’t get to Burning Man and are in fact opposed to spending $500+ to hang out with your parents and their friends while they drop endless quantities of acid, the sculptures here at MakerFaire may represent your next best bet. The El Pulpo operators occasionally give the flames full blast without warning, scaring the hell out of the spectators milling around the area. It’s very, very fun to watch.
Glassblowing, blacksmithing, jewelry and more by complements of The Crucible. I am fairly certain I’d end up covered in third degree burns if I tried to imitate my favorite Skryim character in real life, but I’m glad someone does it. They’ve got classes on offer if you want to take your faux video game skills into the real world, and make some sweet swords or something. Or spoons. You could also make spoons.
I managed to resist the urge to buy everything I wanted at MakerFaire, which would have been a hilariously expensive proposition, but this bronze giant squid necklace from Dragon’s Treasure was too awesome to resist. If you’re as fond of eccentric jewelry as me, you should check out their website immediately.
If you’ve spent any time at all around me in recent months, you are probably aware I’m really, really interested in UAVs — often called “drones.” I did a brief story on consumer-level UAV technology for school, realized how unfathomably cool they were, and joined the Stanford University UAV club.
Now, I own a Phantom 1 with a camera gimbal and am hoping to build my own. I’m also planning on going overseas with a couple of camera UAVs and putting them through their paces on the Southeast Asia correspondence beat. One way or another.
Now, you can help me out by filling out a survey I’ve put together for my digital entrepreneurship class at Stanford. I’m interested in figuring out a way to put together a NGO or a small business using UAVs to gather both images and data, and your input would be most helpful.
