Humanitarian UAVs Fly in China After Earthquake (updated)

A 6.1 magnitude earthquake struck Ludian County in Yunnan, China earlier this month. Some 600 people lost their lives; over 2,400 were injured and another 200,000 were forced to relocate. In terms of infrastructure damage, about 30,000 buildings were damaged and more than 12,000 homes collapsed. To rapidly search for survivors and assess this damage, responders in China turned to DJI’s office in Hong Kong. DJI is one of leading manufacturers of commercial UAVs in the world.

DJI’s team of pilots worked directly with the China Association for Disaster and Emergency Response Medicine (CADERM). According to DJI, “This was the first time [the country] used [UAVs] in its relief efforts and as a result many of the cooperating agencies and bodies working on site have approached us for training / using UAS technology in the future […].” DJI flew two types of quadcopters, the DJI S900 and DJI Phantom 2 Vision+ pictured below (respectively):

As mentioned here, The DJI Phantom 2 is the same one that the UN Office for the Coordination of Humanitarian Affairs (OCHA) is experimenting with:

Given the dense rubble and vegetation in the disaster affected region of Ludian County in China, ground surveys were particularly challenging to carry out. So UAVs provided disaster responders with an unimpeded bird’s eye view of the damage, helping them prioritize their search and rescue efforts. DJI reports that the UAVs “were able to relay images back to rescue workers, who used them to determine which roads needed to be cleared first and which areas of the rubble to search for possible survivors. […].”

The video above shows some striking aerial footage of the disaster damage. This is the not first time that UAVs have been used for search and rescue or road clearance operations. Transporting urgent supplies to disaster areas requires that roads be cleared as quickly as possible, which is why UAVs were used for this and other purposes after Typhoon Haiyan in the Philippines. In Ludian, “Aerial images captured by the team were [also] used by workers in the epicenter area […] where most of the traditional buildings in the area collapsed.”

DJI was not the only group to fly UAVs in response to the quake in Yunnan. The Chinese government itself deployed UAVs (days before DJI). As the Associated Press reported several weeks ago already, “A novel part of the Yunnan response was the use of drones to map and monitor a quake-formed lake that threatened to flood areas downstream. China has rapidly developed drone use in recent years, and they helped save time and money while providing highly reliable data, said Xu Xiaokun, an engineer with the army reserves.”

Working with UAV manufacturers directly may prove to be the preferred route for humanitarian organizations requiring access to aerial imagery following major disasters. At the same time, having the capacity and skills in-house to rapidly deploy these UAVs affords several advantages over the partnership model. So combining in-house capacity with a partnership model may ultimately be the way to go but this will depend heavily on the individual mandates and needs of humanitarian organizations.

The Humanitarian UAV Network (UAViators) is now live. Click here to access and join the network. Advisors include representatives from 3D Robotics, AirDroids, senseFly & DroneAdventures, OpenRelief, ShadowView Foundation, ICT4Peace Foundation, the United Nations and more. The website provides a unique set of resources, including the most comprehensive case study of humanitarian UAV deployments, a directory of organizations engaged in the humanitarian UAV space and a detailed list of references to keep track of ongoing research in this rapidly evolving area. All of these documents along with the network’s Code of Conduct—the only one of it’s kind—are easily accessible here.

UAViators 4 Teams

The UAViators website also includes 8 action-oriented Teams, four of which are displayed above. The Flight Team, for example, includes both new and highly experienced UAV pilots while the Imagery Team comprises members interested in imagery analysis. Other teams include the Camera, Legal and Policy Teams. In addition to this Team page, the site also has a dedicated Operations page to facilitate & coordinate safe and responsible UAV deployments in support of humanitarian efforts. In between deployments, the website’s Global Forum is a place where members share information about relevant news, events and more. One such event, for example, is the upcoming Drone/UAV Search & Rescue Challenge that UAViators is sponsoring.

When first announcing this initiative,  I duly noted that launching such a network will at first raise more questions than answers, but I welcome the challenge and believe that members of UAViators are well placed to facilitate the safe and responsible use of UAVs in a variety of humanitarian contexts.

Acknowledgements: Many thanks to colleagues and members of the Advisory Board who provided invaluable feedback and guidance in the lead-up to this launch. The Humanitarian UAV Network is result of collective vision and effort.

Grassroots UAVs for Disaster Response

I was recently introduced to a new initiative that seeks to empower grassroots communities to deploy their own low-cost xUAVs. The purpose of this initiative? To support locally-led disaster response efforts and in so doing transfer math, science and engineering skills to local communities. The “x” in xUAV refers to expendable. The initiative is a partnership between California State University (Long Beach), University of Hawaii, Embry Riddle, The Philippine Council for Industry, Energy & Emerging Technology Research & Development, Skyeye, Aklan State University and Ateneo de Manila University in the Philippines. The team is heading back to the Philippines next week for their second field mission. This blog post provides a short overview of the project’s approach and the results from their first mission, which took place during December 2013-February 2014.

xUAV1

The xUAV team is specifically interested in a new category of UAVs, those that are locally available, locally deployable, low-cost, expendable and extremely easy to use. Their first field mission to the Philippines focused on exploring the possibilities. The pictures above/below (click to enlarge) were kindly shared by the Filipinos engaged in the project—I am very grateful to them for allowing me to share these publicly. Please do not reproduce these pictures without their written permission, thank you.

xUAV2

I spoke at length with one of the xUAV team leads, Ted Ralston, who is heading back to the Philippines the second field mission. The purpose of this follow up visit is to shift the xUAV concept from experimental to deployable. One area that his students will be focusing on with the University of Manila is the development of a very user-friendly interface (using a low-cost tablet) to pilot the xUAVs so that local communities can simply tag way-points on a map that the xUAV will then automatically fly to. Indeed, this is where civilian UAVs are headed, full automation. A good example of this trend towards full automation is the new DroidPlanner 2.0 App just released by 3DRobotics. This free app provides powerful features to very easily plan autonomous flights. You can even create new flight plans on the fly and edit them onsite.

So the xUAV team will focus on developing software for automated take-off and landing as well as automated adjustments for wind conditions when the xUAV is airborne, etc. The software will also automatically adjust the xUAV’s flight parameters for any added payloads. Any captured imagery would then be made easily viewable via touch-screen directly from the low-cost tablet.

xUAV3

One of the team’s top priorities throughout this project is to transfer their skills to young Filipinos, given them hands on training in science, math and engineering. An equally important, related priority, is their focus on developing local partnerships with multiple partners. We’re familiar with ideas behind Public Participatory GIS (PPGIS) vis-a-vis the participatory use of geospatial information systems and technologies. The xUAV team seeks to extend this grassroots approach to Public Participatory UAVs.

xUAV4

I’m supporting this xUAV initiative in a number of ways and will be uploading the team’s UAV imagery (videos & still photos) from their upcoming field mission to MicroMappers for some internal testing. I’m particularly interested in user-generated (aerial) content that is raw and not pre-processed or stitched together, however. Why? Because I expect this type of imagery to grow in volume given the very rapid growth of the personal micro-UAV market. For more professionally produced and stitched-together aerial content, an ideal platform is Humanitarian OpenStreetMap’s Tasking Server, which is tried and tested for satellite imagery and which was recently used to trace processed UAV imagery of Tacloban.

I look forward to following the xUAV team’s efforts and hope to report on the outcome of their second field mission. The xUAV initiative fits very nicely with the goals of the Humanitarian UAV Network (UAViators). We’ll be learning a lot in the coming weeks and months from our colleagues in the Philippines.

Crisis Mapping without GPS Coordinates (Updated)

Update: Video introduction to What3Words:

I recently spoke with a UK start-up that is doing away with GPS coordinates even though their company focuses on geographic information and maps. The start-up, What3Words, has divided the globe into 57 trillion squares and given each of these 3-by-3 meter areas a unique three-word code. Goodbye long postal addresses and cryptic GPS coordinates. Hello planet.inches.most. The start-up also offers a service called OneWord, which allows you to customize a one-word name for any square. In addition, the company has expanded to other languages such as Spanish, Swedish and Russian. They’re now working on including Arabic, Chinese, Japanese and others by mid-January 2014. Meanwhile, their API lets anyone build new applications that tap their global map of 57 trillion squares.

When I spoke with CEO Chris Sheldrick, he noted that their very first users were emergency response organizations. One group in Australia, for example, is using What3Words as part of their SMS emergency service. “This will let people identify their homes with just three words, ensuring that emergency vehicles can find them as quickly as possible.” Such an approach provides greater accuracy, which is vital in rural areas. “Our ambulances have a terrible time with street addresses, particularly in The Bush.” Moreover, many places in the world have no addresses at all. So What3Words may also be useful for certain ICT4D projects in addition to crisis mapping. The real key to this service is simplicity, i.e., communicating three words over the phone, via SMS/Twitter or email is far easier (and less error prone) than dictating a postal address or a complicated set of GPS coordinates.

How else do you think this service could be used vis-à-vis disaster response?

Video: Humanitarian Response in 2025

I gave a talk on “The future of Humanitarian Response” at UN OCHA’s Global Humanitarian Policy Forum (#aid2025) in New York yesterday. More here for context. A similar version of the talk is available in the video presentation below.

Some of the discussions that ensued during the Forum were frustrating albeit an important reality check. Some policy makers still think that disaster response is about them and their international humanitarian organizations. They are still under the impression that aid does not arrive until they arrive. And yet, empirical research in the disaster literature points to the fact that the vast majority of survivals during disasters is the result of local agency, not external intervention.

In my talk (and video above), I note that local communities will increasingly become tech-enabled first responders, thus taking pressure off the international humanitarian system. These tech savvy local communities already exit. And they already respond to both “natural” (and manmade) disasters as noted in my talk vis-a-vis the information products produced by tech-savvy local Filipino groups. So my point about the rise of tech-enabled self-help was a more diplomatic way of conveying to traditional humanitarian groups that humanitarian response in 2025 will continue to happen with or without them; and perhaps increasingly without them.

This explains why I see OCHA’s Information Management (IM) Team increasingly taking on the role of “Information DJ”, mixing both formal and informal data sources for the purposes of both formal and informal humanitarian response. But OCHA will certainly not be the only DJ in town nor will they be invited to play at all “info events”. So the earlier they learn how to create relevant info mixes, the more likely they’ll still be DJ’ing in 2025.

How UAVs Are Making a Difference in Disaster Response

I visited the University of Torino in 2007 to speak with the team developing UAVs for the World Food Program. Since then, I’ve bought and tested two small UAVs of my own so I can use this new technology to capture aerial imagery during disasters; like the footage below from the Philippines.

UAVs, or drones, have a very strong military connotation for many of us. But so did space satellites before Google Earth brought satellite imagery into our homes and changed our perceptions of said technology. So it stands to reason that UAVs and aerial imagery will follow suit. This explains why I’m a proponent of the Drone Social Innovation Award, which seeks to promote the use of civilian drone technology for the benefit of humanity. I’m on the panel of judges for this award, which is why I reached out to DanOffice IT, a Swiss-based company that deployed two drones in response to Typhoon Yolanda in the Philippines. The drones in question are Huginn X1’s, which have a flight time of 25 minutes with a range of 2 kilometers and maximum altitude of 150 meters.

HUGINN X1

I recently spoke with one of the Huginn pilots who was in Tacloban. He flew the drone to survey shelter damage, identify blocked roads and search for bodies in the debris (using thermal imaging cameras mounted on the drone for the latter). The imagery captured also helped to identify appropriate locations to set up camp. When I asked the pilot whether he was surprised by anything during the operation, he noted that road-clearance support was not a use-case he had expected. I’ll be meeting with him in Switzerland in the next few weeks to test-fly a Huginn and explore possible partnerships.

I’d like to see closer collaboration between the Digital Humanitarian Network (DHN) and groups like DanOffice, for example. Providing DHN-member Humanitarian OpenStreetMap (HOTosm) with up-to-date aerial imagery during disasters would be a major win. This was the concept behind OpenAerialMap, which was first discussed back in 2007. While the initiative has yet to formally launch, PIX4D is a platform that “converts thousands of aerial images, taken by lightweight UAV or aircraft into geo-referenced 2D mosaics and 3D surface models and point clouds.”

Drone Adventures

This platform was used in Haiti with the above drones. The International Organization for Migration (IOM) partnered with Drone Adventures to map over 40 square kilometers of dense urban territory including several shantytowns in Port-au-Prince, which was “used to count the number of tents and organize a ‘door-to-door’ census of the population, the first step in identifying aid requirements and organizing more permanent infrastructure.” This approach could also be applied to IDP and refugee camps in the immediate aftermath of a sudden-onset disaster. All the data generated by Drone Adventures was made freely available through OpenStreetMap.

If you’re interested in giving “drones for social good” a try, I recommend looking at the DJI Phantom and the AR.Drone Parrot. These are priced between $300- $600, which beats the $50,000 price tag of the Huginn X1.

Humanitarian Response in 2025

I’ve been invited to give a “very provocative talk” on what humanitarian response will look like in 2025 for the annual Global Policy Forum organized by the UN Office for the Coordination of Humanitarian Affairs (OCHA) in New York. I first explored this question in early 2012 and my colleague Andrej Verity recently wrote up this intriguing piece on the topic, which I highly recommend; intriguing because he focuses a lot on the future of the pre-deployment process, which is often overlooked.

2025

I only have 7 minutes to give my talk so am thinking of leading with one or two of the following ideas−but I’m very interested in getting feedback from iRevolution readers and welcome additional ideas about what 2025 might look like for OCHA.

•  Situational Awareness: damage & needs assessments are instantaneous and 3D Crisis Maps are updated in real-time along with 3W’s information. Global communication networks are now hyper resilient, thus enabling uninterrupted communications after major disasters. More than 90% of the world’s population generates a readable, geo-referenced and multimedia digital footprint, which is used to augment 3D situational awareness; Fully 100% of all news media and citizen journalism content is now on the web and automatically translated & analyzed every second; high-resolution satellite and aerial imagery for 90% of the planet is updated and automatically analyzed every minute; Billions of physical sensors provide feedback loops on transportation, infrastructure, public health, weather-related and environmental dynamics in real-time. Big Data Analytics & advances in predictive modeling enables situational awareness to be predicted, allowing for IDP/refugee flows and disease outbreaks to be anticipated well ahead of any displacement.

•  Operational Response: disaster response is predominately driven by local communities. The real first responders, after all, have always been the disaster-affected communities. In 2025, this grassroots response is highly networked and hyper-tech enabled, thus significantly accelerating and improving the efficiency of self-help and mutual-aid. The Digital Humanitarian Network (DHN) is no longer a purely virtual network and has local chapters (with flocks of UAVs) in over 100 countries that each contribute to local response efforts. Meanwhile, close to 90% of the world’s population has an augmented-reality Personal Context Assistant (PCA), a wearable device that provides hyper-customized information (drawn in part from Quantified Self data) on urgent needs, available resources and logistics. National humanitarian response organizations have largely replaced the need for external assistance and coordination save for extreme events. International humanitarian organizations increasingly play a financial, certification and accountability role.

•  Early Recovery: There are more 3D printers than 2D printers in 2025. The former are extensively used for rapid reconstruction and post-disaster resilient development using local resources and materials. Mobile-money is automatically disbursed to enable this recovery based on personal insurance & real-time needs assessments. In addition, the Share Economy is truly global, which means that communication, transportation, accommodation and related local services are all readily available in the vast majority of urban areas. During disasters, Share Economy companies play an active role by offering free use of their platforms.

•  Data Access & Privacy: Telecommunications companies, satellite imagery firms and large technology & social media companies have all signed up to the International Data Philanthropy Charter, enabling them to share anonymized emergency data (albeit temporarily) that is directly relevant for humanitarian response. User-generated content is owned by the user who can limit the use of this data along the lines of the Open Paths model.

If you feel like this future is a little too rosy, that’s because I’m thinking of presenting two versions of the future, one that is optimistic and the other less so. The latter would be a world riddled with ad hoc decision-making based on very subjective damage & needs-assessments, highly restrictive data-sharing licenses and even the continued use of PDFs for data dissemination. This less-than pleasant world would also be plagued by data privacy, protection and security challenges. A new digital volunteer group called “Black Hat Humanitarians” rises to prominence and has little patience for humanitarian principles or codes of conduct. In this future world, digital data is collected and shared with no concern for informed consent. In addition, the vast majority of data relevant for saving lives in humanitarian crises remains highly proprietary. Meanwhile, open data that is publicly shared during disasters is used by tech-savvy criminals to further their own ends.

These two future worlds may be extremes but whether we lean towards one or the other will depend in part on enlightened leadership and policymaking. What do you think humanitarian response will look like in 2025? Where am I off and/or making unfounded assumptions? What aspects of the pictures I’m painting are more likely to become reality? What am I completely missing?

Update: Video of presentation available here.
