How Crisis Mapping Saved Lives in Haiti

To map the world, is to know it. To map the world live is to change it before it’s too late.

The National Geographic Society has a long history of crisis mapping disasters. But what happened in Haiti on January 12, 2010 would forever change the very concept of a crisis map. A devastating earthquake struck the country’s capital that Tuesday afternoon. I was overwhelmed with emotions when I heard the news just an hour later. Over 100,000 people were feared dead. Some very close friends of mine were doing research in Port-au-Prince at the time and I had no idea whether they had survived the earthquake. So I launched a live crisis map of Haiti. But this was an emotional reaction rather than a calculated plan with a detailed strategy. I was in shock and felt the need to do something, anything. It was only after midnight that I finally got an SMS reply from my friends. They had narrowly escaped a collapsing building. But many, many others were not near as lucky. I continued mapping.

Sourcing the Map

This is what the map looked liked after midnight on January 13th. What was I mapping exactly? Tweets. I had found a dozen Haitians tweeting live from Port-au-Prince shortly after the earthquake. They were describing scenes of devastation but also hope as this tweet shows:

I was using the Ushahidi platform, a free and open source mapping technology from Africa. Think of Ushahidi, which means “witness” in Swahili, as a multi-media inbox connected to a live map. I added these Twitter users to my inbox and began mapping the most urgent Tweets (those that had enough geographic information to be mapped). The following night, several friends joined me in the living room of my dorm to help map Haiti’s needs.

Volunteers to the Rescue

But within a couple days, we couldn’t keep up with the vast amount of information being reported via both social media and mainstream media. So I reached out to friends at The Fletcher School (Tufts University) where I was doing my PhD. By the end of the week, we had trained over 100 graduate and undergraduate students on how to monitor social and mainstream media for relevant, mappable content. These “digital humanitarians” began to manually monitor hundreds and hundreds of online sources for information on Haiti almost 24/7. The Ushahidi Haiti Crisis Map became a live map with some 2,000 individual reports added during the entire project.

Using Satellite Imagery

But mapping this content became more and more challenging because Port-au-Prince was half missing on the the Google Map of Haiti. The city and roads had not been fully mapped by Google Inc. So some colleagues at OpenStreetMap crowdsourced the most detailed roadmap of Haiti ever produced in just a matter of days. They used satellite imagery provided by the World Bank to carefully trace the road network onto an OpenStreetMap of Haiti. In fact, hundreds of volunteers from all around the world collaborated in these efforts. The following video is an animation of this tracing in action. Over 1.4 million edits/traces (flashes of light in the video) were made to the map in just a matter of weeks.

Crowdsourcing via SMS

Just hours after launching the crisis map, we also set up an international SMS number that members of the Haitian Diaspora could text important reports for us to map. The next day, my colleague Josh Nesbit from Medic Mobile started looking for local SMS options to support our Ushahidi Haiti Project:

Incredibly, someone following his Twitter feed in Cameroon put him in touch with a colleague who was working at Digicel, the largest telecommunications company in Haiti. Within days, we had secured a toll-free SMS number (4636) that allowed anyone in Haiti to text in their most urgent needs and location. This was made possible thanks to multiple groups: Thomson-Reuters Foundation, InSTEDD, US State Department and of course Digicel. In the days that followed, colleagues in Port-au-Prince got the word out about this SMS number by visiting several local community radio stations. They also explained that this was only an information service, not a humanitarian hotline.

Translating Needs

Soon enough, we began receiving thousands of text messages. As expected, these SMS’s were written in Haitian Creole rather than English. So my Ushahidi colleague Brian Herbert pulled an all-nighter to customize a web-based interface which was hosted at [no longer online]. The purpose of this second platform was to enable Haitian-Creole speaking volunteers to translate and geo-locate text messages sent to the SMS number. In effect, the platform was designed to enable the crowdsourced translation and geo-location of incoming text messages specifically for the Ushahidi Haiti Project. Many volunteers from the Haitian Diaspora joined the cause after hearing about the need for volunteers via Facebook.

Some Concerns

During this time, we contacted severals lawyers in Boston to determine whether we could even map these text messages from a privacy standpoint. They opined that we had implicit consent. Two seasoned humanitarian colleagues were also consulted for their feedback. They noted that Haiti was a particularly low risk situation. In other words, the possible harm that could come to local populations was minimal. Do No Harm is a standard principle for anyone operating in a humanitarian crisis or recovery context. The principle is important because it recognizes there is a risk to any intervention. And what is critical in deciding whether a certain course of action is ethical is to consider whether it could potentially cause harm to the local population. Given this feedback, we collectively decided that making the data open in this case was of minimal risk.

Meanwhile, back on the World Wide Web, several hundred volunteers logged on to Ushahidi’s translation platform and reportedly translated some 80,000 10,000 text messages during the first few weeks. Most of these, however, were either not relevant, actionable or mappable. So volunteers at The Fletcher School triaged the translated messages and only mapped the most important life and death messages, i.e., less than 2% of all SMS’s, a very small percentage indeed.

Engaging the Diaspora

Since a number of these SMS’s required more precise geo-location before they could be added to the map, we worked closely with many members of the Haitian Diaspora in Boston who obviously knew their country far better than any of us did. A number of our Haitian friends actually joined us (often for long hours on end) in our make-shift “Situation Room” at The Fletcher School (picture below).

Operational Response

On January 19th, just a week after the earthquake, someone from the US Coast Guard emailed us with the following question: “I am compiling reports from Haiti for the US Coast Guard and Joint Task Force Command Center. Is there someone I can speak with about how better to use the information in Ushahidi?” Several days later, we set up a dedicate Skype chat with the Coast Guard to fast-forward the most urgent (and actionable) content that was being added to the live Haiti Crisis Map. We were also contacted by an American Search and Rescue team in Port-au-Prince who urgently needed GPS coordinators for the locations of trapped individuals. More on this incredible story here.

On January 22nd, the US Marine Corps got in touch with us via email:

“I am with the US Marine Corps. I am stateside assisting the 22 MEU [Marine Expeditionary Unit] coming off the USS Bataan [on the Haitian Coast]. We want to use your data to bring aid to the people Haiti right now. The USMC is focusing on Leogane, Grand Goave, and Petit Goave. Is there a way to import your data into Google Earth or GIS? We want to make this work for the people of Haiti…please let me know ASAP”

Needless to say, we replied ASAP. On the same day, FEMA’s Administrator Craig Fugate,  shared the following on his Twitter feed:

Five days later, the same contact from the US Marine Corps shared the following by email (which we got permission to make public):

“I can not overemphasize to you what the work of the Ushahidi/Haiti has provided. It is saving lives every day. I wish I had time to document to you every example, but there are too many and our operation is moving too fast.  Here is one from the 22 MEU [Marine Expeditionary Unit]: ‘We had data on an area outside of Grand Goave needing help. Today, we sent an assessment team out there to validate their needs and everything checked out. While the team was out there, they found two old women and a young girl with serious injuries from the earthquake; one of the women had critical respiratory issues. They were evacuated.’

Your site saved these people’s lives. I say with confidence that there are 100s of these kind of stories. The Marine Corps is using your project every second of the day to get aid and assistance to the people that need it most. We did have a tech barrier that we had to surmount. The Marines downrange have Google Earth and your site does not work on the ship for them. So, I had Georgia Tech create a bridge from your site to Google Earth.

But it is YOUR data and YOUR work that is putting aid and assistance directly on the target and saving lives. Our big gap right now is locating NGOs and where they are working. Your site is helping with that. Keep up the good work!! You are making the biggest difference of anything I have seen out there in the open source world.”

At the end of this 2 month operation in Haiti, the Crisis Map looked like this:


These incredible efforts following the Haiti earthquake demonstrated a huge potential for the future of humanitarian response. Student volunteers in Boston working online with the Diaspora using free mapping technology from Africa could help save lives in another country thousands of miles away without ever setting foot in said country. In time, these reactive and organic volunteer-driven efforts in Haiti, and those that followed that same year in Chile, Pakistan and Russia, led to the launch of the award-winning Standby Volunteer Task Force (SBTF), a global network of 850+ volunteers in more than 80 countries around the world who use their live mapping skills to support humanitarian, human rights, development and media organizations .

The purpose of the SBTF is to create a network of already trained volunteers so we don’t have to scramble again like in Haiti. SBTF volunteers (or Mapsters as they are called) have since partnered with multiple organizations in dozens of deployments around the world.  The SBTF is now also part of the Digital Humanitarian Network (DHNetwork), a new consortium of volunteer networks who support humanitarian organizations.

For my next blog post in this series on Crisis Mapping, I’ll share an equally remarkable story about the United Nations, Genghis Khan, Satellite Imagery, Somalia and National Geographic. Yes, they’re all  connected in an intriguing way. Stay tuned to find out how! And remember, to map the world is to know it. But to map the world live is to change it before it’s too late.

    Patrick, to read this blog post after 2 1/2 years of having lived one of the most life altering experiences I’ve had is incredible. Thank you for having followed your emotional intuition and putting up Ushahidi/Haiti. It allowed a girl in her Montreal apartment to focus her Twitter addiction and put it to good use. You have an incredible heart.

    • Hi Rachelle! Sooo good to hear from you 🙂 Thanks so much for your very sweet note and for being an absolute rockstar during the Haiti response. Thanks for being you! One Map, One Love 🙂 Hugs!


    That crisis map is absolutely incredible! Thank you for sharing Patrick.

    • Thanks very much, Jared. As you can tell, this was a big big team effort.

  • Hannah

    Hi Patrick. Really great to see how techonology can be used to aid operational response from beginning to end. I work for an international NGO and we are trying to embed the use of crisis mapping (and other tools) in our teams. I would love to know if you are planning to present your case verbally to an audience? Or if you would consider it? Please let me know!

    • Hi Hannah, many thanks for your kind note. I’m a big fan of your organization’s work. National Geographic will be making the video of my 15 minute presentation on Haiti & Somalia public in the coming weeks, so perhaps that might be helpful? Several other videos of my presentations are available here:

      I do a fair bit of speaking on humanitarian technology, so would certainly be happy to present to an audience anytime. In other news, the Digital Humanitarian Network & Standby Volunteer Task Force have just been activated by UN OCHA for a project in South Sudan. If the these networks can also be of service to your organization then we can certainly explore this as well.

      Thanks again!

    Those doing humanitarian work in collaboration with the US military in Haiti should bear in mind the history of the US role in Haiti.

    The Coast Guard and Marines (to take those mentioned in this article) have been crucial to the US’s anti-democratic activity in Haiti, and to the blockading, interdiction, and mistreatment at Guantanamo of Haitian refugees.

    In the 1990s, there were reports of the US military’s mapping of Haiti for the purpose of tracking (and opposing) pro-democracy groups in the Haitian countryside.

    This “politics” has practical implications. We’ve heard about post-earthquake problems having to do with the US military’s controlling of the Port-au-Prince airport, reportedly delaying aid delivery until “security” was established — when in fact there was nothing like the kind of violence the military was conditioned to expect.

    This US military mindset is partly due, I assume, to the fact that the US military is not a humanitarian organization; but the specifics of US/Haiti policy over the years — including intentional disinformation — have to have played a key role.

    This was, of course, a crisis. But now that NGOs and others are in the lesson-learning phase, more awareness of our history might lead to recognition that oversight of military and non-military “authorities” on the ground is essential.

    Dear Patrick. Yes it was a great job and is nice to see that we are still using and developing new ways to help save lives using technologies. Starting with the Colombian earthquake drill in 2009, the SIMEX in 2010 (the first SBTF activation) to Crisis in Libya and Colombian floods, (and today the Syria crisis) there are a lot of good results on this work. But we still have a lot of task to do to have a real syncronization between humanitarian actors and volunteers/tech community. We must go beyond. Nice job. Saludos. Luis

  • Rebecca Schwartz

    Hi Patrick,

    I would like to speak with you about this project. Is there a way that I can connect with you to discuss? A little about me, I am a graduate student at NYU who will be doing my graduate thesis on the role/response of the Haitian diaspora post the 2010 earthquake. I am currently taking a class dealing with crisis mapping and after conducting some research came across this blog! VERY interesting stuff that I would like to incorporate in my thesis. I look forward to hearing from you.


    • Hi Rebecca, thanks for your kind note. I’ll send you an email pronto.

      All the best,

  • Tajjammul Hussain

    Hi Patrick,

    Interesting piece of work…would be great if you could help with he following :

    1. How did we get the coordinates – did we use the tweets or text messages to get exact coordinates of the sender or did we use names/place/landmarks in a given report to determine approx. coordinates ( of course withe the help of the Diaspora)

    (2) Referring to the “Do No Harm principle” where the rationale that when deciding whether a certain course of action is ethical is to consider “whether it could potentially cause harm to the local population” makes absolute sense, however for the sake positive critique, if we assume some truth in the feedback from “Mark Dow” above – wouldn’t there be a potential for security risk both at a political level and locally (because crisis nodes can be good targets for social nuisance elements)..I may be exaggerating given the criticality of the situation when the exercise was done, but I think its worth a question being considered…


    • Hi Tajjammul, thanks for your kind note.

      1. We used names, places and landmarks in tweets, text messages, etc to find the approximate coordinates. The OpenStreetMap of Haiti was particularly useful for this as were members of the Haitian Diaspora in Boston and beyond.

      2. As per the “Do No Harm” principle, there is a risk to all humanitarian interventions. There are no risk-free interventions. The point of “Do No Harm” is to weight the risks against the expected gains.

      All the best,

    “Res i Sista minuten” I think you are right that the story is good but you shouldn’t agree.

    The story is taken from the same format that was in the article about how Ted talks are lies:
    It’s all about someone portraying themselves as the “accidental hero”
    I would expect National Geographic to be smart enough to see through this.

    The details are taken from people like me:
    Haitians who helped with crowdsourcing after the earthquake.

    It looks like the author took the details from Mission 4636, a Haitian-led response to the earthquake. I know some of the people who ran this. Every decision about publicity and media is voted on by a group of Haitians who ran these response efforts. I am very surprised that they gave permission for National Geographic to use their stories in this way.
