Pericay, Martí
How to build a map website in one afternoon? How to get 1 million visits in less than 24 hours? How to technically survive to an unexpectedly high traffic without spending a huge amount of money? A story about a small GIS company that developed a website that helped millions in a very difficult moment. A tale of collaboration, generosity, open source software and luck. The ‘Keep it simple’ motto to the highest extent. Starring Geomatico, Mapbox, COVID-19, Github, Amazon, Alejandro Sanz and Nicolás Maduro. On March the 23rd, after five weeks of COVID-19 lockdown, president Sanchez announced that Spain will begin easing restrictions. In this first attempt at loosening measures across the country, children under the age of 14 would be allowed to go outside of their homes for one hour a day, accompanied by an adult. The measure limits travel to no further than 1 kilometer from home. But just how far is 1 kilometer? To help navigate these new rules, Geomatico, a Spanish GIS company, developed a non-profit web application using Open Source tools and donated services from Mapbox that allows adults and children to visualize a 1 kilometer radius around their home. In ten days, 1km.geomatico.es became a reference for individuals and families throughout Spain looking to safely leave their house for the first time in over a month. Thanks in part to Mapbox’s support, the team has been able to deliver this mapping service for free to over 7 million users in multiple languages.
 Okay, thank you. Welcome again. This is going to be the last talk on this session in Puerto Madri. Now we have Martí, Martí Periquei from Geomático. He's a GIS developer and analyst. In 2015 he joined Geomático to work on web development and training in open source special technologies. He's going to talk about a different corona, this time the one you know about, unfortunately. So very interesting to learn more about this going viral in the pandemic. You want to share your screen? Okay. Yes. Thank you, Jorge. So my name is Martí Periquei from Geomático. Our sponsors are funds, our city also are in the room also. I'll do the talk, but he might answer some questions later. Okay, so thank you all for being here. Geomático is a small Spanish company specialized in analysis and publication of geographic information. And we usually make technical talks. So this will be totally a new experience for us. It's more a light speech about a beautiful adventure or a tale of success in the pandemic. So perfect for the last beach before lunch. We have always worked with a traditional GIS stack, our players, geo server, post GIS, SDIs, now of course vector tiles also. And we've developed solutions for many years in many fields. Here I just highlighted mobility and environmental, but there are many more agriculture, public transportation, harbors and satellite analysis also. And to finish for a fast presentation of who we are, at least of some of our clients, a majority from Spain, but some from Europe or Australia. And what do we do for them? We call it tailored suits, like we offer custom solutions to complex geographical problems that don't fit into a standard product. That's what we generally do. Okay, so let's start with the tale. Let's start with the adventure. Let's make a flashback to April 2020. I think you all remember. In Spain, it was a complete lockdown. There were times you were only allowed to go to buy food, to go outside to buy food for emergencies. Well, you know about that. And we all look like this in our homes, except that we always look like this in Geomatica, because we work remotely since long time ago. But those were times of fear and of stress, but also of great solidarity and good intention, like everybody wanted to help others. So what can we do to help? There were already many projects, some of them very popular. I remember those charts for the countries, for dead people, infected people. And Italy's first, now Spain's first, a bit tragic, but they were useful. Or ambitious projects like a friend of mine did a project to detect COVID-19 and the excrement of people from the water collected in the sewers to try to prevent outbreaks. So what can we do from Geomatica? Let's think about something. Spain had a very painful first wave. Many people were not allowed even to make sport, and kids were getting crazy. And parents with kids were getting crazy. So after almost two months of lockdown, the government decided that they were allowed outside with adults, but only one kilometer away from their homes. So big happiness for everyone, but of course, how far is one kilometer? The average person can calculate that. That's a GIS question, a very simple one, but a GIS question. So many GIS friends were already calculating their kilometer. They took a QG, it's a buffer of one kilometer, and they printed their map, whatever. But what can we do for people, not GIS experts? Well, in Geomatica, the same day the new law was announced, Micho Garcia had the idea to build a website and to call it simply, how far is one kilometer to solve this problem? Okay, so how to build it? The challenge is to show a one kilometer circle, shouldn't be a big deal. Usually we develop advanced solutions, so we thought about some complicated applications, but in the end it was clear that we needed something very simple, and that we can code very fast. Like we did the simplest approach possible, because everybody must use it. So go find your home and click. And that's all, and you get your one kilometer radius, and the kids will be able to travel inside the circle, so very simple to use. We coded that in two hours, so that it could be deployed the same afternoon, the president announced the law. It's still live at this onekilometer.geomatica.es, but I don't know, maybe if you want to calculate one kilometer for some reason, you can use it, but it's not used anymore, and we hope we won't use it anymore for lockdowns. Okay, we wanted to be easy to use, beautiful, deployed very fast. We end the tool that everybody, everyone needed in the right time. So as a technology, we use Mapbox GL as a JavaScript library and this is one line, and one line of turf to make the magic, so just a circle of one kilometer, that's all. An important thing, we use Mapbox base maps, because they had a free tire of 50,000 map loads, so this would have to be largely enough for what we expected. And there's the GitHub repository down with a mid license, if you're interested. Okay, let's start with the spreading. We finish the application, we deploy it in GitHub pages, we make one tweet, we don't have, we have I think a thousand followers, so not that much. And we put a dozen WhatsApp messages to friends. We hope that our friends would put this, our link into the WhatsApp parents groups from schools, you know, and then it would be possible that they would be retweeted. So we went to bed, it's eight o'clock at night, and we went to bed, and in the morning at 10 a.m. we had 10,000 visitors. So from 10 messages to 10,000 visitors. We were happy, but a bit shocked. We went to analytics to see the sources, and it's what we thought, but much faster. I mean, you can see 80% is direct, so from WhatsApp, it clearly went viral on WhatsApp. These stats are not the stats of the first night, these are the stats of the whole two weekends that it was, the law was enforced, but at that moment it was like 95% WhatsApp, so it was almost everything WhatsApp and some social media. So parents sending and we're sending the link. So we were very happy. But three hours later, we have 20,000 visitors per hour. So the famous exponential growth, keep calm. It was funny because often newspapers then were trying to explain exponential growth to citizens, if you remember, stay home because if you spread the virus to 10 people, blah, blah, blah, we went viral in the pandemic. So okay, so what to do, what to do, back to problems. We're running out of base maps. You remember we have 50,000, we're almost done, we need something to do. And we run out of the free time, so let's pay, pay Mapbox. We took $400, we thought, okay, it's also some publicity for GeoMatica, so we can spend $400. They immediately disappeared like flushed in the toilet and we were running out of cash completely. It was insane, we couldn't do that. So keep calm and think of alternatives. Do it yourself, base maps. We don't have time. We don't have time. Put some ads to pay Mapbox. Well, the idea was a non-profit application, so not possible as well. Another alternative, Mapbox posted a few days before that they were supporting COVID-related applications. So we decided to email Eric Gunderson, the CEO of Mapbox, for a Mapbox unlimited account. But of course, when it's noon in Spain, it's 5 a.m. in America, so Eric Gunderson is sleeping. And we got thousands and thousands of simultaneous requests. We need to do something. Keep calm. What can we do? What can we do? Finally, we got the solution. The open source community pointed out to the right direction. A free and unlimited dial service from the Catalan Geologic Institute. So thank you to the Institute Cartographic, to RAF, to Jane Kietz, and all the awesome Spanish FOSS4G community. They helped us a lot. And okay, it was on. So we could relax. Well, relax a little bit because the media were calling. We were on almost all Spanish media at some point. Some 10% of the traffic came from referrals, as we've seen before, the news links. And well, and some of the media were very nice. They put our name like in big letters. Some of them were not so nice. We'll see that later on. But suddenly we were in trouble again. The traffic continued to grow. It continued and continued to grow. We had four million visitors the first weekend. So the servers were burning. I mean, it was growing and growing and growing. So we decided that we must cache them. Only solution. We cache the cartographic tiles with Amazon Cloudfront, which is very, very scalable and affordable. That's what we needed also. So that we were able to resist all the traffic and make the servers relax. And it worked. It worked very well. Here you can see the bytes transferred. I mean, it's every hour, it's like 100, more than 150 gigabytes, which is maybe usually the monthly maximum of a normal hosting, maybe. So it worked well. It worked well. And two days later, Mapbox agreed on a super free account. So finally we decided to put Mapbox. So thank you also to Mapbox. And it worked. It worked well. But we hit some hard limits also on Mapbox servers. So too many concurrent geocodings, even for Mapbox, they also had to work and change some limits, some parameters for these massive concurrent users. We had eight million users in two weekends. You can see the first weekend and then the second weekend even more. Okay, that's it. The adventure is over. Some final considerations, some anecdotes, maybe. I will start complaining a little bit. For example, La Sexta, which is one of the biggest TVs in Spain, they put an iFrame in their web page and they encrusted our application. I don't know. Maybe it's legal. I don't know. But I didn't like that. Or once, one time, a girl contacted us. I have a blog called Pientelo Actuo, which is, I think, therefore, I act. I would be very happy if I could put your application in my web and my blog. And we said, of course, you can. And then they showed this in El Armiguero, which is the main late show in Spain, but presented with a sponsor, like Yoigo sponsors this section. So we didn't sponsorize our app, not to make profit. We didn't get any money, but El Armiguero got sponsored by these presentations. I don't know. Maybe it's legal as well, but I don't know. I found it ugly. Okay. Complaints from people. We got hundreds of tweets and mails that we put an answer almost. And like always, it's mainly complaints. A lot of people concerned for the privacy. I mean, if it's a free application, they thought if it's free, they are using our data for whatever reasons. And so we received a lot of mails complaining of and asking for privacy policy, privacy settings, blah, blah, blah. And other funny people were the ones who instead of clicking, went to find our mail and emailed us asking, sending their street and their number, like I live in the street this and with the number that, and please calculate my kilometer. Okay. Compliments. Compliments to end the talk. There were many, many compliments posted in virtual Spanish media, press, TV, in social media, many public organizations from the smallest local police, for instance, or to virtually all political parties also, like from left to right. Even some famous people like posted about us like Alejandro Shant. Sorry, I don't have the image, but believe me. And also some controversial people also posted about us like the president of Venezuela, Nicolás Maduro. And why would he do that? It's because they used it in Venezuela. The one kilometer became popular in Spain, but it was a world map, so it could be used anywhere. And when Venezuela made an identical law one week later, one kilometer, they thought they could use our app as the official way to calculate the kilometer. So they promoted us in Venezuela. And it was a complete surprise. And let's finish. If we have time, I think we have, it's very short video. With probably the most awkward moment of all, when the vice president of Venezuela makes a tutorial on how to use our app on prime time on TV. Okay, enough. I know it's very weird to finish like that, but I feel like after 15 years of politicians ignoring amazing GIS applications we've done, it's a fair compensation that the vice president makes a presentation of our simplest web map ever and on prime time on TV. So as a conclusion, also I would say for the whole experience, I would say that we should try to make useful things and not only complex things. So thank you. Yeah, thank you very much, Martín. That was a very nice presentation. Thank you. Yeah, as you were mentioning, we don't have questions for the audience, so I can maybe digress a little bit until they come. It's funny that, yeah, the simplest tool can be the most useful. And that's a very, it's a recurring lesson that we learn that we try to build very complex user interfaces and then nobody uses them because they are not for the usual people. But yeah, probably you didn't know what you were doing when you were creating a tool that does these very deep zoom levels because that's the hardest thing to serve as probably the people from Mathalium in the room can also at best. Also maybe you can't disallow next time iframes or at least from very specific referrals. Maybe you can redirect them to some landing page or something like that. That's something that they do, media do this all the time because they are experts in serving large scale but then they are doing this kind of, I understand that this was probably because I looked down, everyone was busy, everyone was super stressed and they did just what they so fit. We didn't have time to make these things Jorge, we were just like… No, I'm talking about those guys, not you. Creating the iframe instead of maybe calling you and giving you some money to maintain the site instead of killing you with requests. Oh no, nobody offers money. Okay, I don't know if there are no more questions. Thank you very much Martí and Oscar and the rest of the Geomatical people. I think with this we can close this session. Thank you everyone who attended and enjoy the rest of the conference and see you around. Bye bye.
