 Let me tell you from about half an hour about a project that is linked to a project that has been discussed already many times today, OpenStreetMap. So OpenStreetMap is just as you'll see the follow-up of OpenStreetMap. So, do I jump on it? Not working? Okay, thank you. So I tried to do a content, but I'll skip it so you'll see. So, you all know the sea. The sea is roughly three-quarters of the Earth. And it's really important for sailors to know where to go. Most of you don't know probably that Christophe Colombe most probably had maps made by the Chinese, but did not talk about. Because in such a case, he would not have been the one discovering the US. But maps are extremely important for everyone going on sea as well as for people going on earth. Today, most maps are proprietary, both the sea actually also. Even though in the US it's not the case because most of them are public data so the maps are public too. But that's not what we know everyone else in the world. Most of the maps are outdated because the sea flow is changing all the time. The same as the coast. The coast is changing. Not a lot, but part of it is changing. And every change is a problem, especially where there are hurricanes and so on. Updating map is really expensive and time-consuming, especially with current process. And most of the time, updating charts, even if they are done, is not done by the sailor themselves because it's expensive. So most of the sailors, at least pleasure sailors, do sail with outdated maps. That is a problem. Because the rocks are there, but the sense that can be a problem is changing from place to place. So what are the challenges? The depths of the sea is known at many places, but not everywhere. As I said, most of the data can be very old, up to 200 years. They have been tracked and measured long times ago and people saw that the depths would not change, which is actually not the case. Because the collection of the data is really expensive, the data does not exist at many places. But people think that if they know the depths at some places, around these places the depths should not be too different, which is not always the case. As I said, it's important for all the sailors to know if their boat will go or not. If the process would change, then the maps and the collection of the data could be cheap and could be relatively easy as we see. So just a few words about OpenStreetMap. OpenStreetMap is a community database, so don't think of OpenStreetMap as a map, but mostly, as you've been told, as a database. Out of which some maps are done, many different maps, many different projections of the database are done. Some of them are maps. It's already quite an old structure. It has more than 10 years, more than 15 years, more than 1 million contributors. It started because of license restrictions, so the legal questions are essential around OpenStreetMap and all these maps' questions. The first license of OpenStreetMap was CC by SA, the same license as Wikipedia. But due to legal uncertainties, it has been changed to a new license, which is ODBL, since 2012. And if people tell you that they've got good ideas and that they want to make a new license to share data, try to convince them not to do and reuse that license. That license mainly is a copy-left license that engages and increases the change that the data would be reused, possibly also for commercial use. So I've just taken one example of a data close to the sea out of OpenStreetMap. That is the start of Neaport. So Neaport is here. There are two parts. One along the sea is Neaport Bat, and one deeper along the channel here, Neaport Stat, where there are most of the ships. So this is what you can get on OpenStreetMap. You see that OpenStreetMap already provides mostly what you need as a driver. So I would suggest that you stop using Google Maps and start using OpenStreetMap, through which you can use, through the easy application maps.me. I don't know if you've been told about that. Maps.me is a very simple application that runs on all these devices. It's offline, it downloads all the data from OpenStreetMap, and it provides very much information on top of that. So you've been told about the association, the Belzerne association, that today exists thanks to Ben and to the people, I was one of them, under the umbrella of Open Knowledge Foundation, which I want to thank today. So all of this has been told today by Ben, so I'm going to skip it. So what about OpenStreetMap? So as I just saw, OpenStreetMap is just the just. That's a short for about 20% of the job could be done on OpenStreetMap, because it's the ground, so we are left with about 80% of the globe. That will be done on OpenStreetMap. So we've already the blue, so now we need to have all other information. We've got the coast, we've got already most of the signs. So you will see that the signs are already, so all of these signs that you will see on an OpenStreetMap, you will already see on OpenStreetMap, but that's about all. You will see on that map, if I can do a live demo, I'll show you more later today, but I'll go on like that. So what is the Belgian coast? So the Belgian coast goes from here to here, so it's nearly a rectangle of, what have I said, 65 km on that direction on 35 km in the other direction. So it's quite a small piece of the sea, even though it's quite changing. Not many people see that, but it's quite changing. Who has ever been on the Belgian coast? On the sea on the Belgian coast. Who has seen that the floor is changing all the time? So if you try to sail to Dark Erk, let's go, let's try, you're leaving from Nipport, I've told you about Nipport, and you want to go to Dark Erk, easy, piece of cake, so it's really, so this is about 20 km, let's say 30 km, so easy, you do it in one, in half a day. But here there are a lot of banks, so a lot of sand, and with the, with the tide, so you can sometimes go, and sometimes you cannot. And you know all these sandbags are moving all the time, and they don't show you where they are. That would be too nice. Okay, so today, so this is how I made the measurements, so thanks to OpenSeaMap, it's really easy to plan your trip, just go to map.openseamap.org and go to tool-trip-planer, and you can plan your own trip, it's really easy, that easy, and I did two measurements, these to get the information that was on the previous track, and here is the only track of the steps, of the depths of the sea that you can find on the Belgian coast, only one. So let's say two, one, and a second one there. Only two tracks have been made recording the depths of the ships that have been sailing that zone. So there are works to be done. That's the idea of the trip. Those are the commercial days for commercial goals. Yes, yes, most of the time. So as I show you, it could be easy. So the idea is the following. We should record, in order to improve the depths of the maps, the maps of the depths, we should record at the same time, the depths, the position of the boat, the date and time, and the boat conditions. So that is, so you can record, but the presentation will be provided, and it's CC by SESO, everyone can reuse it. And the boat condition, acceleration and angles. So that is a bit tricky. So the challenge are, these are challenging because the boat should remain mainly vertical. Because if it's not vertical, then the depths you measure is not vertical, but you would have to do a lot of corrections. And if the sea is a bit rough, which happens from time to time, the boat is going like that. So it can be difficult. So the position of the sander should always be known quite precisely too. The open street map process is the following. The idea is that you've got a sander. So this is the apparatus that measures the depths. You've got the GPS that gives you the time and the position. And there is the Giro data that gives you the position and the orientation of the GPS. Then you go through a bus that connects to other apparatus, for example a computer, or a recorder, and that goes then to the laptop and can be recorded. All the metadata can be provided and all together, after processing, that goes to sander. This is the idea of open sea map depth measurement and you know what everything is working today. So the material, if you go to a shop, Uship or any other, you will find that many standard material ecosanders that are sold today allow you to record the depths. Some are quite good, but most of them are expensive. Not to say extremely expensive. This one is cheap, 30 euros. It's made by the people behind open street map. Because 30 euros, I hope I could sell you some, but I haven't got any today. And it records what? It records everything coming out of the ecosander itself. It has incorporated a six-axis Giro, it measures everything related to the rotation and the angles, a real-time clock, and everything is open, open hardware, open software, open firmware, and it does only cost 30 euros. If you want to make money, just do electronic material for ships, because most of the ships who want to have money do they for pleasure or commercially, they have got a lot of money. And today's electronic equipment is expensive, so it's possible to do it at least five times cheaper, I'm sure, but that will be for my next life. Okay, so as I said, the process is completely accessible and it's already working in open street map. It integrates well into open street map, and as I'll show you, it's possible to upload the data. We'll do some online activity if possible afterwards. So if you go to that page, you will see this information about acquisition, processing, and rendering of the information. And then you wonder, but that must already exist. And it does. It does, and that theme has existed for a long time. I've been busy working on that project for about six years, but not actively all the time. Teamsoft has been, it's a private project, publicly subsidized. So as I asked this morning, I don't understand why everything that is publicly subsidized is not free and open data, open source, and open everything. The teamsoft is financed by the European Commission and it's not publicly nor free. Okay, so if you register which I have done, I should be able to upload the data. So you see that these are the data done by the people active in the teamsoft project. So as it is not completely open nor completely free, it's not really complete either. The Belgium is here. You see that there are not many tracks. Every commercial chip is equipped with the equipment that could be part of the project. Most of them, as I said, would be interested in knowing more the depths. But we know that a lot of them are up here with the data they have already. So that is a project that exists, but if you want to get the data, you will see that today there are only small parts, small data, especially in France, for some parts on the French coast. So why have I decided to start again with this project that I told you I have been busy for more than six years because I decided this year to buy a boat. So today's boat, I've got a boat. So I decided to resume my project, but my boat is about that. So it's very nice. A little Archambaud surprise. It's a regatta boat. But you know what regatta boat is? So it's moving like that all the time. So it's a little tricky. Because as I said, the solder must be nearly vertical all the time. So either students of mine and myself will be clever. We will fix something at the rear of the boat that makes sure that the solder is always vertical, which is tricky. It's possible. There exists a lot of such instruments for people moving around with cameras. These devices that make sure that the equipment is always vertical. So this is one way of doing it. All the other thing is to put it behind that boat, in another boat, a smaller one, that is always vertical. That is the idea. So let's do the great boat, the large one that is about 7.5m, pull the small boat. This one has been made by the Swedes eight years ago. And it was used to map the flow of the lake in Sweden. So while not doing the same. And that was done using Arduino. So it's Arduino inside a GPS and batteries and so on. And a friend of mine, I was busy working with them, did similar boats in Brest to map the area close to Brest, which was interesting, because official maps are made also in Brest by Shaw, S-H-O-M. They are making the official maps and they were intrigued, integrated and interested in what would the non-professional do. They asked a lot of people first and did not believe that it would be possible to do something good, but then they had to change their mind. Even if you are not professional, but if you are a little conscious, we can do some good things. So with such a boat, what you can do, you can be systematic. You can, with a larger boat, you would go your way, but with such a boat, that is piloted by GSM, which has its own propeller and also battery, you can decide to move like that and do a systematic measurement of anything about lakes, rivers and so on, which could be interesting for other people too. We will discuss that too. So just to have some more time to go and do some things online. So if you want to do something, what could you do? So you could speak about the project, because mapping the sea could only be done if we crowd-sourced with enough people, otherwise it would be tough. But mapping the sea is not the only thing that could be important. Think. Today, Belgium has two important harvests. One is Antwerp and the other one is Zeebeke. Antwerp has a little problem. It's a very important commercial harbour, but in order to get to the open sea, you've got to go to and across the Netherlands. We pay every year more than 1 billion euro to go that. Nobody knows, because we've always done that. We've always paid, Belgium has always paid the Netherlands about 1 billion euro a year to go through the scale. And you know what? On top of that, every year we've got to dig the scale. People from the Netherlands don't care because they don't want to go with big ships through Antwerp. They go to Rotterdam and they don't need that. That's why we went Zeebrughe. Because in Zeebrughe, we can go anytime with larger ships. So it's a big problem. What if we knew, so we spent two times, one time to pay the Netherlands to go through the scale and the other time to dig the scale. So it's about 2 times 1 billion euro. We could do something else with that money. The same for the lakes and rivers in Belgium, especially Meuse, the scale and so on. If we knew the depths much better and we could all contribute, we could maybe spend the money differently. And there are many different, many other lakes and rivers where if we would work all together we could collect the data and that could be interesting for everyone willing to know the heights of the water which is, remember, 1953, the heights of the water was a trouble. That was the beginning of the Delta project in the Netherlands and there were 1,652 people died in February 1953, 26 in Belgium. Okay, so any help would be welcome with coding, material support, finding schools, teams or other fab labs that would like to build such do-it-yourself drones. When you're speaking about drones, most people speak about aerial drones, not a nautical drone. And you can take any of these drones and explore your own lake. So what about open CMAP today before going to the test? So I've just shown you that things are available. So this is part of the map which is a track about the depths so it exists and it's working. So it's also linked, the open CMAP I've not told you is linked to a very interesting wiki with every half of at least in Europe and from open CMAP you can also export the maps to use them on any device on the boats and there are some that especially accept these maps. So I just wanted to finish with a paper by Marcus that has been published in a known Gazette about open CMAP and I could not finish before telling you that very soon we will speak again about that project and anything about education and digital at the end of months of August where we'll train the teachers the directors and the decision makers who will first inform them about how to use confidently numerical and digital devices then on the 28th we will train them in these two schools we hope to do 80 trainings and there will be a scientific conference at the Royal Academy and it will be nearly free and everyone will get also electronic device so thank you very much help, please help make sure water depths are measured by crowdsourcing and I'm open to any questions before doing some if we've got time some interactive demo thank you very much thank you Nicolas, any questions? yes yes yes so the fact is I've tried to use this data but so far I don't remember why but I haven't been able to use these measurements yes I was not able I tried so it was Peter who told me about so I tried to download the data I don't remember for which reason I was not able to get the data there was again some strange legal reasons for which I could not get the data yes but yes but I but maybe I did a mistake but I did not so the idea was to reuse as many data as possible so first use the actual of the maps so we know that it's really tricky to use the maps that exist because both of them are copyrighted at least in our country stupid countries stupid laws yes about? what is that? why are we waiting for this? yes yes but I tried but I really I will try again no no it was not occasional format because that I would manage but the legal part is too difficult to manage oh it's really difficult it takes a lot of time so I just yeah thanks again so a mod that indeed is a provider of public and open data should be what I don't understand is that these maps are public data in the US they are not public data in our country so if you go to one of these public data maker which are still nearly paramilitary so they get most of the money through the military they tell you but we need to get money because we big maps that we sell and I said ok how much money do you get so what percentage of your complete budget oh less than 20% so get rid of the advertising budget and you will get the money back and provide the data for free and you're at the level but they've got to change their mind and that is too difficult at least the French are open yet so so this is what you get on OpenStreetMap or OpenSeaMap ok and you see here so you just go to OpenSeaMap or map.openseamap.org and here you see that first you can as OpenStreetMap edit the map yourself and add that is interesting the people behind OpenSeaMap have already added a lot of information so by default when you connect you see all these little dots here and these are the real time trips of the boats which are called marine traffic so these are a lot of data which I will very soon do so you see that there are a lot of boats so let's come back to a lot of boats a lot of boats so let's get rid of all these boats no more boats take some time to refresh I don't know so if you so you can get many different information which are so the Arbor for example you can click and let's go for what is interesting for us the depths you see it's difficult ah it takes ok in Germany there are some data no wonder why because Marcus is German and most of and the German community behind open script map is really active ok so most of the data concerned with the depths and the measurement of the depths are German so if we go to Belgium let's say see the Belgian coast or at any other place than the place around Germany you see that in the Zöydersee it's starting to be good there are recordings there are recordings I don't know why it does not come at that so you see that they are ok here we see the recordings not always all these little dots are the information about the Arbor there are quite a lot of information so it's and if we go to Belgium see what I've shown you that there is nearly nothing so that is Belgium so we've got a lot of work but thanks to the fact that OpenSeam at Belgium exists we could ask for money or Van Vlaanderen to help us yes so I talked already to Mr Van Vlaanderen to his Borgmeester and he told me oh yes that could be interesting so I told him that he could pay then he had to move so so if you want to know more about the other projects so this is the project so every link will be included this is the project that has been done 8 years ago so the idea is to have a logo that would measure the depths of the lake and this is the page where you can upload the data so as I wanted to show you everything is already in place so if you've got data you can upload them this is more information about the work of that little and this is about so the the proprietary so there it's possible to download some of the data but here you see that you've got French charts Lithuanian charts which is of little help for Belgium UK charts and US charts hopefully once it will be possible and one thing that people should know is that there is so OpenCPN.org OpenCPN is a software that runs on many different platforms on Arduino, on Windows Macintosh, Linux and on on telephones and tablets and that replaces all the proprietary software to sail with and it's really quite powerful, really powerful it allows today to read proprietary maps but it also allows to read these maps which I have not shown you it's possible to export the maps and one thing that is also interesting here if you want to go where is it? the Meteo weather if you are online which is not always possible when you are away on the sea otherwise it's a little costly it's possible to have quite a lot of information so if you are sailing close to the coast you get a network, a good network a ship network everywhere by G4 or Wi-Fi in the harbor and then you can get through OpenCPN map a lot of information about the weather so this is made for sailor by sailors thank you
