Subject Area
There has been no map for the forty-five bus lines in Metropolitan Managua, where around 1.5 million inhabitants are dependent on buses to commute to work or school. But engaged citizens used Free Technology and the power of collaboration to create the first complete public transportation map of a Central American capital, by using OpenStreetMap and through crowd-sourcing and also crowd-funding methods. We present the final products and talk about the publication of our outcomes as Open Data. We will also mention the local challenges and the nature of creating a map of informal transit information of a partially unregulated bus network It is a case study about Open Geo Software can empower people and enhance development, where information about transportation is lacking.

don't FIL yeah your presentation
please thanks so I'm very clear to be here things for for coming in joining into the talk and my name is Felix the Laplace um I'm a digital media consultant and
focused mainly on participatory technologies so I'm very interested in how general all people general people but also specialists can use technology to do something different or something new I've been involved in several free software movement scruple there now OpenStreetMap in Latin America and there might have been living in Nicaragua for over 10 years now but this talk is here really 2 % an initiative by the OpenStreetMap community from Nicaragua so In total over 200 persons were involved and I'm the only 1 who can be here that's probably because my roots German and they could combine the travel this state in my passports country and I hope all this is a good example of what can be done for open-source tools
and is also a big thank you to everybody was developing those tools because without it it it wouldn't be that easy so Nicaragua and I need a lot of people that don't know exactly necessarily where this so I just to make it clear Nicaragua is a small country in Central America and between Honduras and Costa Rica and it's a beautiful tropical country and the the 1 side the Caribbean Sea and the Pacific Ocean on the other side and it's called the country of lakes and volcanoes and know I personally can really say that that they're wonderful people living there and the sadly it's also 1 of the poorest countries or extradited say impoverished countries in an the American continent so when we
talk about transit maps actually and there are a lot of transit maps and we used to have transit maps all over the world and and the place there's actually a book that presents a lot of them but uh and when we look to Latin America Africa or Asia it's not necessarily true that there's a transit for every and transport stations system and I'm actually eager to say that probably half of the world has no mass and in parameters the same and some knowledge of the inca I was the 1st country in the whole Central America that has sentiment so the initial situation loss that the bus system actually has been crawling over time and not plants by growing so it just grew and grew and in this city Institute of transit regulation is a little bit behind reality and ends this all makes it pretty complicated to live and then I because you have a very limited mobility and access to Malaysia possibilities activities and um and chopped possibilities when you look at the sparse rather actually by the way of the letters you see on top and this is not the final destination it says God is great and this is the angel of love time Colombia Colombia's capital M may sent pretty well that is well developed city is not a place where everybody has a car where the access to public transportation is so attractive that everybody would use it and that's really what it's about it's about the democratic and democratizing mobility and making it possible for everybody to access all parts of the city so as a as a as a community we wanted to take a challenge and we also needed a Gold because if you want to force that could foster community you need of place where or an idea where you want to go and they wanted to have a state of the art transit maps for the city and may have to geospatial Revolution so there are a lot of tools there's a lot of documentation we could learn we can use them as so actually needed data and tools to create products to get the down and misunderstood together especially because the knowledge of the environment transportation system is actually in the head of the people it's not from so we wanted to engage people and so on have their local knowledge and because the maps of build for them we also wanted them to be part of it so to do crowdsourcing people and we wanted to have a diverse group of people I think it's very important because most of the maps have been made by mostly men mostly white men mostly with not necessarily the best intentions so when you open up the mapping to all kind of people it really changes what to map and how you map and what the and result so we actually ask everybody to help and we started building a community community of OpenStreetMap and to have a lot of people in the easiest citizens um students and um we started doing over
2 years a lot of map mapping parties over 200 person took the tools to get status so what order to consider using actually the whole OpenStreetMap environment has been very perfect for us and I think as far as I know we are probably the ones that there have been other initiatives that have been using Transportation Systems um by crowdsourcing approaches but we are the ones that we're using strictly OpenStreetMap tools and I really have to say it's easy and I would recommend everybody to do it if you want to do so we were using of course GPS devices they were good but they were not good enough at the end of it was just too complicated and using the DOS and tracker and further applications was really easy to get the data together and they're getting uploaded immediately to OpenStreetMap which made the workflow very nice but is not
just about using sensor technology and few papers this equates to will just print out maps and it doesn't take notes over it and if you have 2 different types of status sources it's actually more of a Bombay more reliable so we wrote the book bosses we took traces we ask bus drivers passengers or people waiting at the stops and the more people were involved a better be filed with the data the and then you have to imagine that that the that the system is not formalized so actually there are different ways of seeing how it works and if you ask 1 person you get 1 answer if you ask another person you get another answer so today we wanted to have as much as information we could have so we could to filter out what makes actually sense to get to a state which is more formal last the and this is really a challenge because mapping this it is
a little bit like mapping a mask because it's not very reliable the system it changes all the time it can changes because of traffic because of construction work but also because of weather conditions war because the busses were that on our be using it for other and for other purposes in this case for political reasons and another may be the biggest challenge for the best
because investors had no name before is you actually can see and this was the only date that we had before and you have actually the address of the of the best of modern name through defining names for Boston then there are
different types of past stared official ones which have usually assigned in a shelter but it doesn't it's not necessarily true if there is such a sign that it's really oficial bus or if there is no is not an official Boston we and then there are
a lot of popular bus stops popular bus of our common sense must stop so people chose to read and made it out that is good that the best of here so the bus stops there and we have of course to rural area connected so when you go to a rural area you actually have a different type of 1 how to procedure travel how to take these kind of model Texas or you can stop the bus whenever you want so all these challenges I very very make it makes a very complex and we had to do lookup we can fit this into this and the structure of a usually handle public transportation and putting it into OpenStreetMap most an interesting and process as well because the public transportation she's scheme is not too easy and not well accepted and so should be mapped that's as the official schema proposals and uh Mira collaborating with a tool called public transportation assistant which is a Google Summer of Code project of this year to be able to verify the now let's get to the products and we really wanted to get a product so it's not just about having the data in OpenStreetMap that's what we can do with it so the 1st thing created was a very simple web application that helped just to verify our own data but it was already a good start for people to use so for the 1st time people could actually look where the bus even though it's not too confortable um for detecting technical guys here we were practically using posteriors database converting the data through and possum into G adjacent and then displaying it demanded simple leaflet not so no magic here this 1 was more magic actually and I will take 1 out so we thought and it's really important to make a paper map out of it
it so we took the data and made a paper map that we could distributed people and of course this paper map was not is not just a simple paper map and what
you can use is also made in mind for people that are not used to read maps and to the local minima and particularities like um reference points and how people perceive the city was very interesting to them on the way to understand how people feel the city the city and how they move in the city and we then started a crowdfunding campaign to because he needed money to print those maps hence together if they monitoring OpenStreetMap team we were able to get enough money to get it to print them out for 2000 times and distributed to the people so that
people had a probably was not the 1st time in their life and on of course we invited press and everybody to the events because we still want people to be involved um and feedback is the most important part for us because it's really about crowdsourcing from the beginning and then you get to a point of crowdsourcing it is a non you'd better data how would you do that she needs more crowdsourcing because you need more information and he wanted to lower the barrier for contributions so it should be in our very simple upside he put a very simple that form that people can actually select the Roberts and
just make a click on and on and on and on envelope and sent this message and 100 steps so we could actually fix our data and still fixing it I think we never stop fixing OK
next step he wanted to do is routing and for routing we need something that very particular uh which is a sketch and there's no sketch the and so we could probably try to use them to think about how to extend the standard on use for informal friends and that this has been an ongoing discussion for years now the foundry outcomes and so we decided to to it simple and to try to make up a sketch so we know their frequencies we know their operation times so we survey it's this information and we have right now and we are transforming it into G fast which is the effect of a
standard form and transit data and once we have it there we can easily integrated into
the this nice open-source or everybody else can use do
hold background for us and them the and big importance and what we believe is Open Data so really really wants to be open and this doesn't mean that we use just open source tools and we give away the end product no we actually published the SPG of this paper maps with an open license you're going to publish everything raw data we are publishing everything so and the really want people to take the state had to build upon because we think that this is the way how development should work and we have already the 1st consumer of our data it's the m government youth organization that is using our data in their application although they're not doing the necessary attribution that's that's fine and it's interesting because when we talk about open open data we usually expect the governments to publish data and its citizens to consume it but now we have the citizens making the data and the government consuming so yes I'm OpenStreetMap is a great tool to build and it's a great tool to build a together which I think is a higher value than just putting on and then my company on doing that and so there are a lot of countries where this needs to be done right now so spread the world the worked into the world everybody can actually use those tools they're ready to use ready and do this and this is really just an example and we once again and thanks for developers to make that happen because without you guys it wouldn't be possible so thank you you you
thank you very much this is exciting
stuff from before we get into the discussion I just wanna let you know that a dummy arrived so we don't have a certain presentations of run off these questions comments questions about how to questions about the quality of their 1st of all how was how good or bad was the OpenStreetMap base map of the 2 started from and the 2nd was the view of bookmarked check to the the validity of the schedules with the people who are paid the bus drivers and when they and so the 1st question and the quality of data um it's as if it was a case Mr. had to draw some streets that were not in there but I think that's interesting on part about Open Data the more usage you give to the data the more you generally improving and so we actually improved a lot and then after the OpenStreetMap data in in and then I work on that and it's really grew by just using it but today that wasn't bad before readers so and it was just I think a natural man process on improving the data and and your 2nd question so which is an so about did this gets on the bus drivers and a few have faster a bus drivers all about the frequencies and this can and yes he did but I really have not received is that many support you have to understand that and in Nicaragua and has been quite big attention over do some capital sparsest before there has been a student process approaches for over 10 years and um so there's a lot of the year when you ask bus drivers about their regular info what they're doing when they're starting when they're ending so began some information out of it but he actually has to sit on the side of the road and to a list of howmany times the bus is coming down by every hour and from 6 in the morning to 9 at nite related to that and did you get any negative reactions because as far as I remember her my time because I was I'm not everybody is really interested in inference of parents you so word I you you you make quite visible what what was there and what's missing and me yes I think it's no we have we had no and no bad experience of getting out of this term but I do think that it's a process of opening up data and opening up minds that are full of furious so Emperor Kerala so thanks for doing this and this and that my question is if if you were to make this in another city or another country that what would you do differently than the way you went to and of course you get some experience some I think generally we did very well um I'll probably if I would repeated I would like to do it faster and if I do it fast I would probably invest less time in community fostering and more time into selecting people to do the work so I would probably concentrate now more on core group that we actually had at the end as well but um and a little bit less on on on on Monday part of workshops but I still think that both components are important so it's just more like a tendency on torture Tokelau croupier the identified so the presentation my question is kind related to what you just said you you mention the participatory approach and I really appreciate what is in your opinion that trigger the interest from the people who did things that most triggered their interests and my in my experience maps are just very visual and it's it's a great great way to to to get to people by the actual triggers make making something better for their personal local environment that's that's that's clearly the main motivation thank you president there our way of will and of what you've been doing guys have labeled and leave equation on trees an observation are you sure is going to be possible to go the tournaments in the conventional nominal of feature set to provide a gene that is trusted based on the observations you reason about days and we change mind most times t 2 Anthony said prominent and mind I I think once you have to product actually you convince people and especially when you're talking about bus drivers um 1 of the bus drivers that cuts the map was saying hey that that's so wonderful to have a man but he he'd had never saw actually than the way he was driving all the time and was telling me that when he started the 1st day he came to work they gave him the best but he didn't know where to go so here around the master and his passenger so
I I think in in the moment you actually have to product out and you have more positive feedback on people see why why why it's why it's actually um so we actually see why it's for them and make sense why it's good to have something like that so I do think that this change his mind any more questions or comments I have a question about the true willing how how did you get from the from the traces and everything to a nice solutions that road transit met as we do things always sold nearly done use some tools to make it easier is very good question and my only have a very set the answer to that and uh yes I wanted to do it automatically and forget it there is 1 master thesis actually discussing what mechanisms you could do to um may be generated in an intelligent way automatically um it's not implemented so I think there's who uh some of the plugin for big kid GIS um program that I don't want to name that now and which does a very bad job so it's really something that not solved all yes we were doing it manually tracing by hands that based on the day that we get out of street this is what you do you think this could be an approachable problem that could we'll to mobilize this Great Britain and other of engineers these and you know it just putting jeepers structures and burning busses and have some kind of a generated Geagea sorry was your question about generating the data decide in or DGT a fast both of OK and the above as possible I would say and mixture so how would you could you come people would it take to run in year engineers so I mean is that something that is in the domain of the feasible for I would clearly is a yes I mean if if if I look at the potential for all many cities still need such a such a map actually um and then it's it's nothing and I'm I'm few sure that a small group of people working with someone semantic can could easily create something which which would work well enough interest in French when the bank I'm running and into maybe just an addition and generating to give us out of the data that is already problem implemented so that's not really a problem the problem is how to get to the design because there it's just like coming from data to the design of a very complex question thanks for a great presentation and I just could yes expanded a bit more about how it once he had the data in OpenStreetMap you then got it how to do it is severely the apple or to do the tracing for the paper maps or do whatever it was just to just tells that more about that that process because the tools of that but it's of there a convoluted scheme in OpenStreetMap but you want very specific things out against and is interested about how that experience was viewed more heated OK and you can do quite a lot of interest using this simple Overpass API which from OpenStreetMap provides but it was not enough for for the special use cases we have so we're actually using and taking the data of OpenStreetMap putting into a posterior database and then um clearing at and processing at 50 1 1 the was I have 1 but gave some you seem to have done a great job was billing like a community for for actually getting the data and is that mostly the community that is doing data also development because you have some some development like you have you mentioned the apple and so on I want a bit about the sustainability on because I mean it's not a project is 1 initiative right so you have to take care of the software and that's usually more difficult part we need people that that have programming skills what was your ideas well you well the yes and a this I'm definitely we have more participation on the data side than on the on the programming side but we are will clearly based in the free software movement so we be most of the people especially the people and the call group um are very close to be programmers or are actually working on that most of the people were pretty young Sarah students of IT related certain courses think you all thank you very much Thank you write
