 This is Sebastian talking, and we have Alex and Yelena Schimler as well. So first of all, a slight disclaimer. It will not be super technical today. We'll just give an overview of the last 10 years in OpenStreetMap, have brought in what's been happening, and first of all, we'd like to ask the room who a few knows or knew OpenStreetMap before the talk. Ah, that's almost everyone, I would say, about 95 percent. Who's using it consciously or subconsciously? Okay, I would have expected this was three quarters or something you didn't show up. Yes, that's the key. Maybe I'm not using it. Okay, many use it without knowing it, because our data is in many applications, apps or whatever, and it's not that prominent. There are some services that are quite well known, but for which you would not know that OpenStreetMap is the data behind it. Who of you has contributed? Okay, that's about a third or a half maybe. So that gives me some rough information about you, and now let's give an overview about OpenStreetMap. The name OpenStreetMap is actually wrong. Actually everything is wrong. Open is correct, but it's not a street map. It contains buildings, forests, everything really. Anything that somehow exists in reality over a certain extended amount of time, more than a few weeks, perhaps Christmas markets are not really the thing for us, but anything you can see, and there are no relevance criteria. Anything basically that is geographically present, it gets in there and everything is kind of noticeable. We haven't really explained why it's not a map either. Why is it not a map? Well actually it's a geodatabase. A map is a thing that you can look at, and that's it. You can see where you can drive or something, but in OpenStreetMap that's the raw geodata. Exactly, and such geodata is useful in many ways, much more than a pixel-based image can be used for. It's not fantastic because it's open or free, but because it's much better for developers. If it would not be free, developers could not do anything with it. That's true, but many people demand complicated license agreements before you work with the system, and for us you just accept the ODBL license, which we do not want to talk about. No license debates. We know that many people go to your OpenStreetMap.org and look at the map and think, what's going on here? What's this all about? We know the page isn't that bombastic. It's more directed at the map community, but we have great third-party developers who use our database and do fantastic things with it, and that is much better than you could do in a democratic community process. Some just make applications on their own, and these could be companies that can monetize this as well. Fantastic things are created this way, and that's because we have a whole lot of data by now. 130 million buildings, 60 million kilometers of streets and parks, and more than 7,000 dispenses for dog feces, plastic bags. And that's not a very German phenomenon either. Most of these have been mapped in Germany, but in Argentina I've seen pictures of those as well, and they are in the street map. And that's what happens when the detail at some point is so great that nothing else can be mapped. That's when you start mapping these things or cigarette machines. These are six digits. These are six digits. A huge topic for us is the currentness of our data. You don't see that in all our applications, but for us in the database, this is one of the most important or the highest priority. Our data maps reality as it is now and not a number of years ago. A commercial data provider, a map provider will be driving along a street network and will not notice if something changes. These people will be going there once a year, and they realize, okay, now they realize something has changed, but with an open street map we have a community, and everyone goes out there and looks over now and then decides, okay, something's changed. I'm going to enter this. There was a path in my area that they redid, and I was waiting until finally they would remove the barriers. And I came home and suddenly I was like, oh, the barriers have gone. I went home, wanted to map it, and someone had been quicker than me and had probably climbed the barriers. And I was talking to someone and then later, and who told me, yes, I had been waiting for that change as well. So this is how data acquisition works. And what we often hear is there's open data everywhere. This is great that open data exists, and in the geographical field there is a lot. It could be more, but there are a few. There is from one federal, German state to another, for example. So people say, why don't you just get an import and put it all in, and our answer then is no. If we would import data in this way, things would happen like in the U.S., you see streets of motorway crossings that look like this complete chaos, this is a state that we do not want. And importing existing data gives us four issues. Official data is not perfect. Sometimes it looks like the picture that we've just seen. These are American data, the tiger database, that's the public domain database, the American official geographic register, and these are under a few license. A number of years ago we said, let's import them. Someone said that, some community said that in the U.S. and someone decided to do that, and since then we are fighting, we are struggling with this because the problem is, well, the quality. Every database has problems. Every database has errors. We don't want to say this way that our map has no errors. Of course not true, but we do not want the errors of these other databases in our own data. Because the thing is, if we have our errors, we can correct those, and that's very important for us. And when we import this, also the problem, we may have all kinds of building outlines, let's import all those, but there are existing buildings already or streets that are somewhat moved, and we then don't know which of these data is actually more recent. This property is on the building that if the other copy does not have, so it doesn't lead anywhere. We have this data three times, and it's all wrong in some way. So if we have empty cities somewhere, very rare thing these days, we could import into that, maybe, but then that leads us to the next issue and that is editing those data because that means there is no map there. And if no one is there to put those data in, then no one feels responsible, and if someone climbs the barrier to register a path and the path disappears and it all is changed, then the original map will feel a responsibility and think, I also wanted to enter this in the first place, I should correct this. If we take data from open data, this data is just put into our database once and then never touched again. And last but not least, license. It shouldn't be self-explanatory, but what's important is if we import data that comes from open data sources under some license, whether that's compatible or not, if we want to change licenses, we may have to throw this all away and maybe all of the things that have been there before that we removed for the import, so it's difficult. So that's why we have classic mapping on the ground. We just get out with a device or with paper and try in our surroundings where we have to be to find objects and figures. You just start, the way we start is we have the GPS, we can create tracks and we can then paint or draw roads over those tracks. The problem was that one then was different accuracy and some devices a few years ago were not that good because of the distorted signals that we had, that problem has gone. But if there's a cloud over us or we are in a difficult situation with buildings then we have distortions in the GPS data, enough distortions I would say. Earlier we had the big problem of the threshold. No one had a GPS device. The threshold to start working was high and there were devices like Garmis that was a big vendor. People that had that had a good device and all the others were just excluded because they would have had to buy expensive hardware but these days all smartphones have GPS. But exact registering is still very time consuming because we all keep increasing the amount of accuracy. We see we want house numbers. We want all paths, dog feces, plastic bag dispenses. We have other methods though, newer methods. We have photo-based mapping and then we have what we call direct mapping. Shouldn't we have checked whether that's a protected term? Well, photo-based mapping that's simply as we get out with your phone GPS you take a photo and you see okay that's where I took that photo, that's where this mailbox is and these are the opening times of this shop and may know which side of the road it is as well and you can then enter all that at home even if the camera does not have GPS and I know the area I can just photograph that square and then remember where it is and enter all the details later. So part of the photo mapping are satellite images as well being a satellite image is something that we can use for updating roads. That's fairly accurate. It's a good start. We can use that. And a relatively young project that is close to OSM is map-pulinary. It's crowdsourced street view. We can use these images for mapping which is also interesting because the perspectives from the streets is what we then get and we can count stories in houses or vending machines and our own photos I've just said and you have to talk about direct mapping. Direct mapping. The procedure used to be we would go out of the GPS device, went home, connect the GPS device to a computer or load it up and the problem then was while we were on the street we didn't get any work done, finalized. We would just register the data and the actual entering at home would take about as much time as it would have taken me outside. You want to be walking outside and have a Sunday walk somewhere and not take another three hours to get all the data in because people just don't have that amount of time, don't want to invest the time. I'm in a cafe and I take my smart phone and wait for someone and at that time I could type in opening hours and accessibility data and it would be nice if I would not have to do with that data later. You were talking about accessibility. There's a wheel map which is connected to the OpenStreetMap database and micro editor that you have in your hand and you can immediately upload something to OpenStreetMap. You don't have to edit it for hours on end. It is there immediately. We predict that in the future special interest editors will increase. Some things are difficult to register. For example, we have public transport connections, lines, not the times but where the lines are and that is quite difficult and quite cumbersome. They say hardly anyone does it. It does exist in great cities, in larger cities but in villages even if someone is there during the mapping we will not want to register all those lines so it will be great if we have special editors for that that would make this easier so that's where we are moving hopefully although some apps are also dying out and we'll see how we may be able to continue this. If you have native if you do native more of that please talk to us. We have huge numbers of projects for that. A big area is for a few years is armchair mapping since the aerial photography for example being in Yahoo et cetera in Mapbox since then we are able to do it from home and basically copy every photography and you don't have to go out and I can just map areas where I never go or where I only go in 10 years and I'm happy about having a map for them for example the most famous example is the hot project in open stream if there is anywhere catastrophe or crisis Ebola tsunami any kind of crisis really and open streamers ask for help and these people organize themselves using this hot project using using the areas of the areas that need to be mapped and taking air photography and mapping those areas and these are donated by someone and for example we copy roads buildings and often these areas don't have any recent maps and even if I have a map from 10 years ago it might not be recent anymore and it's much better if it's from yesterday or the day before but even then it's better to have current air photography then I can get a real map and help the aid forces and there's also ways of taking the open street map offline if the area is no more net even that is somewhat controversial since some people criticize hot because this way it stops the local music growing and in reality often there's no one on the locally who can even do such a thing and for that reason we help them in this way but if an area hot is called for if that way already mappers have been active you should be a little bit careful but it's pretty impressive how quickly this go for example in the Philippines for example I made it in seconds and using by thousands of mappers creating maps in mere days alright so copying satellite images is somewhat problematic since you sit at home and you don't really know the area and there are some problems for example you can't really recognize everything from a satellite image with a bit of train you can see there's a building going do I draw the map directly through the trees or is there a stop there there's no connection and often there are mistakes made in this way so you have to be a bit careful and just check in person or what you already mentioned you don't really know the area so for example if you map in Africa I don't know is this a motorway or is it just a random road I don't know what we look what we always look like could be a dry bed of a river or could be just something completely different so you have to a little bit get used to the area and for example check how other people have mapped this area the problem is the age of the pictures often it doesn't say when this picture was taken and then someone someone on foot checks it and then checks the satellite image there's something new but it's not represented in this picture and then deletes it well obviously that's a mistake because you cannot blindly trust the satellite imaging well that's those are the most common problems with armchair mapping but it does really take us forward and it's very efficient and without ever photography you can't really map their buildings and for instance my neighbor will look a little bit funny at me suddenly sneak in and just sit there with my GPS and it's also incorrect since GPS has restrictions close to buildings and it just doesn't work alright for this reason community, community, community community, community the more the merrier alright I'm saying things I've never said before which I shouldn't be saying for us there's no review process there's no review process well there's sometimes this but sometimes discussions but they usually killed off right away everything just go in everything isn't private data so for example you shouldn't copy people's names sometimes people start to put in the names and the number plates associated with parking thoughts that was quickly deleted it looks like we do after all have relevant material so we don't have anything to do with that sometimes things like this happen so someone in Great Britain decided to draw something follically shaped we shouldn't delete that right away we already had a case somewhere sometimes someone had written something using their garden but the garden was actually drawn in that way so we could actually check that from the satellite picture and sometimes there isn't that much the barrier to entry is a bit too high the gap is a bit easier to just enter yourself as the chancellor but with open street maps it's a little bit harder and trolls just haven't quite reached us don't say it too loud currently most of the time if the data is broken it's usually done unintentionally since he's just starting to use the editon doesn't really know it so sometimes he makes a mistake and sometimes it gets automatically healed and sometimes they see buildings that are sort of square miles big but sometimes they message the user and say I'm sorry you made a mistake let's get together I'll show you how you can do this in principle our concept is he who does is in the right well things happen now I'm not sure it's both for the mapper it's both for the mappers and who just go across the city and check everything and if someone comes along oh you have just this should be an around corner instead such cases well they should go and correct it and instead of complaining with the software it's even more extreme you can do if you can also have a bit of power so if I have a software that shows lodgings and it shows if there's internet there and how much the hotel is and how much the internet is free or prices are sometimes a problem because it's hard to check and they also change quite quickly and some I remember Bakers was called one role 33 cent 6 year old information so if I build a software that shows lodgings and add additional information to these lodgings well there's a much more people that suddenly put the software in our work so basically I have influence if I have software that shows these things right we get criticism which is correct that says alright your page is stupid because XYZ is missing or this software is not very well designed or this very important feature is not there alright fine you're right but someone has to do it right our community you have to coordinate form groups in order to have communication so local groups is our motto and usually it's a geographic map of where people are and you can usually map people quite well that way and usually if I want to do an import I can have a chat with my local group and and check such matters that concern local areas and my local people and we can have meetups and it's really a lot of fun and you should check in your area if such meetups exist and it really helps newbies and you know check with us in Dresden some people show up who who don't come up on the open stream map but maybe they're writing a thesis or something related or want to look at the data and we're always happy to help and maybe once upon a time there was a meetup in your area just you know email them or create your own it's a lot of fun and you can have mapping parties where you just you know go together and just you know pick a district and you can just you know perhaps go a bit further than normally especially in local rural areas because rarely people get there and a lot of things are missing and you can really do a lot in a day in this way and you know as I said it's a lot of fun well important things well at least in the German community is the trifecta of blog weekly note and podcast sometimes other things come to mind we have mailing lists we have forums we have user blogs we have loads of things if you don't do it every day it's hard to spot so we have a weekly summary where some people collate the most important information and just sort of summarize in a single sense and I can just scan it and see what things actually matter to me and I can click those and I assure you every week important things happen and new things are being developed and being focused on certain things and it's just very interesting to sort of follow it week to week without it becoming boring there is a podcast in irregular intervals in varying formats and you could also follow that sometimes there's an interview with someone who's developed the software and they tell you everything about it about the software or about the development and you get some background information about how it works that's why it's so broken oh it's not broken there was a plan behind it otherwise the conferences there's a state of the map in various flavors international, European US there's a Baltic on the Baltic otherwise in Germany from FOSCUS there's a conference every year there's one dedicated OpenStreetMap track in this conference there's always talk about what they worked on last year or what they helped with and what they would like to criticize and everyone meets up and new projects are created there's also HAC weekends we forgot about those in this slide there's also an OpenStreetMap foundation and they just take care of the infrastructure and it's just a legal stuff so as a mapper you don't have to play too much focus and add use and just press but in principle you can see that the servers continue to run many people do a good job and in any case you don't notice them at all because they have to see the job they don't want to do it but just collecting the data but using it just to say oh wow a nice map with 1000 maps files we have a little demo now we have a short demo on our screen it's an OpenStreetMap this is very fast we heard that the rendering inside the browser takes longer than the actual computation as you can see it's already gone if you just add the data into navigation it takes longer now we have it takes a few seconds and here it goes it was a long navigation where you thought navigation was a hard for a long time but it's also fast you can also ask it takes a long time but now you see it can be done in a big way it's important when you're on the road and you take the wrong way then we have navigation for pedestrians for cyclists we have commode which is also for cycle and pass routes and very many different services so we have also mobile it was named scour now it's called scout one topic is a little bit dry because it's a topic full of misunderstanding that's what we have to say because I don't have to understand sometimes I click on the map but in the rain you just click on the map but sometimes you want to enter an address to get coordinates on your map and this is called geocoding I can say you can for example enter Berlin-Büchterstraße 11 or you may enter something like take me to the next restaurant or to the next ATM of some special bank applications of geocoding well you might think it's very easy we just put them into our database it's every two months or something like that everything is working fine and we have another 30 test cases and 29 might fail because geocoding is about understanding the culture of the country and the area because different countries have different styles of writing down the addresses maybe they don't have even street names in Japan for example you have credurants like squares with squares inside and so on and that's why it takes a form of geocoding instructions so geocoder for germany is because you have germination and you can just focus on it but when you try to do it internationally it's very difficult of course on street maps we don't have the addresses of every small village it's clear the problem is even bigger there are problems that you can't solve if you just type in Moscow well it seems easy big city in Moscow but maybe you mean the cafe called Moscow which is nearby or another small city which is also called Moscow and in another language it's called different so those problems you can't really solve them with an exact solution so they have the problem of finding and then the problem of ranking the results that you find often people point us to google and they say well they just solve it and we reply with oh it's not that easy maybe google is a bit ahead of us there was a sweat on a board and someone told me well on google I can just enter Mona Lisa and as a result I will get the Louvre that's perfect and it's just easy I don't have to know that Mona Lisa is in the Louvre and well then I tried it and for me it didn't work I got an ice cream shop and a fitness studio and maybe then I tried Mona Lisa Paris and then I got as a result a shop which was permanently closed so we just tried it with open street map and we just entered Mona Lisa and what did I get the exact location of the Mona Lisa painting inside the Louvre building so of course it's just one example which worked out very well but well if it hadn't worked out we'd have chosen another example of course in the software so to dive in a little bit into the software development the best thing that we ever created for open street map is the Overpass RP and some people say Overpass RP has completely changed the way we use open street map in the past it just had to download the whole planet file which wasn't that big in the past which was a whole dump and since we have the Overpass API you don't do it anymore Overpass is an API to perform complex queries on our data very easily so there's a query language and you can just combine any kind of detail you want QL and then we got Overpass Turbo which is just an add-on to the Overpass API so you don't have to make a query language encoded as HTTP request anymore so you have this wizard too so I'm just entering I need a postbox in Dresden and I press enter and I just get a map with all the postboxes highlighted but it takes the circle of Dresden just some query once directly on the outline of Dresden let's do it one more time again so this works for many different things you can combine administrative boundaries for example dog pieces back dispenders or search for stations nearby other stations so everyone is just searching what he needs for his special application and from this we have very much specialized maps for example a map for hostels and hotels and camping sites and this gets queried with the Overpass API and just shown on the map so this way you can create a new tool, a new website in half an hour or an hour one question that comes up frequently is well it's nice that you have this map there but somehow I want to display my own private data what I did with Google Maps when there was this overfledding in Germany so there was a map that was Google Maps to show where you can help, where help is needed and now you can do similar things with OpenStreetMap I had a map that was created for the football world championship and in our local newspapers there are long lists of addresses where I can go for public viewing but it's hard to find out what's nearby so with UMAP with this user defined maps I just entered those address lists into a map and it was easy to see what was nearby so I didn't go there anyway but UMAP is very interesting for data journalism so if you are a journalist yourself or you know some journalists then just point them to UMAP some of my best friends are journalists what you can do as well with OpenStreetMap is a special map you aren't bound to that special graphic display with a special projection an arctica if you look at an arctica on the default style of osm or google then an arctica is just a long stripe with the right projection this is how it would look where there are even streets and arctica and someone tried to delete them because they didn't believe there were streets but there are streets so on mobile devices vector maps have become rather standardized in the web that was a new development but sometimes you need maps for special interests for example cyclists they don't want to know where the highways are so I can instead map bicycle shops and refurbished work shops and you can do it very nicely in principle the design of graphic style is a process of filtering and deciding what to show you can't show everything in a map if you have a special symbol for divorce specialist or everything else and put everything in gets too crowded what you can do as well with OpenStreetVamp now is a 3D visualization so here's an overview of Dresden it doesn't look 100% complete but that's not what we aim for it's not about perfection because mainly we are a deal database and not a 3D model database to explain shortly how this is working those are not 3D models those are the outlines of buildings and we told we won't measure exact height but we will count the number of stories the building has and from that we can interpolate the height and we can define the kind of roof it has set a color and then you get this as a result so by now there are several render frameworks and software for it so there's another software that uses acceleration data from your mobile device like iPhone or Android and when you tilt your device then the 3D view is updated so you can have a look around the whole building so there are many web so you can also see the boats floating on the water one thing we don't do right now is collecting height data of the surface because we don't have the necessary devices for that and it's difficult and with barometric sensors you can't do that very good maybe you could somehow do it but you would need a new project for that because for now we don't really have anything if you see height data connected with open street map this is laser data connected not that well the resolution is not that great but it works for most purposes so let's look into the crystal ball 3D of course is the future that is going to be there's going to be more of that and what I would also predict it's not a huge prediction it has been brewing for a while and that's there were people that tried indoor mapping and there is a better tagging scheme for that now and this is developing Google has that now has had that for a while but it's difficult to register these things because you don't have GPS connection and you can't look into buildings from satellite maps either but I can imagine that we have devices in the next few years that could measure these things better could do better it would be interesting indoor navigation things like that and for those that have not contributed to open street map yet there's another request please just report errors we have a problem here because we have meanwhile we have the whole streets street networks don't change that much in a few places maybe buildings don't change that much but we have things like shops shops close once it's there and it's been entered and then it closes and a new one opens opening hours change you can't be there all the time you have been there on holiday so that's why we need many mappers that do a little that are registered and if it's just to report errors there's a facility for that on the website now you don't really need an account for that even it's practical if you do open one you can then ask questions if there are problems but there will be someone to work on these error reports and can correct the data and that makes us a bit richer and otherwise register sign up join us it's fun it's great and if you have interesting soft varieties come to us let's talk about it if you are an iOS developer or some other mobile platform come along we need you exactly we have at the CCH we have a booth stand we like to talk to you we are the broadcasting center we have huge banners so you'll be able to find us should we map the fact that we're there there is a map actually I'm I am and I'm Thomas and we do a podcast as well if you haven't had enough of us yet and we are looking forward to your questions now if you have questions please go to the microphones just go to the microphone please microphone 3 you just mentioned that there's is there a history in the open stream app was that loud enough the question was is there history data in open street map well yes and the option is there there is a project that's called an open history map I think because people were starting to enter Roman walls if this would be in the current map then you would stop seeing what you really want to see our data is not really prepared for time dependent data but another thing there is the version history of the actual database so you can see someone's deleted something opening hours have changed so you shouldn't that shouldn't let you believe that it's about the development of a town it's the development of the database signal angels have a question from the internet if in my area I saw that a lot of mapping has happened around me everything's been gathered already what are there still could there still be data that isn't missing that are useful but are often missing what is what we wish well I think there is quite some things that you could do house numbers, street numbers often are not there consistently points of interest I find very interesting very exciting how you can place restaurants banks and even in the large cities often our shopping centers for example do not have all the shops in our database so it's worth rechecking going through there once a year once every six months when you have time and look at those opening hours keep the map current and if everything is in there then we'll enter numbers of floors or stories or websites lighting rods whether the street is lit as a data for that too all right I have a question what about if there are shops entered do you know if the shops themselves proactively do something while it does have sort of advertising features yes there are cases but I think that the visibility of open street map itself is huge so many people will do that Google maps I know I have a few cases but with OSM I'm not so sure I know a few cases and of course it's not just in that map but a lot of software that's based on it so data that you see in Foursquare is actually from OSM so that's something that's worth something could you give me some examples just regular shops that enter themselves restaurants I've seen those and I don't know what else is there I'm not really actual hacker spaces yes hacker spaces are very popular they was entering themselves microphone 3 well there's light posts which you already mentioned there are already projects to do a blind navigation using this and using the position or the quantity of light posts using after for example say something like after the third light posts please wait there and there's the bus stop there there's also the marte card marte equals yes marte is a very popular hacker drink drink marte blind navigation there is a tag scheme for tactile elements so if you have the stick there was the idea if the raw data is there to then print those things in a 3D fashion and microphone 2 you previously mentioned you don't use official data well I thought that for few years ago there was a gift of official data and they were imported well it's not that we don't use that data but we are a bit careful with just importing it there is a semi-automatic process maybe where the data is being looked at but there are problems because some data is just not registrable so administrative boundaries you cannot go down out until the field you don't see those borders you can only get those from such databases so that's where we have to in a semi-automatic way import those and what's also interesting with official data is to compare if you certainly know how many house numbers there are in a place you can then compare and see where they are missing and then you have an evaluation of house numbers in no way have to go but the thing is still in Berlin house numbers have been imported speaking of Hexpaces for the last few years ago I tried to create a Hexpaces map using the Chaosverse assembly and I realized that if you try and print a one size map of Nordrhein-Western it's pretty much a struggle the data is far too detailed for example if you just want the rough edges of the forests and living areas but you just get massive PDFs oh that's not that much for example I went to two copy shops to two shops that were just not able to render it I tried two different ones but the problem is that the northwest Germany with the even just the contours of the forests are just polygons that are just ridiculously detailed including motorways that are mapped in both directions and if you try and map at that level what can I do there are options to evaluate the raw data printing actually is a difficult issue there is this function on OpenStreetMap.org it won't work for the whole federal state of Nordrhein-Westfalia but I know that there is a software called Maparrative can you print that? Well you can do things yourself there are people experimenting it is possible in any case but I don't think there is already software, finished software you have to Well I'm happy to tell you about my experience What can I do to contribute time? Report errors if you are anywhere and see that something is wrong simply just leave us a pointer and that will help us if you are out a lot just the GPS traces that you record or just take a few photos and automatically perhaps or just take time So one more question I belong to two thirds who have still haven't edited that's because since I've edited in Wikipedia and it just keeps getting deleted how do you handle relevance discussion reverberation was? Well relevance criteria we have hardly any of those there are these few conditions things that are there maybe not that and not these private things it's not about there is a path there and it's not official and just been trampled that's not the thing that we would say we would say that if it's there it can be registered and if it doesn't disturb anything we cannot change reality by not entering a path and if it's about editors or moderating there are some squalls sometimes because some mappers think that things should look this way and not another way and we then try to through different procedures we try to calm them a bit and if it's not possible at all then it uses sometimes they'll have to be given time to think they are blocked for a while no thing is that in most cases there are very few cases of the penis that we saw if that wasn't purpose this was a three week block actually it was it was just a warning and lock out if you leave your computer surely it wasn't you that ended this penis shape so you encourage people to talk amongst each other and if that wouldn't work there is the data working group or I don't know data working group does these things negotiate in the extreme case it's very rare so you don't have to worry I'm going to enter something and someone's then realizing this is the newbie we'll throw things away, no that's not how we work previously talked about aerial guidance which can make the map quite ugly making a map ugly isn't a thing ugly not everything that's entered has to be shown on a map but the question is the verifiability no aviation data there is an objection from the front I'm not so sure but it seems to be right that we have no aviation because they have no contact with the ground there is a separate project for that someone's saying typical OSM response but do you know the name perhaps what's important is that it is very valuable and boundaries of course do belong into the map we may not have post codes difficult to check there may be stones that we need to see thank you the internet has a feeble for example if I put in a house in Zirtor do I have to look for the properties of the house myself or do I get a suggestion number of stories or colors depends on the editor for example the web based editor which is the one in the new one in flash but the one in javascript if you go to open street map.org and click edits as soon as you have an account you have a relatively intuitive editor and if you then enter house then there are suggestions commercial house residential house and number of floors you can enter the address and so on it's quite cool if you can do things like McDonald's there and it would then suggest texts that have been used so you don't have to look for things like restaurants and stuff like that also if you have any further questions please join us at the assembly thank you Thomas thank you for listening this concludes the session open street map thank you very much
