22 Sep '11

Bonjour à tous, Nous organisons avec /ch/open le premire campus Open Data en Suisse le 30 septembre et 1er octobre 2011 : http://makeOpenData.ch Je pense que ce sujet pourrait intéresser OSM. En effet, vous connaissez sûrement des sources d'informations ouvertes et libres proposées par les cantons ou la Confédération que vous souhaiteriez intégrer à OSM. C'est pour cette raisoin que je vous invite à venir présenter vos idées lors de cet évènement et peut-être trouver des dévelopeurs à même de vous aider pour les réaliser ! Meilleures salutations, François Bianco, pour le comité d'organisation -- Swiss Open Systems User Group http://ch-open.ch Swisslinux.org − Le carrefour GNU/Linux en Suisse − http://www.swisslinux.org

You might want to have another look at the details in the three pictures that I send yesterday. Which one comes closest to your ideal of a plan? And which one comes second? Before, you mentioned something about "compromis (ce que j'ai déjà fais avec de nombreux contributeurs)". I'm wondering what might have happend to their motivation and productivity. For three years, there has been a new and popular subway station in the center of Lausanne and none of the local mappers bothered to map its surroundings or cared about pedestrian routing. And there were not a lot of paths in the parc de l'Hermitage and the foret de Sauvabelin until I put them there. And in the Bois du Jorat there were plenty of duplicate and unconnected tracks and paths (Potlatch mapping?), with a lot of parts (still) missing. Those were the areas where I mapped and that I cared for. And those were the areas where I took the liberty to use highways as borders of area multipolygons. You on the other hand seem to take the liberty to tear up white space whereever it pleases you, because you feel that you are right. You create the white space for its own sake, because in the end you don't even bother to subsequently map the highways as areas. You don't need to lecture me that Riponne_3 is more "correct" than Riponne_2. You got it your way already. You need to find now some mappers on the ground who are willing to go beyond Riponne_1 in other places. Thorsten -- NEU: FreePhone - 0ct/min Handyspartarif mit Geld-zurück-Garantie!

Je sais que je joue un peut sur le mot mais ou final je ne voie pas comment on peut dire que dans le deux exemple que j'ai attaché on ne puisse dire qu'il contiennent autant d'information, car le ex1.osm contiens clairement plus d'informations. Since Stéphane brought up the Place de la Riponne earlier, why don't we stay with this example? That would probably be the most appropriate way to discuss what kind of information is important to Stéphane and what kind of information is important to me. Riponne_1_ orig.jpg shows the Place de la Riponne as it was before I touched it and with which Stéphane seemed to be perfectly happy. Riponne_2_shernott.jpg shows the Place de la Riponne after I had a first go at it and added the corridors and stairways inside the subway station and some pedestrian ways on the place. Those of you who know the place will realize that the subway station is greatly simplified and stylized. If you have a look at the entrances to the east, you will see that I changed them from a more exact to a more useful way (with regard to routing for pedestrians and wheelchairs). And you can see the shifted borders of the place multipolygon, with the old borders in pink, which I had left around in anticipation of Stéphane's reaction. From my point of view, I added quite a bit of useful information (and also exactitude) to the place and took away some information and exactitude that would be expected in a zone plan, but not have an purpose on a map. So this is a practical example for what I meant when I was talking yesterday about maps and plans. Riponne_3_stéphane.jpg shows the Place de la Riponne 2 days later, after Stéphane had his way again. And now that I have confessed my sins of simplification and stylization, we'll probably soon be able to witness some more activity around the subway station. ;-) So when Stefan Keller proposed to get some wider spectrum of opinions, I think the question that needs to be answered (for every area and for every community individually) is whether we want to create a plan or a map. We can't have both. At least not in the same area. We might be able to toggle and prioritize the rendering of certain tags according to map type and zoom level. But to my knowledge there are no algorithms with the ability to produce the kind of simplifications and stylisations that you make on a map, because that implies decisions about moving, combining and deleting ways and nodes.

Bicycle parkings in Lausanne, Prilly and Epalinges

I recently participated in a surveillance of publicly accessible bicycle parkings in Lausanne, Prilly and Epalinges, so I do have data (I just made sure that I own it) in the form of geotagged photos describing their nature and the number of places. Where the individual places are packed to densely to be useful or where the supports are broken, only a part of them is counted. (There are some official guide lines on how to count bicycle parking places...) General two-wheel parking spots without bike supports were not counted in this surveillance.

If you wish, I could put the issue on the "agenda" the and get some general/spectrum of opinion? Thank you for your offer, Stefan. I appreciate your experience and opinion, but I'm not sure if a general spectrum of opinions will be of much help in this specific case. Apart from the fact that I don't particularly enjoy the feeling of my mapping around Lausanne being surveilled and micromanaged by Stéphane, it seems to me that Stéphane and I are motivated by fundamentally different visions. Stéphane seems to want to create a plan, I would like to create a map. Now I couldn't say of either one if it was "right" or "wrong", but while I would like to participate in the creation of a map, I don't care to participate in the creation of a plan. For those of you who wonder about the difference between plan and map, the definition in the (German) Wikipedia (http://de.wikipedia.org/wiki/Karte_%28Kartografie%29) is as follows: "Von Karten spricht man immer dann, wenn ihr Maßstab zu einer Generalisierung zwingt. Lassen sich Phänomene der realen Welt nahezu ungeneralisiert und dann meist großmaßstäbig darstellen, so spricht man von Plänen (Lageplan, Bebauungsplan)." Or in my own words and in English: On a map you are working with a lower scale, so you have to generalize and stylize certain phenomena of the real world. On a plan you work with a higher scale and reproduce every little detail of an environment, very much like on a technical drawing. I have heard that the principle of OSM was "map everything". But I believe that there needs to be more than just this one principle to ensure a healthy balance. I am motivated as much by the idea of completeness of the data as by the goal of simplicity, elegance and usability. For me, to find a building on a street or the entrance to a subway station on a place is good enough. I don't care to know about the exact location of every curbstone on the street. In fact, I don't want to know about it, because it distracts me and demands way to much attention to process all the unnecessary information. So when I am mapping, I am striving to find a balance between exactitude and stylisation. And while I am not mapping for a specific rendering style, my aim is to allow at least theoretically a simple and clean rendering of the data (and routing of course). As I have already said, to my knowledge Stéphane has done extensive tracing of aerial images in the area around Lausanne, quite detailed inside the city, and more roughly (and certainly not up to the standard he tries to enforce upon my edits) in the area around. So if he wants to impose "his way" of mapping onto the whole area, as he has de facto done to this date, that's fine with me too. But then he'd better motivate some other mappers on the ground who are willing to follow his vision of creating a plan (in forests, parks and farmland) and provide all the paths and other details in and outside of Lausanne that he has missed so far.

Ask for mediation

Hello every body, English bellow. ==== Je suis désolé de cous importuner avec ça mais j'ai un problème avec le contributeur Shernott (http://www.openstreetmap.org/user/Shernott) ou je n'arrive pas du tout avoir une discutions constructive. Ce que je retiens de la discussion c'est qu'il méprise les contributions des autres et que les sienne par contre sont irréprochable. Bien sur j'espère me tromper sur l'image que j'ai de lui et j'ai aussi mon lot d'erreur mais actuellement je suis dans une impasse). Le point central de divergence c'est qu'il veut absolument que toutes les zones aillent jusqu'au centre des routes ce qui va a l’encontre d'un véritable plan de zone de bonne qualité comme [1]. Et il est vrai que je ne veut pas un OSM au rabais. Pour être claire j'ai joint les messages échangé. Actuellement je n'ai pas répondu aux 2 derniers messages. Merci d'avance. ==== I'm sorry to bother you with that but I have a problem with the contributor Shernott (http://www.openstreetmap.org/user/Shernott) with one I can't have a constructive discussion. What I retain of the discussion is that he despises the contributions of others and hos one are irreproachable. Of course I hope I am wrong on the image I have of him and I also have my share of errors but actually I am at a dead end). The point of divergence is that it insists that all areas go to the center of roads which doesn't go to the direction of having good accurate zone plan like [1]. It is true that I do not want an OSM at a discount. To be clear I join all the exchanged messages. Acctually I havn't responded to the two last message.

In OSM a road is usually represented as a line, and if there is a forest on one side of the road and a meadow on the other, why not having the road as the border between two areas?

This is true of course. And it is also true that there are plenty of forests, fields and residential areas that go ACROSS roads and tracks. Many of them were traced by yourself, which is by the way a work of yours that I do highly appreciate! > I'm sorry but your cleanup don't represent the real and what you named the mess is the real. And OSM should represent the real If you have such a strong urge to "represent the real", why don't you start with all the areas that go ACROSS roads? You yourself have painted plenty of areas ACROSS roads. That doesn't "represent the real" either. So why don't you start there? Why do you have to "correct" and meddle with my work? In my eyes the fields, grass, meadows or forests underneath a way represent reality much better than the white space that you create. And let me tell you what you did: * You removed forests, just because you couldn't see the trees on the Bing map. Hint: the Bing photo was taken in winter or early spring, that means the deciduous trees don't have leafs, which makes them hard to see. This is why they can compare photos of summer and winter to officially distinguish deciduous from coniferous forests. * The space you added to roads, tracks and paths was much to wide. There are paths so narrow that you can barely set on foot in front of the other. What you mistook for paths, are fences along both sides the path, but the paths and tracks themselves are very narrow (and themselves in a kind of meadow between the fences) * You traced highways from the Bing map without taking care of its offset, so your roads were off a couple of meters. How is that about "reality"? So I suggest, if you want to make things "more real", then don't do so based on what you think you see on a four year old satellite photo. Go out, and look at how things look and feel in reality. I DO NOT appreciate at all having you behind my back, correcting every step I make, which you also did for some edits inside Lausanne. If you prefer to have the Riponne look "your way" but based on old photos that have nothing to do with today's reality, just say so. I'm so sorry to tell you this, but what you are doing here looks and feels to me like tight-ass nitpicking. > From say before I revert changset 9162875... If you insist in messing with my work, feel free to do so. In that case I will simply stop contributing in the Lausanne area and you can keep having fun with your satellite photos, which is something that you are very good at.

You have an interesting definition of "collaboration". If your principle of "space for roads" is so important to you, there would be plenty of places, where you could apply it first. If you insist in having things the way you want them in an area, whose landcover, tracks, roads and paths are currently traced and mapped by another mapper, I don't call this "collaboration", I call it "dictatorship", or "being a dick". BTW: You fucked up some of my edits that I traced last year and you didn't even notice, because all you can see are your outdated aerial pictures.

If you are on the ground and MAPPING in an area, then you should MAP there any way it suits you. But if you feel the urge to "CORRECT" and "IMPROVE" what other people are MAPPING while they are still active on the ground in that area, that's an entirely different story. And on top of that, if you fail to notice that there were GPX traces around the lakes I mapped in a quarry and you replace them with some other lakes that only exit on old satellite pictures, then I call that "fucking things up", even if you spent a considerable effort to follow contours of lakes that don't exist anymore in that form. I am fed up with your idea of "collaboration" and I suggest that you send somebody else with a GPS and a mountainbike up into the Bois de Jorat, since I won't touch it anymore.

Re: [talk-ch] Ask for mediation - Shernott talking about changes in Lausanne
by tnk＠gmx.net 06 Sep '11

06 Sep '11

Hello again! > Pour un exemple plus simple qu'est la place de la Ripone > (http://www.openstreetmap.org/browse/relation/391928/history): > Mon changeset initial http://www.openstreetmap.org/browse/changeset/4936589 > Modification de Shernott http://www.openstreetmap.org/browse/changeset/9065948 Ok, it looks like we have to keep arguing, so let's shift the focus from the Bois du Jorat (which was my main concern) down to the city of Lausanne. After a quick glance on the change set proposed by Stéphane, I am not sure if it does tell the whole story. Since I don't like it when entire forests disappear for days, I tend to work with incremental change sets that leave the data intact and valid after each change. I was doing a bit more around the place de la Riponne than just changing the Riponne multipolygon, and I am not sure if it is all contained in this change set. The Place de la Riponne is a pedestrian multipolygon with pedestrian highways inside linking several points relevant for pedestrian routing. There is a new subway station with entrances from Place de la Riponne on the upper level and Place Arlaud (northeast of "Theatre Bulimie") on the lower level, so a couple of things have changed, which were not mapped yet. http://www.openstreetmap.org/?lat=46.523214&lon=6.632699&zoom=18&layers=M What I changed there: * Added an angle to the stairs from Riponne to Arlaud to represent their correct shape (they are actually old and well enough visible on the available aerial images) * Added stairs and pedestrian ways around the Place Arlaud to reflect the different levels there. * Added stairs, entrances and passages to and through the new subway station (in a simplified manner) * Removed stairs and pedestrian ways that don't exist anymore. * Updated the pedestrian highways linking the relevant points of the Riponne, so that they are useful for pedestrian routing again. * Aligned those pedestrian highways for more orderly rendering on Maps who show them instead of the pedestrian multipolygon or who show both. (Those pedestrian highways are arbitrary anyway, it's a place after all.) * And yes, I am guilty of extending the shape of the Place de la Riponne multipolygon to some highways that are its physical boundaries while leaving the way with the nodes of the old boundary around, just in case somebody should wish to change it back - which Stéphane promptly did. While we are at it, I could mention that I added a little meadow and forest between Av. de Riant-Mont and Rue du Tunnel, whose absence on the map didn't seem to bother Stéphane despite its visibility on aerial imagery. But as soon as it was there, he had to correct its boundaries (I used Av de Riant-Mont to separate the meadow from the residential area, which didn't suit Stéphane): http://www.openstreetmap.org/?lat=46.525628&lon=6.632919&zoom=18&layers=M And I could mention that I added a little park with playground, parking space and ball sport area between Rue du Nord and Rue César-Roux, whose absence on the map didn't seem to bother Stéphane either despite its visibility on aerial imagery. But again, as soon as it was there, he had to correct its shape and boundaries and to add an inexistent wall (which I removed subsequently): http://www.openstreetmap.org/?lat=46.525839&lon=6.636851&zoom=18&layers=M Do we really need to dig out all the change sets? Frankly, while I don't feel much motivation to map in Lausanne anymore, I feel even less motivation to dig up all the change sets and to argue about them. If my mapping in and around Lausanne sucks so badly that it needs constant surveillance and instant interventions and corrections, well, then I better put my time to a more worthwhile and productive use. Which is the conclusion to which I came already a week ago. Thorsten (Shernott) -- NEU: FreePhone - 0ct/min Handyspartarif mit Geld-zurück-Garantie!

Salut à tous, pour info, nous tentons de répertorier l'accessibilité des restaurants genevois en chaise roulante. Nous avons demandé au scouts de Genève de consacrer une journée à la mesure des restaurants (largeur porte d'entrée, hauteur sous table...) et le 7 octobre lors de fetons linux, nous insérerons ces données dans OSM. Pour ce faire, nous recherchons des gens qui veuillent bien nous aider dans cette tache. plus d'info sur le site: http://www.fetons-linux.ch/node/307 http://www.fetons-linux.ch/node/119 contact: Cedric BRINER 076 382 39 04 briner(a)infomaniak.ch Cdlt
