Subway stations in Seoul

Posted by thbz on 3 April 2015 in French (Français)

I have been working on the bus and subway routes in Seoul lately, but there are still many discrepancies and missing tags. So I thought I might try to do some planning instead of always improvising, une fois n'est pas coutume. And I'll practice my English, too, and learn more about Markdown.

The references:

The rules :

  1. Work on subway lines 1 to 9. Whether other lines should be dealt the same way might be discussed later.

  2. Every existing railway=station node that corresponds to a subway station should also be tagged as public_transport=station, subway=yes and (if it's only for lines 1 to 9) station=subway. Reciprocally, any public_transport=station should be tagged the same way if it corresponds to a subway station.

  3. Existing nodes should not be moved unless really necessary (i.e. do not apply the "This node should not be part of a railway track" rule for an existing railway=station node, unless I am ready to really map a public_transport=stop_area relation for that station).

  4. Only one railway=station node should exist for every subway station, unless it is used for very different networks (lines 1 to 9 will be considered as one single network, I may let several railway=station nodes if they exist in multi-network stations such as 서울역, but I'm not sure about that).

  5. Every existing public_transport=stop_position node in the subway network should be tagged as subway=yes and be located on a railway=rail or railway=subway way. It should not be tagged as railway=station or station=subway.

  6. All the public_transport=station nodes that belong to the same line should be members, with no role, of the relation(s) associated with that line. These relations may follow the new Public transport proposal (i.e one relation for each direction or branch) or not.

The planning:

Subway stations

  1. Select all railway=station and public_transport nodes in the Seoul Metropolitan area using the following Overpass request:

    out meta;
  2. Load these nodes into a JOSM calque (ça se dit comment, en anglais?). Also load in another calque the railway=subway and railway=rail ways in the same area:

    out meta;

    and/or maybe load in another calque the relation that corresponds to each subway line:

    out meta;
  3. For each subway station:

    • add the required tags for the corresponding station node;
    • remove the duplicates if any;
    • add the node to the relation associated to the subway lines this station belongs to (do it for each subway line separately):

      out meta;

Stop positions

  1. Load in JOSM the public_transport=stop_position nodes (maybe only if they are not too far from subway stations):

    out meta;
  2. Add subway=yes for those which are located in a subway station, and move them onto the railway=rail or railway=subway way if necessary.


  • set railway=subway for all railway=rail ways associated to a subway line?

  • create public_transport=stop_area relations for every station? At least for those with at least two public_transport=* nodes ?

  • apply the following railway_station rule:

    Using the word "station" in the name=* if it is not part of the name printed on signs at the station, i.e. avoid name=Station Newton

  • make the subway map look pretty for (I know, don't map for the renderer. Anyways, if I can apply the rules and make the renderer happy, there's no harm.)

Bon, personne n'a lu jusqu'ici, mais 괜찮아, c'est d'abord pour moi que j'ai pris ces notes.

Situation géographique de TRADEX S.A.

Posted by jaymee126 on 26 March 2015 in French (Français)

Il m'est paru nécessaire de situé sur une carte libre les endroits que je fréquente. Et pour commencer : l'entreprise pour laquelle je boss.

Les services de Tradex S.A. se trouve dans deux bâtiments bien distincts. Ils se trouvent dans la même rue mais distant d'environ 500 mètres. La Direction Générale est bien situé sur la carte. Il ne reste plus que le deuxième bâtiment qui abrite la Direction Commerciale en particulier.

Counting cross-border roads

Posted by Julien Brault on 25 March 2015 in French (Français)


I would like to count the number of roads crossing a national border in Europe. Obviously this would take a long time to do by hand. Do any of you know of a way to do this in some kind of automated way ? Or know any trail which could show me how to do it ? With OpenStreetMap or through other ways ?

Thanking you in advance,

Julien Brault

Il y a plusieurs milliers de nodes orphelins a Charlotte en Caroline du Nord. J'ai entrepris d'ajouter les ways manquants avec fusion des noeuds orphelins existants avec josm. J'effectue cette "mise a jour" par zone (il y en a 15). Apres j'effacerais les nodes orphelins restants. C'est un travail de fourmi que j'estime a un mois ?

Running for the 2015 HOT Board

Posted by PierZen on 16 March 2015 in French (Français)

My journey at OSM / HOT

The Haiti Earthquake in january 2010 let me discover what it was possible to do remotely to support humanitarian actions. I jumped in rapidly and used my various skills to support this first HOT activation. I remember these updates where we saw first Schuyler and Tom Buckley and then Nicolas Chavent and Robert Soden in action, the interviews in the tents, the HOT kits, the workflows built with the UN agencies.

On the steps of these initiators of HOT Activations, I started at the end of 2012 to coordinate a serie of major activations where the core coordinators we supported remotely the international community. With the rebellion in the Kivus, north of the Democratic republic of Congo, hundred of thousands of people were fleeing on the roads. Nicolas who had worked previously for the UN Agencies (WFP and UNJLC/Log-Cluster at inter-agency level) organized the contacts with OCHA and asked Claire to assure the liaison from Kinshasa.

We had the objective to professionalize our activations, to gain confidence of the various international organizations and convince them to collaborate with OSM and HOT, to make OSM the Reference map in the context of disasters.

In parallel of the Congo Activation, I started The Mali activation two months later. Andrew Buck then joined in and Severin started activations for the Central Africa Republic (CAR) and South Sudan. At the same time, Jorieke and other Eurosha volunteers in CAR had to move out rapidly because of the insecurity.

With the Activations, the support of local communities and discussions, collaborations with the Red Cross, MSF, Eurosha, Espace Francophone projects, a place of innovation and experimentation was gradually implemented. We also proposed Design improvements of the Task Manager to adapt it to the context of Activations, offered various Daily exports, looked at using mobile devices for data collect, contributed to software experiments, design, development.

The core coordinators, we volunteered to develop gradually this model of activation that showed such success for the Ebola Outbreak response. We documented the wiki project page for each activation, advertised the OSM maps & products, assured daily updates of various exports, documented the Task Manager Jobs and negotiated for constant adaptations of this tools that is central for supporting these remote activations through internet. Jean-Guilhem Cailton and Fred Moine were also very supportive and reactive about imagery processing.

We assured the remote response mapping, obtaining the imagery from various Imagery providers, coordinating with the international organizations, convincing sometimes the developers to adapt their tools to the particular context of our activations. I bloged and emailed regularly on the activations on the hot website and the mailing list and participated to international conferences making outreach about our activities.

In parallel with the activations, we also worked to innovate in data collection and technical remote support of local communities. We also established contacts with the Red Cross and MSF, discussed about ways to progress. This was later beneficial for the Haiyan/Yolanda Activation in november 2013.

For the Mali Activation in early 2013, we implemented an Imagery Crowdsourcing application to have the capacity to spot villages spread in either flooded or desertic areas and difficult to view. Pierre Giraud adapted the Tasking Manager to import the polygons of the various residential areas. This helped focus around the villages, locate and trace the highways connecting to these villages.

The Haiyan typhoon that hit Tacloban city in november 2013 was very destructive and cut all communications and electricity. Our Red Cross partners were waiting to deploy in Tacloban, not knowing what was the exact situation on the ground. The international community was rapidly mobilized, satellites re-oriented to obtain post-disaster imagery. OSM, Copernicus and UNOSAT did Post-disaster evaluation to facilitate the logistic of the organization.

For that Activation, we coordinated with Maning Sambale (HOT/OSM Philippines) who managed discussions with the local governments about Opendata and interacted with the government and the international agencies and mobilized the OSM-Philippines. We had a very effective coordination with the American Red Cross, the UN agencies and the international organizations.

The first 10 days of the activation were impressive with the OSM developers adapting the Humanitarian style to show damages to structures and adding this style to various tools. This was quite a satisfaction 10 days later for all of us to see the Poster size maps delivered to the OIM at Tacloban airport. This is crisis response, with a lot of adaptation, listening, innovation.

In 2013, participating to a training mission in north of Haiti and to the Espace Francophone LearnOSM translation sprint, was the opportunity to be confronted with the field reality, the cultural context and the technical challenges we are faced in such missions. Very satisfactory experience with great friends. This is the type of experience we should give the opportunity to the more engaged volunteers of our organization, to help them progress and adapt to the reality of the various countries where we operate.

My 2014 HOT Journey

The Ebola outbreak in Guinea spread rapidly in march 2014 and for the first time in urban area and large territories. In the context of epidemics, the contact tracing is a crucial operation. MSF epidemiologists were faced with blank maps. Village names were an other problem with duplicates or variants. Looking at the Haiyan experience, they thought that GIS support and OSM maps would be beneficial to this response. CartONG GIS specialists worked in the field with the epidemiologists and had coordinating with HOT. The first imageries were bought by MSF and the OSM response was simply fantastic, three cities being mapped in one day. Rapidly the Red Cross joined in, HIU, MapBox and Airbus Space & Defense also provided free imagery. Volunteering over all of the last year for this Ebola response, was for me and surely for others both challenging, sad with the spreading of the epidemic, these continuous deaths with this very complex epidemic. But at the same time this was rewarding looking at what we can accomplish in such circumstances, how we can progress to coordinate with other organizations and make the difference. After Haiti, the West Africa Ebola activation is a reference, not only for the more then 15 millions objects edited and the 3,000 contributors from more then 100 countries, but also for the efficient of collaboration we implemented with UN Agencies and international organizations.

My vision of HOT

This is a year of transition in the HOT organization with the majority of the Board of directors not renewing their term and the executive director announcing this week her departure. Thanks to all for their contribution to this organization.

Many of this year Board Candidates have significant experience and engagement with HOT, either on the Board mounting projects, interfacing with the partners. While we discuss for this election, I am convinced that the previous Board, the Executive director and the Board candidates can sit together and plan a smooth transition, assuring that the essential informations are transferred to the new Board and that we maintain the momentum of HOT.

Now that the nomination period is closed, the HOT membership will continue privately the discussions about orientations of HOT. I hope that this will be done with respect and openness. These annual meetings are also to review our processes, to question and assure that we adapt smoothly, that we assure to stay dynamic, motivated and innovative. Accountability, Openness, Respect are for me essential values in an organization like HOT with a mix of passionate and engaged volunteers, contractors and paid staff from which we benefit expertise. We have to be careful to offer a place of discussion where members can recognize themselves.
To meet once a year to select a Board is not enough. The new Board should look at how the information circulate better, the expertise of the membership is more effective to orient the projects. We should interrogate ourselves how the Working groups or other participation channels can facilitate the HOT operations with more connections between the volunteers, the contractors, the ED and the Board.

With the complexity of projects running, the share of expertise among members, the development of internal capacity in organizations like HOT is an essential factor of success. HOT is an organization with technical people having expertise in various sectors. We interconnect with various UN agencies and international organizations both to develop softwares, projects, collect field data, discuss about building information systems, collecting data from various governments and organizations. Organizations like HOT with both paid staff, contractors and volunteers should not be thought only as a hierarchical structure with the Board, the executive, and the contractors. There are surely confidential matters that should be dealt only by the Board and the ED, but we need to bridge from the various projects. It is essential to assure skill transfers and revise the actual rules of governance. We should take care to have the mechanisms that assure the relay of information from one to the other, and the capacity to revise our projects if necessary and assure a constant progress in this context of innovation and complex organisations sharing work with the the international organizations.

Let me take the example of an activity I was quite involved over the years with HOT. Since the start in 2010, the Activations offered our community the possibility to identify a clear space where we can collaborate with international organizations, innovate and have a significant impact mapping to support their deployment. As one of the core Activation coordinators since 2012, I am proud of the model we developed coordinating with UN Agencies and international organizations. We need to consolidate this action, by adapting the softwares to the needs of the activators and progress with our partners in field data collection. Tools like ODK can favor more exchanges between the humanitarian organizations and OSM. We can say that as volunteers for the OSM Ebola response in 2014, we impacted positively the organization. This opened doors for more collaboration and facilitated access to resources such as the 200,000 USD donation by the Hewlett Foundation, all of these allowing to deepen the impact of remote HOT crisis activations for both Humanitarian and Development actors as well as local communities.

I agree with Jorieke saying that the heart of HOT is this community and that the Board actions should not be isolated from the community and with other candidates that say we should do more community support and preparedness.

I also agree with Severin and Nicolas vision about how to reinforce this member-based organization with a more transparent organization.

We need also to identify clear objectives how the various activities may globally make the difference with common objectives about obtaining OpenData necessary to have more accurate maps. They should be integrated with a vision of which informations are the more crucial in the context of disaster and for economic development in general. Territory management by local authorities or by the international organizations supporting in case of disaster need solid Opendata about infrastructures and administrative limits. Obtaining such Opendata from various governments is often uneasy. But more we develop interelations with OSM local communities, universities, local government, more we will progress to answer these questions. For the Haiyan Typhoon response in november 2013, I saw how useful was the OSM community with Maning Sambale coordinating with the remote coordinators and interfacing locally with the international agencies and local governments.

HOT is an innovative organization that has multitude interactions with other organizations. The Board, the Executive, the contractors and the volunteers all have significant expertise and assure the progress of HOT in interaction with the UN Agencies and international organizations. We should assure a synergy of these various parts of HOT, reinforce the participation of the volunteers and contractors to project design, orientations, discussions with partners, evaluations. This to assure that we progress both with innovative products and projects, this in complex environments in interaction with our various partners.

We need Board directors willing to work with this community in a less hierarchial organization, discuss orientations, the progress of the projects, and assure the development of the organization.

We do not need to change fundamentally the structure of the organization, but to assure more bridges between the Board, the Executive and the membership, be more accountable, more open to discussions. If we can have more possibilities for the engaged members to participate to some field missions, this should also be quite a motivator. These are conditions that should favor the membership participation, more exchanges and assure constant innovations in the organization.

How I can play a role on this Board

I have previous experience as a Board director and managed the major activations since 2012 interacting with various organizations.

My grounding to the various realities of HOT action, my involvement both in action, organization, innovation, development, the support to both the humanitarian organizations and local communities, gives me the capacity to evaluate, orient projects, discuss with partners and the community. My experience in the various sectors of activity of HOT and dealing with partners is an asset for the organization.

In this year of transition, we need experienced people in the field of activities of HOT with a vision of the organization progress, pragmatic, able to sit both with the partners and the community, to continue in the action like we ever did.

HOT is a techy volunteer organization I am proud of and that I want to assure it will progress well.

Le samedi 14 février 2015, cartopartie sur le thème des charbonnières à Combas

Posted by Amélie on 12 March 2015 in French (Français)

Le Collectif des Garrigues, en collaboration avec le Collectif du Bois des Lens et Altimara, a organisé une journée d’échanges sur le territoire du bois des Lens à Combas, autour de la cartographie participative sur le thème des charbonnières.

L'objectif de cette journée était de partir sur les traces d'Emilie et Roland Bonnaud, qui ont réalisé en 2012, un inventaire considérable des charbonnières, mais aussi des fours à chaux et des capitelles présentes sur le massif du bois des Lens.

Une trentaines de personnes étaient présentes samedi 14 février, afin de découvrir ce patrimoine sur le terrain, mais aussi de compléter la carte de bois des Lens en vérifiant le positionnement GPS des relevés d'Emile et Roland Bonnaud, tout en réalisant la trace des sentiers de promenade et en essayant de localiser de nouveaux objets.

Nous nous sommes organisés en cinq groupes. Les trois premiers sont repartis dans la Combe des Chêvres, le ruisseau de la Combe du Duc et le ruisseau de la Font du Bayle là où Emile et Roland Bonnaud avaient déjà fait leurs relevés GPS. Un quatrième groupe a décidé de s'élancer en plein bartas, dans la Combe de la Réserve, à la recherche de nouvelles charbonnières. Un dernier groupe, est resté dans le village, pour relever le plus de patrimoine possible.

Ces relevés des sites charbonnières s'intègrent dans la mise en place d'un inventaire du patrimoine vernaculaire des garrigues. Une carte répertoriant les sites charbonnières, fours à chaux, capitelles... est en cours de création. Les participants de cette journée ont appris à reconnaître une ancienne charbonnière et peuvent participer à cet inventaire.

Une rétrospective de cette journée a été présenté le dimanche 08 mars, lors du festival Lo Garou à Sainte-Croix de Quintillargues, Avec ce beau temps, de nombreuses personnes sont venues découvrir le travail du Collectif des Garrigues sur la cartographie participative. Nous avions le stand le plus connecté du festival !

Cartes Vertes et Environmental OSM (découverte du jour)

Posted by EddieJ on 24 February 2015 in French (Français)

Je me repenche sur la question de l'utilisation d'OpenStreetMap pour servir des projets liés à "l'Environnement", en particulier des choses relevant des "Cartes Vertes".

Je viens de découvrir la page Environmental OSM sur le wiki OpenStreetMap

Environmental OSM is an attempt to provide OpenStreetMap tools to help tackle global warming, sustainable development and biodiversity. OpenStreetMap is proving to be an invaluable tool for a wide variety of projects & industries throughout the world and it also has the potential to help many environmental projects.

Dans l'esprit de cartographie des liens et dispositifs télécoms visibles (antennes,support de ces antennes) ou non (faisceaux, fibres, liaisons cuivre) je propose de cartographier quelque chose de bien visible cette fois que sont les PMV (Panneaux à Message Variable) qui l'on trouve notamment sur les autoroutes. Cela peut faire partie des "road signs" pour lesquels il y a un projet de cartographie belge. Mais rien n'existe pour les PMV. Cela peut toutefois être pertinent pour les automobilistes afin de savoir où se situe le point d'information (les PMV sont destinés à informer les usagers en temps réel) le plus proche en aval de leur route et ce, dans la perspective d'un autoguidage. Ces dispositifs sont stables spatialement et dans le temps étant donné qu'ils sont placés en général sur des portiques. db

Propostion transports en commun

Posted by Virgile1994 on 7 February 2015 in French (Français)

J'ai "enfin" réussi à mettre sur "papier" mes idées d'amélioration des transports en commun. Ça se passe sur le wiki.

Aussi, petit bilan de mon travail depuis la dernière fois : mise à jour du réseau TAG en septembre 2014, réseau ruban (agglomération Bourgoin-Jailleu, L'Isle d'Abeau), lignes SNCF Lyon-Marseille et Tram-Train de l'Ouest Lyonnais. Je commence à m'attaquer au réseau L'Va (Agglomération de Vienne)

Au passage, mon travail à Grenoble sert ! D'une part, l'agglo s'en sert pour MetroMobilié (application mobile - pour l'instant qu'Androïd - et site web), et Kyro38 s'en sert aussi pour son appli Grenopolitain (appli iOS)

Actuellement je mappe sur une commune du BENIN. Mais, je suis confronté à un problème. Je cartographie les rues, routes et bâtiments dans la commune de Cobli situé dans le Département de l'Atacora. Le problème est qu'il y a deux versions d''imagerie fournies par Bing: Une ancienne et une nouvelle. Lorsque je zoom, j'ai l'ancienne imagerie. En revanche, avec la nouvelle version d'imagerie, le niveau de zoom ne permet pas de bien digitaliser les objets car trop petit pour dessiner leurs contours. Bon je ne sais quoi faire. Mais en attendant, j'utilise l'ancienne imagerie. Ce qui n'est pas à mon avis pragmatique d'autant plus que sur la récente imagerie apparaissent de nombreux objets à ajouter dans la base de données OpenStreetMap. Que faire?
