HOT Voting Member Nomination

Posted by mingo23 on 7 February 2017 in English (English)

Dear HOT members,

my name is Marco Minghini and I come from Como (Italy). First of all, I wish to express my gratitude to Cristiano Giovando for suggesting my name for HOT membership. I would be delighted to become part of such a great community.

I have carried out my studies in Environmental Engineering (specialization in Geomatics and GIS) at Politecnico di Milano, where I obtained a BSc in 2008, a MSc in 2010 (both with honours) and a PhD in 2014. Since then I am working as a Postdoctoral Research Fellow at the GEOlab (Geomatics and Earth Observation laboratory) of Politecnico di Milano in Milan (Italy).

I am passionate about open source software, that I use everyday in my research activity, and enthusiastic of open data. Since 2015 I am a Charter Member of the Open Source Geospatial Foundation (OSGeo) thanks to the contribution I have given in the education, promotion and development of open source geospatial software and open geodata. Despite knowing the OpenStreetMap project since my MSc studies, it was only thanks to my PhD research (focused on Volunteered Geographic Information and Citizen Science) that I really started to study the project, to understand its evolution and impact, to analyse its applications and to use its data. After almost three years since then, I have become an experienced researcher on OSM, particularly on topics such as OSM data quality, OSM contribution patterns and contributors' motivations, and exploitation of OSM data to derive concrete products like land use and land cover maps.

Soon after my first OSM edit in 2014 I discovered the impressive work of HOT and I started devoting my time as a volunteer of this network. In addition to being a proud humanitarian mapper, over the last couple of years I have been supporting HOT and Missing Maps through the organization of mapathons at Politecnico di Milano (e.g. after the earthquakes in Nepal in 2015 and Ecuador/Japan in 2016) and the provision of support/training to different communities. When organizing these mapathons I had the plasure to know and to personally interact with Tyler Radford and Cristiano Giovando (who gave an exciting live skype call during our event for OSM GeoWeek 2015) as well as Blake Girardot, who often setup customized mapping projects for us. In particular, the kinds of events I am most proud of are the so-called "minimapathons", that are mapathons for primary school children. Notably, in March 2016 my colleagues and I organized a successful humanitarian mapathon by involving 200 10-year old students in mapping buildings for a project on malaria in Swaziland (see this post on HOT's blog).

I am also an active promoter of HOT and its activities among my research and professional network. As an example, as the responsible and point of contact of GEOlab for the GeoForAll network, in 2016 I gave a webinar on how to organize a humanitarian mapathon. I have also promoted humanitarian mapping at national events, for instance the 2016 conference of the Italian OSM community (OSMit 2016). In few days (on Friday, February 10) I will give an invited speech on "OSM for emergencies" at OSMit 2017, where I will present the activities of HOT and focus on the mapping effort of the Italian community after the terrible earthquakes occurred in 2016.

Finally, some students at Politecnico di Milano have recently found PoliMappers, an official student association which became the first European node of the YouthMappers network. I was proud that they asked me to become the Faculty Mentor of this association. The activities planned include both field mapping and remote mapping on HOT's tasks and I have already given some tutorials on how to use OSM mapping tools (until now iD, JOSM and Field Papers). Finally, last year I made my first donation to HOT as I really believe in the value of its activities.

With no doubt I will continue to support HOT in 2017 and beyond. In particular, as I have just become the Secretary of ISPRS WG IV/4 “Collaborative Crowdsourced Cloud Mapping (C³M)” as well as a member of the new EU COST Action CA15212 “Citizen Science to promote creativity, scientific literacy, and innovation throughout Europe”, I plan to make more and more people in these networks aware about the potential of humanitarian mapping using OSM. Thanks to the collaboration with PoliMappers, I will of course continue to organize humanitarian mapping events and provide the required training and support. Finally, depending on the time required, I would like to start being involved in one of the HOT Working Groups – perhaps the one on Training.

My OSM username is mingo23 and my Twitter profile is @MarcoMinghini. Here you can find an updated list of all my activities (such as events organized and papers written) related to OSM.

Thank you very much for your attention and for considering my nomination. Best regards and happy mapping to everyone!

Why I would like to join HOTOSM

[EN] Why I would like to join HOTOSM

It was short time after Nepal earthquake when I understood and measured the power of mapping, what it could do to support people in need and how open mapping could be saving lives. I start gathering with a small group of mappers is Mexico City who got together every Wednesday evening, I wanted to learn and see what else could be done. In State of the Map US 2015 with my colleague Andres Ortiz we presented “When will Mexico be navigable on OpenStreetMap” working in a technology company, Telenav, helped us to get resources to start improving the map from the roots, we started an import project to improve the Administrative boundaries of the country going from 69 valid boundaries to 2,457 . After that conference in New York everything started moving faster. In September 2015 the 30th anniversary of Mexico city earthquake took place, the National Digital Strategy Office of the Government of Mexico in the one Rodolfo Wilhelmy was Open Data Director at that time invited me to help with part of the coordination having a Earthquake drill and making different Government entities to understand the value of Open Mapping. Thanks to the experience we gained as a community with the Earthquake simulation, at the time Hurricane Patricia was about to hit the Pacific Coast of Mexico, more than 500 mappers helped to map the area in less than 48 hours following the example from Nepal. All this community efforts were mentioned in the Internet day by the President of Mexico mentioning how HOTOSM volunteers supported this national emergency.

Along with members of the LatAm and Mexico community I engage in every conference and every workshop the importance of Humanitarian Mapping and how we can improve people lives and to have a response not only after disaster but also considering long term projects in the ones we can work together with Governments and Civil Society to reduce disaster damage with the support of maps. I gave a talk in HOT summit last year named “Future of Humanitarian Mapping in Mexico” mentioning all these topics.

I feel very honored that friends like Humberto Yances and Rodolfo Wilhelmy contacted me to see if I could be interested in being a HOT member, without hesitating I told them it is a recognition I will be grateful to have. One of the opportunities I would like to focus with the National Center for Disaster Prevention of Mexico is to teach its officials how to map and create an internal group of trainers as a sustainable guarantee. The National Digital Strategy office mentioned they are very interested in support this initiative starting to map the temporary shelters and then mapping a pilot potential risk area that can show results and motivate more regions.

At this moment most of HOTOSM successful histories are in Africa and Southeast Asia, I am convinced my contribution to the organization can help to create more successful histories in other parts of the world so we can mitigate together the damages caused by disasters and create effective protocols for emergency management.

[SP] Por qué me gustaría ser parte de HOTOSM

Poco tiempo después del terremoto de Nepal fue cuando comprendí y pude medir el poder del mapeo así como ver lo que se podría hacer para apoyar a las personas necesitadas y cómo la cartografía abierta y participativa podría salvar vidas. Empecé a reunirme con un pequeño grupo de mapeadores en la Ciudad de México que se reunían todos los miércoles por la noche, quería aprender y ver qué más se podría hacer. En State of the Map 2015 con mi colega Andrés Ortiz presentamos "¿Cuándo será México navegable en OpenStreetMap", al trabajar en una empresa de tecnología, Telenav, nos ayudó a obtener recursos para comenzar a mejorar el mapa desde la raiz, comenzamos un proyecto de importación para mejorar las límites administrativos del país que solamente tenía en ese momento 69 límites válidos y lo mejoramos a 2,457. Después de esa conferencia en Nueva York todo comenzó a moverse más rápido. En septiembre de 2015 tuvo lugar el trigésimo aniversario del terremoto de Ciudad de México, la oficina Nacional de Estrategia Digital del Gobierno de México en la que Rodolfo Wilhelmy fue Director de Datos Abiertos en ese momento me invitó a ser parte de la coordinación de un simulacro de terremoto y de esa forma hacer que diferentes entidades gubernamentales entiendan el valor del Open Mapping. Gracias a la experiencia adquirida como comunidad con el simulacro del terremoto, cuando el huracán Patricia estaba a punto de llegar a la costa del Pacífico de México, más de 500 voluntarios ayudaron a mapear el área en menos de 48 horas siguiendo el ejemplo de Nepal. Todos estos esfuerzos de la comunidad fueron mencionados en el día de Internet por el Presidente de México en el que comentó cómo los voluntarios de HOTOSM apoyaron esta emergencia nacional.

Junto con miembros de la comunidad de LatAm y México cada vez que tengo la oportunidad de participar en conferencias y talleres siempre comparto la importancia del mapeo humanitario y cómo podemos mejorar la vida de las personas y tener una respuesta no sólo después de la catastrofe sino también considerar proyectos a largo plazo en los que podemos trabajar juntos con los gobiernos y la sociedad civil para reducir el daño que pueden causar los desastres con el apoyo de mapas. Di una charla en la HOT Summit el año pasado llamada "El futuro del mapeo humanitario en México" mencionando todos estos temas.

Me siento muy honrada de que amigos como Humberto Yances y Rodolfo Wilhelmy me contactaron para ver si estaba interesada en ser un miembro de HOT, sin dudar les dije que sería un reconocimiento que estaría honrada de obtener.

Una de las oportunidades que me gustaría desarrollar sería con el Centro Nacional de Prevención de Desastres de México en el cual se podría enseñar a sus funcionarios cómo mapear y crear un grupo interno de formadores como una garantía sostenible. La oficina de Estrategia Nacional mencionó que están muy interesados en apoyar esta iniciativa comenzando a mapear los refugios temporales y luego mapear un área de riesgo latente como prueba piloto que pueda mostrar resultados y motivar a más regiones.

En este momento la mayoría de las historias exitosas de HOTOSM se encuentran en África y el Sureste de Asia, estoy convencida de que mi contribución a la organización puede ayudar a crear más historias exitosas en otras partes del mundo para mitigar juntos los daños causados por desastres y crear protocolos eficaces para la gestión de emergencias.

[FR] Pourquoi je souhaite faire partie de HOTOSM

Peu après le tremblement de terre au Népal, j'ai compris et mesuré le potentiel de la cartographie, ce qu'elle peut faire pour aider les gens dans le besoin et comment la cartographie ouverte peut sauver des vies. J'ai commencé à me réunir avec un petit groupe de volontaires de la Ville de Mexico qui se réunissait tous les mercredi soir, je voulais apprendre et voir ce qui pouvait être fait. Lors du State of the Map US 2015, avec mon collègue Andres Ortiz, nous avons présenté "Quand le Mexique sera-t-il navigable sur OpenStreetMap". Travaillant dans une entreprise technologique, Telenav, nous avons pu obtenir des ressources pour commencer à améliorer la carte depuis les bases, nous avons commencé un projet d'importation pour améliorer les vecteurs des frontières administratives du pays allant de 69 limites valides à 2457 . Après cette conférence à New York, tout s'est accéléré. En septembre 2015 a eu lieu le 30è anniversaire du tremblement de terre de la ville de Mexico, le Bureau National de Stratégie Digital du Gouvernement du Mexique dans lequel Rodolfo Wilhelmy était Directeur des Données ouvertes, m'a invitée à aider avec une partie de la coordination avec un sondage et faire en sorte que différentes entités gouvernementales comprennent la valeur de l'Open Mapping. Grâce à l'expérience que nous avons acquise en tant que communauté lors de la simulation du tremblement de terre, au moment où l'ouragan Patricia allait frapper la côte du Pacifique au Mexique, plus de 500 volontaires ont aidé à cartographier la zone en moins de 48 heures suivant l'exemple du Népal. Tous ces efforts communautaires ont été mentionnés lors de la journée de l'Internet par le Président du Mexique en mentionnant comment les volontaires d'HOTOSM ont appuyé cette urgence nationale. Avec les membres de la communauté latinoaméricaine et mexicaine, je partage dans toutes les conférences et à chaque atelier l'importance de la cartographie humanitaire et comment nous pouvons améliorer la vie des gens et avoir une réponse non seulement après la catastrophe, mais aussi envisager des projets à long terme dans ceux où nous pouvons travailler en collaboration avec les gouvernements et la société civile pour réduire les dégâts causés par les catastrophes avec le soutien des cartes. J'ai donné un discours au sommet HOT l'année dernière intitulé «L'avenir de la cartographie humanitaire au Mexique» en mentionnant tous ces thèmes.

Je me sens très honorée que des amis comme Humberto Yances et Rodolfo Wilhelmy m'aient contactée pour connaître mon intérêt pour être un membre de HOT, et sans hésiter, je leur ai dit que c'est une grande reconnaissance. L'une des occasions que je voudrais mettre en relief avec le Centre national de prévention des catastrophes du Mexique est d'enseigner à ses fonctionnaires comment cartographier et créer un groupe interne de formateurs comme une garantie durable. Le bureau de la Stratégie nationale a mentionné qu'ils sont très intéressés pour soutenir cette initiative en commençant à cartographier les abris temporaires du Mexique, puis cartographier une zone pilote de risque potentiel qui peut montrer des résultats et motiver davantage de régions.

En ce moment, la plupart des histoires de réussite de HOTOSM sont en Afrique et le Sud-Est de l’Asie, je suis convaincue que ma contribution à l'organisation peut être de documenteer des experiences positives dans d'autres parties du monde afin d'atténuer ensemble les dommages causés par les catastrophes et de créer des protocoles efficaces pour la gestion des urgences.

Cokely Backcountry Skiing. Change set #45377916 by InfiNorth; approx Jan 21, 2017. Incorrect location of ski resort

Posted by Robert Copithorne on 7 February 2017 in English (English)

i would appreciate seeing comparisons of the area designated as abandoned ski resort, with the area designated cokely backcountry skiing. I believe their might be two areas, not one. If there are any old maps available to help resolve this issue, I would really like to see them.

I have an old brochure from the Mount Arrowsmith Ski Resort with a rough sketch of the ski trails, but nothing to tie the map in to. My view of the area I picked as a ski area fits the map better than the new area in my view. I can see how the new area could also be a ski area, but what distinguishes the areas?

Please reply as as I am anxious to resolve this issue.

Joining HOT

Posted by pratikyadav on 6 February 2017 in English (English)

I am PratikYadav and I work with Mapbox based in Bangalore, India. I came to know about OpenStreetMap and HOT after joining Mabox two years ago and been involved with both of them ever since. I started with taking part in the HOT projects where Mapbox team joins to help HOT in mapping and validation of various tasks over the year.From past few, month I have been working with HOT imagery coordination group to make sure the the request coming for imagrey can be quickly processed by Mapbox.

I worked with Mikel last year to understand the spatial spread of all past HOT tasks. 1

I am a big fan of HOT's work specially the concept of involving remote-volenters who are willing to help and link them to the people actually using these information on ground. My sepecific intrest this year will be to facilitate imagery coodination so that the most clear and recent imagery can be provided to mapping volenteers during crisis and how can we pre-identify and improve imagery coverage at hot spots. I talked about this last year at HOT summit (slides) and very excited to work with larger HOT team around this.

Fix for ‘Java-8 Will not Upgrade since Jan 2017’ under Debian Jessie

Posted by alexkemp on 6 February 2017 in English (English)

tl;dr: use the following from a console:

$ sudo apt install -t jessie-backports openjdk-8-jre-headless ca-certificates-java

JOSM needs Java-8. Open-Java-8 is available via Jessie Backports, but the current update (8u121-b13-1~bpo8+1) needs updated CA-Certificates which were not previously available from Backports (see Debian bug#851667). Unfortunately, Synaptic will not spot the updated certificates in Backports since it keeps holding back openjdk-8-jre, etc.. Thus, the need to use the console line as at top.

Unfortunately, I'd worked my way through the very-useful AskUbuntu question on:

“E: Unable to correct problems, you have held broken packages”

...and had therefore removed all Oracle + OpenJDK Java8 (which meant that all JOSM was also gone & all my Java alternatives reverted to Java7). However, it also meant that I had a different error message on attempted reinstall of Java-8:

$ sudo apt-get install openjdk-8-jre openjdk-8-jre-headless ca-certificates-java
  The following packages have unmet dependencies:
   openjdk-8-jre-headless : Breaks: ca-certificates-java (< 20160321~) but 20140324 is to be installed
  E: Unable to correct problems, you have held broken packages.

That allowed me to find a Unix Stack Exchange Q which solved the issue. Now I need to reinstall JOSM & make Java-8 the system default (sigh)...

When you 'discover' a city that is not on OSM

Posted by ff5722 on 4 February 2017 in English (English)

If you map in the West you may come to think that the major stuff in OSM is done, but in developing countries, you may discover major unmapped features.

Engaging High School Geography professors with OpenStreetMap

Posted by Mapanauta on 4 February 2017 in English (English)

Note: English [EN] please find the Spanish version below [SP]

[EN] Last week some members of the OSM Mexico Community had the chance to participate in the first OSM Training focused in Geography professors from High Schools located in municipalities close to the State Capital, Toluca. It was a four day event in the University of the State of Mexico. First Day It was the opening day and Edgar Lemus gave the Talk “Democratization of GIS OSM for high school education” making the professors aware about the importance of open source GeoTechnologies to get more involvement from the students and benefits in the societies. The second part of the event Edgar Lemus and myself gave the following topics to do a full immersion of the professors in the OSM world:

  1. What is Open Data? What is OpenStreetMap? What are the benefits of using OpenStreetMap?
  2. Humanitarian OpenStreetMap
  3. Mapping with ID Editor
  4. Mapping with HOTOSM Tasking Manager

Edgar Lemus presentando

Second Day The participants were previously warned the second day will be though but at the end of the day they will be knowing different tools they could use to adapt to current or future projects. So, it was a 100% mapping in the field day. Along with the professors it was decided to use every tool one hour so we could take advantage of the day out and then go back to the faculty to have pizzas for lunch (the mapper fuel!). We gathered at 9 am in Café con Leche restaurant (yes! It was added to the map) so at 9:20 we started it. a. Field papers We gathered in Los Portales an area very well located in Downtown Toluca. The previous day with the organizer Sandra Hernandez we defined an area easy for walking and divided it in four quadrants so we created teams, they will be responsible to cover the larger area as possible in one hour. The professors were very surprised to see the map and then compare it with reality. In average, each team added between 25-30 POIs in just a few blocks in downtown Using Field papers Picture-Using Field papers

b. OSM Tracker After using Field papers one of the professors asked “how can we be sure adding data manually with field papers will be exactly where it should be? So the answer was OSM tracker the next tool will give you a more exact location. We moved to a pedestrian street to capture the POIs and tracks and show them how to upload them to OSM. The professors were fascinated with the tools and we were just half the way. Banks, Convenience Stores, Restaurants, Pubs, Money Exchange among other were added to the map of Toluca. Tracks of OSMTracker Picture-Traces with OSM Tracker

c. Mapillary The first objective was to do a Mapeatón exercise in Downtown but the sidewalks and everything was so clean, organized and inclusive that the exercise migrated to do a walking exercise using two teams. Each team will be having three different phones so one could look forward, the second could look sideways and the third one could be looking backwards. The photomapping took place in a beautiful area with churches from the 18th century and gardens surrounded of history. Check the link so you can have a look.

Mapillary tracks in downtown Toluca Picture-Photomapping con Mapillary

d. OpenStreetCam After three hours of walking, we still had a tool to use, OpenStreetCam, but this time our feet were able to relax ;) because we used taxis to do the photomapping. Again field papers were used to print a larger area of Toluca downtown and divided in four, so four teams will be doing a photomapping of the assigned area. In one hour the teams had to go back to the Geography faculty and try to get the most tracks as possible in that amount of time. Toluca before Picture-Toluca Before

Toluca after Picture-Toluca After

e. Back in the faculty after the pizza break all the tools were showed in the screen so the Geography professors could have a broad overview of all the capabilities and how their own projects or student’s project could be having the benefit of OpenStreetMap

Third day El desbaste map a collaborator that mapped the city of Lerma and is working in the same Municipality as Chief of Design and Social Policy showed the professors how a city can be managed through all the Open Data generated by OpenStreetMap. How the city of Lerma has planned the trash collection using OSM data and even how citizens with economic difficulties can apply to social benefits. El Desbaste map showing the achievements in Lerma Also, the same day Beny Carbajal presented JOSM, Beny is a GeoInformatic graduated student who has been very active in OSM since the first Open mapping day last year and has been collaborating in HOTOSM activations, she is preparing herself to be part of the team who is sharing the OSM tools around Mexico. Beny presenting JOSM Fourth day After three intensive days, the professors defined a project in the one they will be using OpenStreetmap and the tools learnt to involve students and share the knowledge they just learned. Stay tuned for a blog from Sandra Hernandez in the one she will be explaining the projects and the results they are expecting in the High Schools of the State of Mexico


Formación de profesores de geografía en OSM

La semana pasada, algunos miembros de la comunidad OSM México tuvimos la suerte de participar en la primera Formación en OSM enfocado en profesores de geografía de Preparatorias ubicadas en municipios cercanos a la capital del estado, Toluca. Fue un evento que duró cuatro días y tuvo lugar en la Facultad de Geografía de la Universidad Autónoma del Estado de México.

Primer día.

El primer día Edgar Lemus (ealpv) dio la charla " Democratización de Tecnologías de Información Geográfica", el objetivo de esta charla es hacer los profesores conscientes de la importancia de geo-tecnologías de código abierto para conseguir una mayor participación de los estudiantes y dar beneficios sobre los datos obtenidos a las sociedades. La segunda parte del evento Edgar Lemus y yo participamos dando los siguientes temas para hacer una inmersión total de los profesores en el mundo OSM:

  • ¿Qué es Open Data? ¿Qué es OpenStreetMap? ¿Cuáles son los beneficios del uso de OpenStreetMap?
  • Humanitarian OpenStreetMap
  • Mapeando con ID Editor
  • Administrador de Tareas con HOTOSM

Segundo Día El segundo día estuvo dedicado a herramientas de campo. Los participantes estaban prevenidos que estaría pesado, sin embargo al final del día tendrían el conocimiento suficiente para utilizar diferentes herramientas adaptadas a proyectos futuros. Junto con los profesores se decidió dedicar una hora a la utilización de cada una de las herramientas y así aprovechar el día, posteriormente volver a la facultad a comer pizzas (¡el alimento preferido en mapatones! considerado el combustible para los mappers). Nos reunimos a las 9 am en Café con leche (sí! Fue añadida al mapa) y arrancamos el ejercicio a ls 9:20.

a. Field papers- Papeles en campo

Nos reunimos en el área de Los Portales, un área muy bien situada en el centro de Toluca. El día anterior junto con la organizadora Sandra Hernández definimos el área para poder caminar fácilmente, fue dividida en cuatro para crear equipos, ellos serían responsables de cubrir el área lo más que se pueda en una hora. Los profesores se sorprendieron mucho al ver el mapa y luego compararlo con la realidad. En promedio cada equipo añadió Entre 25-30 puntos de interés en sólo unas pocas cuadras en el centro de Toluca.

b. OSM tracker (Link Imagen del centro o Toluca) Después de utilizar Field papers, uno de los profesores preguntó "¿cómo podemos estar seguros que agregando datos de forma manual será ubicados exactamente donde deberían ser? la respuesta fue que la siguiente herramienta OSM Tracker le dará una localización lo más exacta posible. Nos mudamos a una calle peatonal para capturar los puntos de interés y las trazas, también se mostró cómo subirlos a OSM. Los profesores estaban fascinados con las herramientas y estábamos sólo la mitad del camino. Lugares como bancos, tiendas de conveniencia, restaurantes, pubs, casas de cambio, entre otros fueron añadidos al mapa de Toluca.

c. Mapillary Originalmente el objetivo era hacer primero es un Mapeatón (enlace a blog Ce) usando Mapillary pero afortunadamente las aceras del centro de la ciudad estaban limpias, organizadas e inclusivas. Por lo tanto el ejercicio fue modificado y se crearon dos equipos para hacer una caminata en el centro. Cada equipo tuvo tres teléfonos en diferentes posiciones, el primer miraría hacia el frente, el segundo miraría hacia un costado y el tercero estaría mirando hacia atrás. El fotomapping se dio a cabo en un lugar con iglesias del siglo 18 y jardines rodeados de historia. Checa el enlace para que puedas ver lo que hicimos.

d. OpenStreetCam Después de tres horas de caminata, todavía quedaba una herramienta por utilizar, OpenStreetCam, en esta ocasión nuestros pies tendrían tiempo para relajarse ;) ya que utilizaríamos taxis para hacer el fotomapping. Nuevamente se usaron field papers para determinar el área que se quería cubrir y en esta ocasión era de mayor cobertura y también fue dividida en cuatro, por lo que cuatro equipos estarían haciendo el fotomapping del área asignada. En una hora los equipos tratarían de conseguir el mayor número de trazas posibles para después reunirse nuevamente en la facultad de Geografía.

e. De vuelta en la facultad después del lunch se mostraron en la pantalla todas las herramientas para que los profesores de geografía tuvieran una visión general de todas las capacidades y cómo aplicarlas a los proyectos de sus estudiantes o a sus propios proyectos y así tener el beneficio de OpenStreetMap.

Tercer día

El Desbaste Map colaborador de OSM que llevó a cabo el mapeo de la ciudad de Lerma actualmente trabaja en el Gobierno de la misma ciudad como Jefe de Diseño de Política Social. El mostró a los profesores como se pueden aplicar políticas de gestión a través de los datos abiertos generados por OpenStreetMap, un ejemplo es cómo la ciudad de Lerma planea la recolección de basura a partir de datos de OSM y ciudadanos con dificultades económicas pueden solicitar apoyos sociales a partir de los datos.

Beny Carbajal presentó la herramienta JOSM, Beny es una estudiante recién egresada de Geoinformática, ella junto con varios estudiantes de la UAEMX han sido colaboradores muy activos en OSM desde que participamos en la 1ra Jornada de Mapeo Libre y también han estado presentes en activaciones HOTOSM, ella se está preparando para ser parte del equipo de talleristas OSM que está dando difusión a las herramientas de OSM por todo México.

Cuarto día

Después de tres días de intensa actividad, los profesores definieron un proyecto en la que van a utilizar OpenStreetmap y las herramientas aprendidas, estarán invitando a estudiantes a participar y compartir con ellos los conocimientos que acaban de aprender.

Estén pendientes del blog de Sandra Hernández en el estará explicando los proyectos de los profesores de Geografía y los resultados que esperan obtener en las Preparatorias del Estado de México.

Hi, I'm Elida!

Posted by uswatunkh21 on 3 February 2017 in English (English)

Hi, all. I'm Elida!

Thank you Joseph Reeves, for nominating me to be one of new HOT voting member. I am an Indonesian, and have been a member of HOT Indonesia since 2012 in a project entitled "Scenario Development Planning for Contingency Plan (SD4CP)" where OSM data were applied to generate realistic disaster impact to critical infrastructure. Up until now, I have involved in several activities related to HOT projects (SD4CP, POI Mapping, Bengawan Solo Mapping, Trenggalek Mapping, University Roadshow) -all of them are located in Indonesia- ranging from develop curriculum and training module, deliver training, arrange mapathon, and bring an end to end OSM data collection and usage for specific purpose -mainly in disaster field.

Activities during Bengawan Solo and Trenggalek Mapping

Since HOT is first place where I learned OSM, HOT means a lot to me. It allowed me to meet a new collaborative mapping tool, with huge potential use and the spirit of community empowerment. It also gives me opportunities to learn it from the masters, such as Kate Chapman and Joseph Reeves (thanks for introducing me to OSM) and also Russell Deffner and Mhairi O'Hara (thanks for teaching me HOT activation).

As a voting member, I want to be more actively involved in HOT decision making and share my ideas to meet the problems or challenges in the future.

I haven't been involved in HOT project outside Indonesia. But, in Indonesia, the biggest challenge related to either HOT or OSM, is the sustainability of the mapper (local mapper) to continuously map in OSM. I don't know whether this happens in other countries or not. To meet that challenge, I think we have to keep in touch with the mappers either online or offline, and encourage each other to keep mapping.

If you want to know more about me, I would happy to have a talk with you ! For further discussion, feel free to contact me using this email :

Dressed-up Notification Mails

Posted by saintam1 on 2 February 2017 in English (English)

I've started designing a new layout for OSM emails. I'd like to have feedback, and I need help with testing.


Like many websites, sends an email to members when something happens that concerns them. For instance, if someone comments on one of your changesets, you get an email. This is similar to how Facebook or LinkedIn send you a message when someone contacts you via their platform.

Unlike those websites, however, OSM emails look quite plain -- no colour, no layout, no logo. This must look disconcerting to new users. Good communication with new users is crucial, especially as we're seeing growing numbers of newcomers to the project who don't always engage in dialog with the community. More modern-looking emails can only help make the project look and feel more attractive and more legitimate to casual contributors.

Here are some screenshots of the new layout, click to embiggen.

Changeset comment, long Changeset comment, short Friend notification

You can help!

  1. Give feedback about the design in the comments below. There's still lots of room for improvement. Keep in mind that any new text has to be translated into dozens of languages, so ideally we should keep the wording as it is for now (no new text), and stick to modifying the presentation only.

  2. Take screenshots of what the new mails look like in your mail client. See the wiki page for details.

Implementation details are in pull request #1401.

POI standardization: Tractor Supply Co.

Posted by Jack the Ripper on 2 February 2017 in English (English)

I think it would be useful to people who simply use OSM data to have standardized, common values for POIs, in particular chain stores. I've come across lots of chains where individual stores have wildly varying tags (e.g., variations on the name, incomplete "shop" tags, etc.).

The purpose behind this note is to standardize the tags I will apply to Tractor Supply Co.

My standardized TSC tags:

  • addr:city={city name}
  • addr:housenumber={street number}
  • addr:postcode={zip code}
  • addr:state={state}
  • addr:street={road}
  • alt_name=Tractor Supply
  • building=retail (usually)
  • building:levels={as appropriate}
  • contact:phone=+1 {phone number}
  • contact:website=
  • image= {if available}
  • name=Tractor Supply Co.
  • official_name=Tractor Supply Company
  • opening_hours=Mo-Sa 08:00-20:00; Su 09:00-19:00 {as appropriate}
  • phone=+1 {phone number}
  • ref={store number}
  • shop=farm_supply; pet

new road

Just added a new road in princes town Trinidad... hoping it would be updated soon. satellite images out of date, but the road exists.

Location: Marcano St, Princes Town, Trinidad and Tobago

Using the Tofix plugin in the Tiger delta task

Posted by RichRico on 1 February 2017 in English (English)

Currently, many roads in the US are misaligned and out of date according to the satellite imagery, but also exists a bunch of missing roads that should be added and named according to the information provided by the Delta Tiger layer, which is updated until 2015. There were detected 126,981 errors in the cities of EE.UU, so to handle them we use OpenStreetMap Java editor (JOSM), which has some additional plugins such as tofix to solve errors detected in the tiger delta task.

We should install the JOSM plugin by going to the preferences icon, then to the plugin option icon where we search for tofix and finally, check the box and press OK.


Once tofix plugin is installed, we go to the windows menu to check the box of tofix, then the plugin panel will appear, so we can choose among the various options the tiger delta task, so we have a layer with purple lines that show the errors. As I initially commented, we use the tiger delta 2015 layer that we add by selecting it in the imagery menu. This imagery layer shows yellow lines on the map.


We should fix the street marked by the purple line by adding, naming or aligning the street. We have three options: * In case we fix the error, we click on the fixed button * In case there nothing to fix, we click on the not an error button * And if we are not sure where to fix or not, we can always skip it by clicking on skip button

I all cases, after clicking the button a new issue will be displayed, so we do the same process until hitting all the errors.

Uso del plugin To-Fix en la tarea Tiger delta

Actualmente muchos trazos de carreteras en Estados Unidos estan desalineados y desfasados según las imagenes satelitales y así mismo existen carreteras que faltan ser agregados y nombrados de acuerdo a la informacion que nos proporciona la capa del Tiger delta actualizado hasta el año 2015, para esta tarea se hizo las detecciones en la ciudades de EE.UU con un total de 126,981 errores detectados. Para realizar esta tarea utilizamos el editor de Java OpenStreetMap, éste editor cuenta con algunos complementos adicionales como los plugins el cual facilita en la ejecución de la tarea. En este post veremos el funcionamiento de un plugin llamado to-fix para solucionar diariamente los errores detectados en la tarea de tiger delta.

Para esto instalaremos el plugin de JOSM para esto no dirigimos al icono de preferences, a continuacion vamos a la opcion de plugin y buscamos tofix, seleccionamos y seguidamente le damos en OK.


Una vez instalado nos dirijimos al menu windows y marcamos con un chek en la opción tofix, seguidamente elegimos entre las distitas opciones la tarea del tiger delta en el tofix, después tenemos que agregar la capa del tiger delta 2015 el cual se distingue con unas líneas amarillas en el mapa. Así ya tenemos todo esta listo para empezar a solucionar todo los errores detecados.


Las líneas moradas no indican el lugar donde deberemos de dar solucion ya sea trazando, nombrando la calle o alineando. Después de dar solución le damos click en fixed. En caso de no existir un error le damos clic en not an error.

HOT Voting Member 2017 Personal Statement

Posted by dekstop on 1 February 2017 in English (English)

Thank you Ben Abelshausen for nominating me as a HOT voting member, and to Jorieke Vyncke and Harry Wood for additional support!

How did you become involved in HOT?

I have been aware of humanitarian mapping activities on OSM early on, but first really got to know HOT as an organisation through Kate Chapman's recorded talks. In 2013 I attended State of the Map in Birmingham where I met Ben and Jorieke, and learned about the growing range of development and aid activities that had grown out of the wider OSM network. In Summer 2014, a group of people started the first regular HOT mapathons in London (they would later co-found Missing Maps). I became an early participant, and my involvement grew from there.

Could you tell us about your involvement in HOT, mapping and/or humanitarian response?

I initially became active in HOT as a PhD student researching community organisations, and after some months of exploration decided to make HOT the centre of my work. Over the last 2-3 years I've gradually expanded my involvement. At some point during this time I also joined a growing volunteer team around Ivan Gayton, Pete Masters and Andrew Braye to help run their mapathons and other HOT-related activities.

My first tangible contribution is maybe the talk I gave at the first HOT Summit in 2015 (slides). I showed empirical evidence of some HOT community activities and outcomes, and discussed the implications. The talk resonated well, and sparked great debate during the session. Based on the feedback I got I think this helped people gain a different understanding of their work, and their priorities. (Unfortunately the video was never published, maybe we can get it online sometime.)

After the talk, Alyssa Wright approached me and suggested I should make my findings accessible to the wider community. This motivated me to start a research diary, where I now share findings from my various explorations of HOT activities. The first post discusses my motivation: to help develop a broader understanding of HOT through analytics and visualisations, contextualising the data, providing evidence to substantiate design choices, and offering conceptual models which help reason about HOT as a social phenomenon.

My research has progressed a lot since these early days, but most of the time it is still driven by a desire to use my research skills to support HOT as an organisation, and to inform and strengthen HOT practice. In addition, I've also been regularly approached by other community members with ideas about aspects to look at; have a look at some of my past diary posts for examples of this.

What does HOT mean to you?

My guest blog post for State of the Map 2013 ends with an observation that still motivates me today: HOT to me reflects a turning point in community technologies. It takes OSM as a starting point, but expands on it by connecting to a large universe of social concerns. In my opinion, a key contribution that HOT is making to the world is that it places community at the centre of its activities, and that it embraces and balances a multiplicity of perspectives. But also that it finds a delicate balance between a kind of volunteerism that is driven by enjoyment and personal enthusiasm, and an honest professionalism that connects to funding sources and places where "serious people" live. In that, HOT represents a rare synthesis of the lessons of open source culture and the aid and volunteering sector, hopefully managing to keep the best parts of each.

Why do you want to be a voting member?

I have experienced HOT from the "outside" for a few years now, and have become more and more personally invested in its future. I would like to formalise this relationship, and help take on the burden of making sure that it remains a healthy organisation for a long time to come.

As a voting member of HOT what do you see as your most important responsibility?

I think one of the most important contributions any member can make is their approach to internal discourse. I see it as my responsibility to promote things that I think are important, to alert the community of risks, but most importantly to do so in a manner that is constructive, never divisive, and to help moderate internal debates when emotion takes over.

How do you plan to be involved in HOT as a voting member?

I will keep up my enthusiasm for finding new HOT corners to explore, helping foster community engagement, seeking to help tackle community coordination challenges, and supporting daily practice in a range of ways. In addition, I look forward to participate in the governance of HOT. I have spent the last decade with a wide range of community organisations, and have had much exposure to the governance challenges they may bring, and some potential means of addressing them. I plan to bring this experience into my involvement with HOT, but also to come with an open mind, and to take time to listen.

What do you see as HOT's greatest challenge and how do you plan to help HOT meet that challenge?

HOT is attempting to foster a new kind of practice while the word is shifting around us. As a consequence, there is a long list of challenges. On top of that there are the challenges of a maturing organisation: managing funds, emergent factions, maintaining the tech. Others will have thought about these aspects quite deeply already. A personal concern for me is HOT's relationship to community growth, and community cohesion. Internally, and in its relationship to other organisations, and the wider OSM ecosystem. How large do we want to grow this? Do we have the means to deal with the consequences? I think there are many open questions related to this; but also a growing body of knowledge that we can draw from.

A Pride of Lions

Posted by alexkemp on 1 February 2017 in English (English)

Carlton & Nottingham love their Lions ([1] [2] [3] [4]) but I'm now mapping Gedling, and here is one of the latest photos of Gedling Church ([1] [2]), taken from near the top of Queen's Avenue, to prove it:–

Gedling Church view

Queen's Avenue is in the heart of Phoenix Farm Ward, and very close to the location of Phoenix Farm. The farm was demolished in 1954, just as the Estate named after it was being built (councillors, planners & builders love demolishing the old and building new estates) (one clue to the age of these houses is that they all have coal-holes).

The houses that I'm currently mapping all seem to have Royalty — and the then Royal Family in particular — as an (unannounced) theme:–

Stone Lions have so far proven to be as popular in Gedling as they were in Carlton, but I've resisted photographing them up to now. Finally, two in a house in Philip Grove persuaded me to add yet another photo of stone lions to this Diary:–

Removal of banner_url tags

Posted by BushmanK on 31 January 2017 in English (English)

At least some versions of editor (for example, MAPS.ME ios 7.0.4) have a bug, that makes it adding a banner_url= key with a value, that contains a shortened link to some pages, related to advertising system.

@Zverik (Ilya Zverev, OSMF Board member, who works for have assured us in his message on the Russian OSM forum, that it's a known bug and so on. However, nobody knows, how long some users will keep that buggy version and how long these tags will continue to appear.

Using a simple Overpass query and JOSM, I already have removed about two hundred banner_url= keys from objects, recently added or edited by users. It doesn't take much time, but I'm curious - is there a way to automate it and run a cleanup script, say, once per day?

Another question is more of a moral kind. Indeed, developers (@Zverik himself) have provided a supervision tool for changesets created by app. However, it puts the whole burden of supervision on volunteering mappers, while there is no way to reliably detect some anomalies automatically, it is understandable. But this exact case with banner_url= might not have a large impact (about five wrong tags per day), but it is known for a long time and for anyone familiar with a scripting language, it shouldn't take much time to develop an automated cleanup tool. But nobody of developers did that. That doesn't seem like a responsible manner of working with OSM data. Keeping in mind, how pushy @Zverik (as a moderator) is about being nice and respectful to others on Russian OSM forum, this situation seems like a significant hypocrisy.

Scaling the matching of Wikidata to OpenStreetMap with wikimama

Posted by BharataHS on 30 January 2017 in English (English)

The OpenStreetMap community has been adding wikidata tags to OpenStreetMap features for the last several months. Linking OpenStreetMap features to Wikidata can leverage both projects to create novel applications such as [multi-lingual maps](show link) and integrate other semantic information which OpenStreetMap doesn't have but Wikidata provides.

Till date, over 400K features have a wikidata tag. The integration of linking wikidata within iD and JOSM editors allowed mappers to efficiently map wikidata tags but the biggest challenge is to focus on the best match for cases when location or names do not exactly match.

This post will walk you through using wikimama, a tool to find and add missing wikidata tags in OpenStreetMap.

Matching Wikidata tags in neighborhoods with 'wikimama'

Let's say you want to get a list of all neighborhoods/suburbs within Stuttgart that don't have a wikidata tag and get a list of wikidata tag matches. The wikimama tool gives you this list that you can manually review and later add to OpenStreetMap.

  • Get the information of Stuttgart in OpenStreetMap

Stuttgart boundary in OpenStreetMap

We need the following information about Stuttgart: name, center longitude, center latitude, wikidata. Most cities in OpenStreetMap already have a wikidata tag, in case it doesn't exist, you can find it directly in (here's the wikidata entry for Stuttgart).

The boundary shows a radius of about 10 km will cover all neighborhoods/suburbs within Stuttgart.

  • Clone the wikimama repository from Github.

  • Prepare an input file to initialize wikimama. The input file needs the following:City, longitude, latitude, wikidata_id, radius, lookupdistance.

screen shot 2017-01-20 at 3 32 47 pm

  • Finally, run node batch-match.js --file input.csv.

  • Once finished, wikimama will produce an output.csv listing all neighborhoods/suburbs within a 10km radius of Stuttgart and the probable wikidata tag that matches each place.

  • Import the csv to a spreadsheet so you can do basic filtering and sorting. Use the JOSM url field to directly edit the feature in JOSM.

Output imported to a spreadsheet with basic filtering and formatting

What's under the hood?

Wikimama queries OpenStreetMap for all neighborhoods/suburbs within your defined threshold (10 km). This list of queried places are then compared to existing wikidata entries under the human settlement class/subclass. The matching compares both the geographic and Levenshtein distances for each entry and gives it a score of similarity. Higher score means a good match. Full description of the output csv is available in the repo's wiki.

To be clear, we are not proposing any automated upload of wikimama generated results to OpenStreetMap, Wikmama does not guarantee a 100% match for all queried places. This tool only provides a list of potential matches and scoring. The mapper should ultimately decide whether the match is correct and then upload to OpenStreetMap.

Our team at Mapbox have started using this tool to match wikidata tags in 20 cities and have linked for about 1,500 neighborhoods. If you need help in using wikimama or want a list of matches for your city, please comment here or directly in the wikimama repo.

Newcomers are welcome, even Pokemon Go mappers

Posted by rorym on 29 January 2017 in English (English)

Recently some players of Pokemon Go think that OpenStreetMap data is being used as data in the game, and by editing OSM they can force new things to appear in the game.

Some people don't like this swarm of newcomers, and rightly point out the bad, incorrect data that people are adding. Sometimes these newcomers are using Google Maps without a full understanding of what copyright is, and why that's not allowed in OSM.

I'm skeptical that Niantic are actually using OSM data this way. They may be using a static dump, but it's pretty rare for external, non-OpenStreetMap, companies to have a continuously updated database from OSM.

New users are always welcome, and if they are adding correct things, then I welcome them. It's always good to have new mappers, adding things for an area they are in. Pokemon Go is a game you play by going outside and walking around, so these people are adding data to their neighbourhood, which can often be better than remote mappers with no idea of the local area.
