Tweety Pie has moved to Valley Road

Posted by alexkemp on 17 August 2016 in English (English)

I was going stir-crazy & got back onto the road to do some field-work in Valley Road, only to discover this:

tweety pie in Valley Rd

(you may be more mature than me, but I found it funny; as a child I liked Warnor Bros cartoons way more than Disney)

I'm sorry to have to say that I found the 1930s detached & semi-detached houses in Valley Road & Prospect Road deeply boring. However, the residents were most helpful in helping me stem off dehydration by providing water + salt on request (both roads are on a hill & it was hot hot hot).

There were two interesting houses in Prospect Drive. This house board was made in Kenya:—

Every year Bangladesh is affected by the devastating natural and human-induced disasters . It is one of the most vulnerable countries because of the geographical location as well as meteorological characteristics. According to Country Disaster Risk Management Status Report 2016, during the 10-year time frame of the Hyogo Framework for Action (2005 to 2015), over 700 thousand people lost their lives and the total economic loss was more than $1.3 trillion. We all know that it is impossible to turn the scale of vulnerability into 0% but we can reduce the risk and vulnerability by merging with the new technology .The new dynamism of Open Street Mapping can create a huge difference by contributing to the humanitarian purpose . Open street Mapping is a free licensed mapping system , anyone can get free data for using the web -based mapping and anyone can edit the maps. With the collaboration of Dhaka City Red Crescent Unit (BDRCS) and OpenStreetMap Bangladesh community (OSMB), have arranged two days training for the students of Institute of Disaster Management and Vulnerability Studies. The main vision of this OSM training for the disaster management students was enriching their skills by using the open geographical data to identify the hazard , disaster , the vulnerability of any area , navigational and other humanitarian purposes . Moreover, the IDMVS faculty wanted to improve the capacity of the students, to do web –based map analysis instead of social mapping in their academic research. In 12 -13 August 2016 , the TOT (Training of Trainers ) on OpenStreetMap (OSM) was conducted at Lecture Theatre Building [First Floor] , University of Dhaka, Dhaka. This training was started from 09.00 am -05.00pm and it solely attended by the 20 students of Institute of Disaster Management and Vulnerability studies , University of Dhaka .

The training began with the presentation by Ahasanul Hoque as Geospatial data management consultant of World Bank Bangladesh. In this presentation, he presented the concept and the use of OSM data by showing all the activities around Bangladesh , especially in Disaster Management sector . After that , the training started with the practical session in which the participants practice their skill using ID Editor and JOSM mapping tools . This training led by Ahasanul Hoque and assisted by Sawon Shariar and Atikur Rahman Atik from OSM community Bangladesh.In this long Open Street Map training for two days has divided into many sessions .

#DAY 1 The first day of the training , the practical session divided into 2 sessions which were

----Introduction and the Use of iD EDITOR in OSM.

----Functions of Field Papers.

This practical session started with opening an account in iD editor , this web-based mapping tool always needed to be connected to the internet . Then all the students made their own OSM account by iD editor before the training began with its own enthusiastic wave . The participants were learned how to configure the background layer and how to do basic edit with iD editor along with knowing additional information and custom tags. Data that used in editing in this session was specially the home address of the individual participants .

After the lunch break , the participants were introduced to the Field Papers website . The participants were taught how to create a printable map atlas for anywhere in the world . They were learned how to print and add notes to the field papers. Moreover, as a practical implication , the participants were taken part in Fieldwork around the campus for using the field paper and marked the place which was shown in it

After the mapping party , they were come back to the training room and then upload the data from the snapshot by using the field papers website with the help of internet . The first day of the training session was ended with the horizontal development with the shores of knowledge as well as the fervent smiling faces of the participants .


The next day the training started with its full swing at the same place at the same time like the day before . The Second day of the training , the practical session divided into 3 sessions which were ---Introduction and the Use of JOSM in OSM.

---Introduction in HOT &Teach Tasking Manager .

---Map edit and upload related software and mobile apps.

In the second day of the training , the first session started with introducing JAVA Open Street Mapping (JOSM ). At first the training starting off, when all the participants already installed the java and then installed the JOSM . The training started with the basic knowledge of JOSM and then continued it with the basic editor and tags in JOSM . The participants were learned to use plugs in JOSM , activate imagery providers and upload data by using JOSM. After understanding how to run JOSM quickly , the participants were learned how to use JOSM offline by saving the important files for editing .

In the second session , the participants have instituted by the Humanitarian OSM Team collaborative mapping tool which is known as HOT Tasking Manager and Teach Tasking Manager . They were learned how to divide up a mapping job into smaller tasks that can be completed rapidly. The participants also used how to edit the maps both in teach and hot tasking manager not only editing by ID editor but also editing by JOSM. The data used in editing which was 215 DRM mapping in Kawakhola Union of Sirajgonj sadar upazilla and 2060 Peace Corps Malawi – Liwonde.

After learning the Tasking manager , the participants were introduced by many maps editing Mobile apps . The mobile apps are OSMTracker for Android , Map ME , Vespucci , Mapillary . But the most interesting part of that session was introducing the online Android game "Mapswipe' . Just by clicking every tap, the whole family during the disaster can be helped by putting it on the map through this game . The participants were fascinated by knowing the use of all these mobile apps and installed these games in their android phones .

The training was good . Even though there was not enough space to arrange these 20 participants but the passionate minds of the participants were enough to make them solving this tiny problem .From the beginning of the training, the internet connection that provided by organizer was commendable enough until the end of the training .

The main credit goes to this successful training , by the pioneer of OSMBD Ahasanul Hoque who has to widen the knowledge of the participants by introducing the new wisdom path through the enlightenment of web- based mapping tools. Special thanks go to the director of IDMVS , Dr. Mahabuba Nasrin for permitting the participants to use the IDMVS lab as the training room and encourage the students to implement the mapping knowledge in research . Moreover ,the assistant professor of IDMVS , Khalid Hasan who always appreciated the students to enrich them with the power of diversifying knowledge and help to arrange the whole training properly .

The participants also said that OSM is a great platform for them and it has some extraordinary useful concepts in the context of Disaster Management . They included that they will use this mapping tool during any kind of disaster-related research . Finally, the training was closed by the photo session between trainers and the participants .

Responding to suspicious changes

Posted by manoharuss on 17 August 2016 in English (English)

Following up on a recent series of posts that summarized the suspicious changes on the map, an interesting question that we bring to the community - what is a good amount of time to wait for a response from an inexperienced mapper before fixing or reverting their edit?

You can see examples of such changesets that do not seem right on these posts:

Observations from last week

  • User added unexplained nodes with alphanumeric names: 1, 2. A community member commented on these changesets and reverted them.

The community is great at responding to mapping issues but there are few issues lying under the rug. When we see unexplained edits without a clear comment or source, we do not go and fix them immediately, but let the user know the best practice and try and encourage them to to become a better mapper.

During the last 3 months the data team at Mapbox has commented on around 78 changesets and fixed only around 10 changesets. Over the course of last 1 year we have commented on around 250 changesets that did not get a reply from the user (quick map of these changesets).

It is a very subjective question to ask how long do we wait before we take the plunge into fixing or reverting changesets like these which may be suspicious, but is difficult to verify from the original mapper. Happy to hear how you approach this issue.

Presentando OpenStreetView

Posted by Mapanauta on 17 August 2016 in Spanish (Español)

Post Original: Martijn Van Exel

Traducción: Mapanauta

Después de casi un año de estar pensando, desarrollando y hacer pruebas ¡el equipo de OSM de Telenav está listo para presentar OpenStreetView a todos los mappers de OSM! OpenStreetview (OSV) es la plataforma libre y abierta de imágenes a nivel de calle diseñado 100% con OSM y teniendo en mente a los mappers.

Presentamos oficialmente OSV a la comunidad OSM en State of the Map US, donde tuvimos una charla de 20 minutos y un stand donde dimos cochecitos a control remoto para todos los que se habían registrado :). Los coches se acabaron rápidamente - ¡casi la mitad de las personas de SOTM US se habían registrado! -Pero todavía puedes ver la sesión gracias a los grandes organizadores de SOTM US que hicieron grabaciones de todas las sesiones profesionalmente. Si tienes 20 minutos y no te gusta leer, ver el video va a ser la mejor manera de entender qué es OSV y cómo se puede utilizar para mejorar OSM. O si vienes a SOTM en Bruselas, puedes conocer a nuestro equipo allí (¿más cochecitos a control remoto? ¡Quién sabe!) Y puedes asistir al workshop.


El stand de OpenStreetView en SOTM US_

SI prefieres leer ¡lee esto! Me gustaría introducir rápidamente OSV, qué componentes tiene y por qué creemos que es la opción #1 de imágenes a nivel de calle para OSM y por supuesto cómo contribuir y usarlo.

Componentes OpenStreetView

OSV es un sitio web,, son aplicaciones móviles libres y de código abierto código abierto para Android y iOS, es un editor especializado de mapas, es un plugin para JOSM, y por supuesto es un servidor back-end. También está planeado tener apoyo para iD.

El sitio web es donde vas a explorar imágenes de todo el mundo, ver tablas de liderazgo y tu propio perfil y trayectos. Para ver tus cosas personales, tendrás que iniciar sesión. Tu cuenta OpenStreetView está vinculada a tu cuenta de OSM, por lo que no es necesario crear una cuenta separada. Todo lo que guarda cuando ingresas por primera vez es todo lo que es público en OSM. (Si desea comprobar lo que es eso, ir a, cambiando 8909 con tu ID de OSM - a menos que quieras ver mis detalles).


Las aplicaciones se pueden descargar de forma gratuita desde la tienda play/app store. Para Android también puedes descargar el APK directamente. Son aplicaciones optimizadas para manejo pero también funcionan para andar en bicicleta y para ir caminando. Aparte de grabar trayectos, también puede subirlos OSV. Esto si lo deseas sucederá de forma automática cuando se introduce WiFi. Finalmente puedes revisar tus trayectos locales y de servidor y ver tu perfil. Incluso si no has iniciado sesión en el sitio web, puedes iniciar sesión en OSV con las aplicaciones, también a través de OSM OAuth. De cualquier manera, esto creará una cuenta para ti en OSV.


Una cosa que es muy específica para OSV es que se puedes vincular la aplicación a un dispositivo de seguridad OBD2 en tu vehículo. Esos son pequeños dispositivos que leen desde el puerto OBD2 de tu coche. Casi cada coche tiene uno. (Reto: ¡encontrar el tuyo!). El aparato lee todo tipo de información de diagnóstico del coche y lo transmiten a través de Bluetooth o WiFi. Cuestan alrededor de 20 euros. Una lista de los equipos compatibles con OSV está en el Wiki de OSM. (Ehm, es una lista muy pequeña hasta el momento. Si tienes un modelo diferente, por favor ¡agrega tu experiencia!)

obd2 dongle

OSV leerá la curva de velocidad para mejorar la precisión de la señal GPS que se registra para tu trayecto. Es extremadamente útil cuando la recepción GPS es pobre o se pierde por completo, por ejemplo, en una zona densa cubierta de árboles o en túneles. La navegación estimada es proporcionada por la unidad OBD2 y mantendrá la alineación adecuada a la carretera. Aquí verás lo que significa cuando circulas a través de un túnel (azul = solamente GPS , perdió la señal, rojo = con conexión OBD2).


Las aplicaciones OSV también tienen detección de señal incorporado. Así que esto no se hace en el servidor, pero a ¡60FPS en el cliente! Esto significa que detectará las señales de límite de velocidad, y más por venir, en tiempo real y puede advertirte cuando se conduce a alta velocidad. Esta función de advertencia está casi lista y estará en una de los próximas versiones. (Actualizamos las aplicaciones con mucha frecuencia.)


El plug-in JOSM se encuentra en una fase beta temprana. En este momento simplemente mostrará la ubicación de las imágenes en el servidor OSV, y puedes hacer clic sobre ellos para mostrar la imagen en el panel OSV. Es una funcionalidad básica, pero funciona :) y esperamos que tengas ideas (o incluso código) para mejorarlo.


Hablando de ideas, ya tenemos una comunidad activa reportando problemas y sugerencias en Github. Este es el mejor lugar para informarnos de cualquier bug e ideas que tenga sobre cualquier parte de OSV. Github es también el lugar donde se encuentra todo el código fuente de todos los componentes mencionados aquí. Casi todo en OSV es de código abierto y si aún no está ahí estamos viendo la forma de cómo hacerlo código abierto.

Si no te gusta Github o no quieres crear una cuenta allí, también puedes escribir a con tus ideas o informes de bugs. También estamos en Twitter como @openstreetview y estamos entrando a Facebook e Instagram si te gusta ese tipo de cosas.

Si checas Github, verás que también tenemos herramientas para cargas fotos existentes de tu Virb / GoPro y otras cámaras de acción. Estos son scripts en Python, pero también tenemos una herramienta de GUI en la que puedes arrastrar y soltar los directorios sobre los que deseas cargar. Esto está en fase temprana beta, pero si quieres una copia, me puedes contactar.


Hay dos componentes que no he mencionado todavía: el editor de mapas (Map Editor) y la parte del back end. Quiero dejar estos para un post aparte que voy a escribir pronto. Aquí hay una captura de pantalla del editor de mapas:


¿Por qué OpenStreetView?

Creemos que OpenStreetView es la opción # 1 para las imágenes a nivel de calle de OSM. No sólo porque es casi completamente de código abierto sino también porque permaneces con el control total de los datos subidos a la OSV. Siempre podrás borrar fotos individuales, viajes o incluso borrar todo y eliminar tu cuenta si en cualquier momento ya no deseas ser parte de OSV. Esta opción se encuentra en el sitio web, sin necesidad de enviar un correo electrónico a nadie ni presentar ninguna solicitud.

Otra razón es porque estamos construyendo una plataforma que está muy estrechamente integrada con OSM. Esto es obvio desde la manera en que manejamos las cuentas de usuario: iniciar sesión con OSM, no tienen que ser cuentas por separado. Pero también es más profunda por la integración con OSM es muy estrecha: mapeamos todos los trayectos a caminos de OSM, por lo que podemos vincular ida y vuelta entre viajes / imágenes y objetos de rutas OSM. Esto abre todo tipo de posibilidades interesantes, y me gustaría escribir también un post sobre esto más adelante.

Por ahora nos gustaría que le des una oportunidad a OpenStreetView. Descarga la aplicación en tu teléfono, inicia sesión y comenzar las capturas. Háblanos de tu experiencia. Explora lo que ya existe. Y lo más importante ¡por favor utilízalo para mejorar OSM!

Big personal milestone met today. Throughout my town, I have mapped all the roads through GPX tracks, and I removed all the TIGER:reviewed=no tags, in openstreetmap. Admittedly, I do live in a small town, but it is a good feeling to finally say that I have seen first-hand all of those little roads.

Where to go now? There is really so much left to do, with stop signs, buildings, street addresses, land types, and social structures. But, I am still excited to continue street mapping, so I will be pushing into the bordering towns and verifying the TIGER data there.

I am starting to find uses for more tools. I used OSMAnd+ to capture some pictures, for the first time. The JOSM integration for GPX images is really terrific. I have installed openstreetview, and I am looking forward to trying that on a future ride. There are still many tools left to explore, and I will continue to improve my street verification workflow.

Mapeo intangible, fotocaminata de la memoria

Posted by mapeadora on 16 August 2016 in Spanish (Español)

La movilidad es un tema amplio que no se limita a la movilidad cotidiana, aunque en estos términos lo estamos tratando más comunmente. En ocasiones Repubikla pone su pericia al servicio de proyectos que rebasan su objetivo central e interrogan las diferentes dimensiones del concepto de movilidad.

Alt textEn el pasado taller de mapeo de #Repubikla y #Mapeaton del mes de mayo en Morelia (organizado por Bicivilízate A.C.), Fabiola Rayas Chávez planteó su interés para una colaboración entre Repubikla y su proyecto artístico basado en el recuerdo de los desaparecidos en Michoacán.

Su proyecto, como parte de su investigación de maestría, es pluridimensional: fotográfico, cartográfico, performativo y editorial, se intitula El caminar y los mapas de la memoria. Se encuentra información con el hashtag #PerformanceDelCaminar. El arte es utilizado en este proyecto como medio de expresión política, visibilizando el contexto hacia públicos no sensibilizados con el contexto, rompiéndo con el silencio que acompaña las numerosas desapariciones en el estado en Michoacán.

"El tema general de esta investigación es la performance del caminar como herramienta de visibilidad del cuerpo desdibujado del desaparecido en Michoacán. Refiriéndonos a desdibujado como una acción impuesta por el entorno, el desaparecido no deja de existir, quedan sus pasos guardados en el espacio que recorría, y se dibuja esa persona desde la memoria de sus familiares. Aunque quieran borrarlos, quedan presentes en el recuerdo colectivo."

Fabiola realiza caminatas que replican los recorridos cotidianos de los desaparecidos, sola y acompañada de la comunidad y de los familiares de los desaparecidos. A través del ejercicio, se acerca a la situación familiar y a la vivencia de la desaparición por sus cercanos, pero también al impacto de la desaparición en la comunidad: aislamiento, fragmentación.

Alt text Alt text -Performance del Caminar Fabiola Rayas/ Alberta Corona. 2016. Registro Ceniza Pura-

La desaparición forzada, explica Fabiola, es implementada por el Estado mexicano o cómplices del Estado, desde los años 1970 actualmente sigue siendo utilizada como método de fragmentación de la comunidad y terror. Los primeros datos de desaparición en el estado son el caso de los cinco miembros de la familia Guzmán Cruz, quienes fueron secuestrados, torturados y desaparecidos (véase Abdallán Guzmán Cruz y Julio Pimentel, 2011, Los Mártires de la Democracia. La larga lucha de una familia de la Comunidad Indígena de Tarejero por la verdad y justicia, s.e.).

La frecuencia de estas atrocidades ha incrementado con la guerra contra el narcotráfico y la militarización del estado de Michoacán y siguen teniendo actualidad aunque se encuentran invizibilizadas y banalizadas, se recurre a la criminalización y al silencio colectivo como métodos de control, fragmentación y de miedo.

El arte es el medio por excelencia para resignificar y cuestionar lo invisible, en sus dimensiones política y culturales, renovando las plataformas de comunicación.

Alt text El proyecto Performance del Caminar se basa en distintas técnicas audiovisuales, entre cuales el mapa de los recorridos realizados en el Estado de Michoacán (Morelia y otras localidades) con varias familias, que se relaciona con fotografías georeferenciadas utilizando la aplicación abierta #Mapillary.

Alt text Alt text Alt text#Repubikla colabora con Performance del caminar con el interés de experimentar con nuevos métodos del mapeo con imágenes y ayudar este proceso narrativo plasmado en el espacio. Se inscribe en una línea donde el grupo de trabajo indaga de manera abierta las dimensiones sufridas de la movilidad, para grupos personas que experimentan barreras en su libre movimiento, que afecta potencialmente y efectivamente su integridad por una gran diversidad de situaciones.

Introducing OpenStreetView

Posted by mvexel on 15 August 2016 in English (English)

After almost a year of thinking, development and testing, the OSM team at Telenav is ready to present OpenStreetView to all OSM mappers! OpenStreetview (OSV) is the free and open street level imagery platform designed 100% with OSM and mappers in mind.

We officially presented OSV to the OSM community at State of the Map US where we had a 20 minute talk and a booth where we gave away crazy little remote controlled cars to everyone who signed up :). The cars were gone quickly – almost half of the people at SOTM US signed up! - but you can still see the talk thanks to the great SOTM US organizers who had all the sessions professionally recorded. If you have 20 minutes and don't like reading, watching that video is going to be the best way to be introduced to what OSV is and how you can use it to improve OSM. Or if you are coming to SOTM in Brussels, you can come meet our team there (more remote controlled cars? Who knows!) and attend the workshop.


The OpenStreetView booth at SOTM US

If you do prefer reading, read on! I wanted to quickly introduce OSV, what the components are, why we believe it is the #1 choice of street level imagery for OSM, and of course how to contribute and use it.

OpenStreetView components

OSV is a web site,, free and open source mobile apps for Android and iOS, a specialized Map Editor, a plugin for JOSM, and of course a back end server. Support for iD is also planned.

The web site is where you go to explore imagery from all over the world, see leaderboards and your own profile and trips. To see your personal stuff, of course you will need to sign in. Your OpenStreetView account is linked to your OSM account, so you don't need to create a separate account. All we store when you sign in for the first time is whatever is public on OSM. (If you want to check what that is, go to, changing 8909 to whatever your OSM ID is -- unless you want to see my details.)


The apps are free to download from the play / app store. For Android, you can also download the APK directly. With the apps you can capture trips. They are optimized for driving but also work well for biking and walking scenarios. Apart from recording trips, you can also upload your trips to OSV. This will happen automatically when you enter WiFi, if you want. Finally you can review your local and server trips and see your profile. Even if you have not logged in on the web site, you can log in to OSV with the apps, also through OSM OAuth. Either way, this will create an account for you on OSV.


One thing that is really specific to OSV is that you can link the app to an OBD2 dongle in your car. Those are little devices that read from the OBD2 port in your car. Almost every car has one. (Challenge: find yours!). The dongle reads all kinds of diagnostic info from the car and broadcast it over Bluetooth or WiFi. They cost around 20 Euros. A list of OSV compatible ones is on the OSM wiki. (Ehm, a very small list so far. If you have a different model, please add your experience!)

obd2 dongle

OSV will read the speed and curve to improve the accuracy of the GPS signal that is recorded for your trip. It comes in extrememly handy when GPS reception is poor or lost altogether, for example in dense tree cover or in tunnels. The dead reckoning provided by the OBD2 unit will maintain proper alignment to the road. Here you see what that means when you are driving through a tunnel (blue = GPS only, signal lost, red = with OBD2 connection).


The OSV apps also have sign detection built in. So this is not done on the server but at 60FPS on the client! This means that it will detect speed limit signs, and more to come, in real time and can warn you if you are speeding. This warning feature is almost ready and will be in one of the next builds. (We update the apps very frequently.)


The JOSM plugin is in an early beta stage. Right now it will simply display the locations of images on the OSV server, and you can click on them to show the image in the OSV panel. Basic functionality, but it works :) and we hope that you have ideas (or even code) to improve it.


Speaking of ideas, we already have an active community reporting issues and suggestions on Github. This is the best place to let us know of any bugs and ideas you have about any part of OSV. Github is also where all the source code for all the components mentioned here is located. Almost everything in OSV is open source, and if it is not we are looking at how we can make it open source.

If you do not like Github or do not want to create an account there, you can also write to with your ideas or bug reports. We are also on Twitter as @openstreetview and we are getting on Facebook and Instagram if you're into that kind of thing.

If you check Github, you will see that we also have upload tools for your existing Virb / GoPro and other action camera images. These are Python scripts, but we also have a GUI tool that you can just drag and drop directories onto to upload. This is in early beta but if you want a copy, let me know.


There are two components that I have not mentioned yet: the Map Editor and the back end. I want to save those for a separate post that I will write soon. Here is a screenshot of the map editor:


Why OpenStreetView?

We think that OpenStreetView is the #1 choice for street level imagery for OSM. Not only because it is almost completely open source. You also remain in full control of the data you upload to OSV. You can always delete individual photos, trips or even delete everything and remove your account if at any moment you don't want to be a part of OSV any longer. This option is on the web site, no need to email anyone or submit a request.

Another reason is because we are building a platform that is very tightly integrated with OSM. This is obvious from the way we handle user accounts: log in with OSM, no separate account. But also deeper down the integration with OSM is tight: we map all trips to OSM ways, so we can link back and forth between trips / images and OSM way objects. This opens up all kinds of interesting possibilities, and I want to spend a separate post on that as well.

For now, it would be cool if you would give OpenStreetView a try. Download the app for your phone, sign in and start capturing. Tell us about your experiences. Explore what is already there. And most important please use it to improve OSM!

Note that OpenStreetView is not a project run by OpenStreetMap or the OpenStreetMap Foundation. It is maintained by Telenav, where I work, for the sole benefit of improving OpenStreetMap.

My Trip to Public Works

Posted by mtc on 15 August 2016 in English (English)

Accessing forested trails is a particular interest of mine. Learning about a new accessable trail encourages my participation in OSM. Discovering a couple "secret trails," by studying and updating maps, has given me new - and especially enjoyable - local recreation areas. In order to record more GPX tracks in wooded areas, I need some verification that the lands are publicly accessable.

The city government holds many information records about the land, and I asked their advice today. As I expected, several of the first people that I met did not fully understand my interest in exploring wooded areas, but they kept directing me toward more knowledgable people: from City Hall, to Public Works, to Engineering, to the GIS Coordinator.

Finally, in the small office of another map enthusiast, the city maps of land ownership were examined, including a two hundred page online PDF of land lots made public after being abandoned by their owners. I would never had thought to look there.

This information will keep me very much engaged with mapping the woods in my area. I recommend asking for help to all other OSM mappers. I found people in these city offices understanding of a desire to explore natural areas, and I never found myself defending my interest in learning about public spaces.

I appreciate the patience everyone gave me. Great seeing an actual office where GIS is used in city planning.

Some Important Questions for OSM Trainer

Posted by Sawan Shariar on 14 August 2016 in English (English)

If you are a Trainer of OSM Platform you have to face some common but very important questions. I want to try to find out this kinds of questions and give its suitable answer.

****01. What is Map?

-----> Answer: A map is a symbolic depiction highlighting relationships between elements of some space, such as objects, regions, and themes.

****02. What is OpenStreetMap?

-----> Answer: OpenStreetMap is a free, editable map of the whole world that is being built by volunteers largely from scratch and released with an open-content license. OpenStreetMap is, as the name suggests, an open source map of the world ( It has been built up in a concept similar to Wikipedia. It is called the free wiki world map, a collaborative project to create a free editable map of the world. A digital map is always handy for various purposes. It can be used in navigation, in research, in development of location based applications. When the map is free, its usability is guaranteed for everyone. And as OpenStreetMap is open source, its development is rapid and dynamic.

****03. Why OpenStreetMap?

----> Answer: OpenStreetMap is a free, editable map of the whole world that is being built by volunteers largely from scratch and released with an open-content license.

****04. Why don't you just use Google Maps/whoever for your data?

----> Answer: Because that data is copyrighted and owned by multiple organisations like the Ordnance Survey. Google/whoever just licenses it. If we were to use it, we'd have to pay for it.

****05. Who owns OpenStreetMap?

----> Answer: You do. The data and software is owned by you, the contributors. There is an organisation called the OpenStreetMap Foundation which exists to protect, promote, and support the project, but does not own the data.

****06. Why would you use OpenStreetMap if there is Google Maps?

----> Answer: There is no ultimate answer as to which one is better. These two have as many similarities as differences. They are based on different fundamentals, but they solve the same basic human need to know “WHERE”. The key difference between these two mapping environments is a philosophic “Open” vs. “Closed” approach with how the data is collected and distributed. The main difference between these two services is that every edit you make to OSM is owned by you and the community, while every change you make to Google Maps… will be owned by Google. The OSM community is what makes the project so special. Thousands of volunteers from all around the globe are updating the map as their world changes around them. Every update is immediately visible to all other users and is version controlled. There are no corporate map cycle releases, approvals and KPIs that are typical to large organizations. This community is also what ensures the high quality and granularity of OSM maps. Although Google spends quite a lot of time and resources on keeping maps up-to-date, its data quality is not necessarily better than OSM. In many, especially less developed areas, the OSM community has managed to gain even higher data granularity than any other map source. Commercial map data suppliers usually focus on updating map features which are most profitable to sell. Since the OSM community does not have to worry about selling maps, it allows the community to be creative and make maps focused on hikers, cyclists, physically challenged, sailors and practically any interest group. You can map crops, the number of windows on Empire State Building or even the age of a particular tree. Even when it comes to routing and navigation, OSM doesn’t stay behind. Telenav has started using OpenStreetMap data in their Skobbler navigation app.

****07. Advantages of OpenStreetMap

----> Answer: Free:- UOpenStreetMap® is open data, licensed under the Open Data Commons Open Database License (ODbL) by the OpenStreetMap Foundation (OSMF). You are free to copy, distribute, transmit and adapt our data, as long as you credit OpenStreetMap and its contributors. If you alter or build upon our data, you may distribute the result only under the same licence. The full legal code explains your rights and responsibilities. The cartography in our map tiles, and our documentation, are licensed under the Creative Commons Attribution-ShareAlike 2.0 license (CC BY-SA). Full:- Actually no mapping service has 100% of the planet’s geographic information. However, OSM is constantly updated through collaboration of companies, government institutions and the wider community that often send information of new locations or corrections of the existing ones. This allows the service to have more precise information of places that are poorly known. Unlike Google Maps that focuses on detailing the information of the major cities. Without restrictions:- In services like Google Maps you must pay to use the service when the access traffic is high, while in OSM access is provided free and without any restrictions. Standard: OSM uses the standard EPSG: 4326, one of the most currently used in cartography. Customizable:- OSM is a service, and as such, it may be used by third party applications for customization. Currently there are APIs like Openlayers (Implemented in JavaScript) that allows you to create web applications using the OSM service, providing a rich set of functionality (set markers on the map, labels, overlapping layers, widgets, popups, among many other elements that can be seen on the website of examples). Fast:- Even sometimes it gives the impression that its loading is faster than Google Maps. Stable: Backed by the University College London (UCL) and Imperial College London (ILC) where the main servers stay. They also have distributed servers around the world to meet demand of users in a reliable and robust way. Effective:- The group of developers are constantly working on adding new features to the service.

****08. Disadvantages of OpenStreetMap

----> Answer: Documentation:- The official documentation is not complete and not very clear. Many times we must search in forums and blogs to understand some functionality. Incompatibility:- Some users have reported OSM erroneous behavior when it is used in conjunction with other tools. For example: Maps are displayed distorted when OSM is used with Twitter Bootstrap. However, this bug is easy to fix (we will share the solution in another article later).

I’m not saying that OpenStreetMap is perfect. No map is. But when you consider all pros and cons, maybe Google Maps is not the best solution for all use cases. There are many applications where the map should be treated as an important public good, rather than a commodity controlled by large organizations. At the end, why would you rely on a global corporation to tell you what is the name of a street in your own neighborhood? So don’t be afraid and try it out here
