સ્વામી વિવેકાનંદ સર્કલ, મક્કાઇપુલ, નાનપુરા, સુરત.
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.
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.
En 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.
-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.
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.
#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.
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.
OSV is a web site, openstreetview.org, 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
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!)
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 email@example.com 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:
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.
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.
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 (www.openstreetmap.org). 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
****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 http://learnosm.org/en
Today, I searched for a school in OSMAnd+, with a POI search. I was surprised to see so few in the area, so I jumped onto JOSM to investigate.
I saw some schools with building=school tags, while other schools had amenity=school tags. What is going on here? On to the OSM Wiki to learn more. Ah, ha! The schools are supposed to have a border defined which uses the amenity=school tag, for the perimeter of the school grounds. The amenity tag, not the building tag, should carry the name of the school complex. I assume the building's name= tag is used to define the name of the building, instead. Clever.
There are some non-obvious ways of doing things in OSM, but the more that I learn, the more other OSM methods become more intuitive. Are there other boundaries that are better defined by the amenity= tag?
Today, Ruth and I attended the birthday party for OSM at Greeley Park in Nashua, New Hampshire USA.
It's always nice to see old friends and to attach names and faces to folks you recognize from diary entries, mailing lists and changeset comments.
It's amazing how fast a conversation can start when someone says "How do you.....?
Several of the attendees were
A 13 year old girl who's made a website for the trails in her town using a tailored cartographic style.
One of the "fathers" of the great MA imports.
A prolific area mapper who has moved to Portland OR
I'll be checking the OSM Birthday wiki next year to see where the party will be.
Many thanks to rozzin for organizing this event.
The key highway=* is the main key used for identifying any kind of road, street or path. The value of the key helps indicate the importance of the highway within the road network as a whole. See the table below for an ordered list from most important (motorway) to least important (service).
"Highway tagging samples"
Roads: motorway, trunk, primary, secondary, tertiary, unclassified, residential, service
Link Roads: motorway_link, trunk_link, primary_link, secondary_link, motorway_junction
Special: living street, pedestrian, bicycle road, track, bus guideway, raceway, road, construction, escape
Paths: footway, cycleway, path, bridleway, steps, escalator
Sidewalks : sidewalk, cycleway lane, cycleway tracks, bus and cyclists, lanes:psv, busway
Lanes: number of lanes, direction instructions ("turn lanes"), signposts
In 14 May 2015 i joined the #OpenStreetMap team as a mapper . That time i feel so much bad & think why i do this ? But after a long time with osm i learn lot of thinks. Now i am a osm map trainer . That's why i know some common question's answers . Now i share it for new comer who recently joined or want to be joined it .
- Why Map ?
=> When you trace roads, buildings and houses on a Map that will aid in humanitarian missions. So..
- What Can I Do ?
=> Join the community of online volunteer mappers. Make a powerful contribution with an Internet connection and basic computer skills, even if you do not live in the area you are mapping. Use satellite imagery to trace the outlines of roads, structures and land features for the creation of openly available data used to produce maps that help the humanitarian and development community.There are several ways to get involved and aid humanitarian crowd-sourced mapping initiatives. This site provides one such path.
- Why OpenStreetMap ?
=> Through the Open Data Commons Open Database License 1.0 OpenStreetMap (OSM) contributors own, modify and share data publicly. There are many other free maps on the Internet, but most have legal or technical restrictions preventing others from using the data openly. With OSM both the maps and underlying data can be downloaded for free, for developers or anyone to use or redistribute. Additionally, in many places of the world where there is no commercial motivation to develop this data, OSM is often the best available resource.
so don't think why and how, #just contribute data on it and help the world.
Thanks OSM for making this wonderful opportunity for us . Also thanks to BDRCS and Brother Ahasanul Hoque
12th August, 2016 - a day of my lifetime achievement. Ahasan vai just started talking about the techniques of playing games with maps and I was like a baby seeing its desired toy. From yesterday morning to today's evening, it gave me a world full of enthusiasm, love for work and a toy for playing with the world. Love this mapping, proud to be a mapper and wish to make a bunch of mapper too. Hope for the best. We shall overcome.
Two days long OpenStreetMap training (Data For Action Project) at IDMVS , University of Dhaka; Arranged by Dhaka City Red Crescent Unit, (BDRCS) and OSMBD, Dhaka on August 12-13, 2016.OpenStreetMap training

No, I dod not cancel, “OSM go”, I extended the idea. But first, thank you for the Aber erst mal Danke für die suggestion. At first, the reactions was limited, after a week it got nice.
After I postet that PSM-go, I spend a day to take snippets of old code of mine. And at night, I had that first 3D-View. It enthused me so much, to have a sleepless night, my imagination running wild: Walk through OSM in 3D (not that discouraging Pokemon style, something tidy), overlay data, not only walk but “fly”; thats why I used the term OSM-Earth. Sure, more layers with external- / realtime data are possible. May be switching to 2D mode.
- A running gamification (in 2D): http://www.kort.ch
- A 3D-Renderer (java,static): osm2world.org
- Ingress, the “precursor von PG" OSM based: github.com/egore/osmgress
- Other tools to motivate editing: Mapillary, OSMand and Maps.ME.
With edits there are a lot of doubts because newbies shall do it. I like the idea, this edits to go into a pool, used by “real” OSMer, loaded in an editor and verified.
What next? Just things I will have fun with :-)
- First get JSON data around the actual position by Overpass. So “real” things will be visible, not dummy nodes etc. That will motivate to show more and more details in 3D.
- The handling of moves are improvable for sure. A Cardboard mode will come. Gi by keyboard&mouse, touch gestures or VR gadgets to any place and view angle on Earth.
- And the first “gaming”; just real (GPS) walks will give first point. By personal experience, I think, gather house numbers will be a niche first useful action.
Below a view of my first rendering, an OSM-like style. At the German post, I will append an style, as close as possible to the Pokemon map style. And if you like to test it yourself (without guarantee): www.ac1000.de/osm/go or as OSM-style: www.ac1000.de/osm/go?x It works with keyboard, mouse, touch and device turning, but still petting.
(Do I really need to translate my German posts? Anyone interested? Is there a way to only offer automated translation, I would prefer to code)
Nein, “OSM go” habe ich nicht gecancelt sondern die Idee erweitert. Aber erst mal Danke für die Anregungen. Die Reaktionen waren zunächst mäßig, nach einer Woche dann schon schön.
Nach meinem Go-Post habe ich einenTag lang einige Teile aus alten Code von mir zusammengeglaubt und hatte abends schon eine erste 3D-Ansicht. Was mich so begeistert hat, das mir einer schlaflosen Nacht die Phantasie durchgegangen ist: In 3D OSM durchwandern (nicht der abschreckende Pokemon-Style, was gescheites), Daten einblenden, nicht nur Laufen, auch “fliegen”; daher jetzt der Begriff “OSM Earth”. Klar sind dann weitere “Layer” auch mit Echtzeitdaten möglich. Vielleicht auch ein Wechseln zur 2D-Ansicht.
- Eine laufende Gamification (in 2D): http://www.kort.ch
- Ein 3D-Renderer (java,statisch): osm2world.org
- Ingress, der “Vorgänger von PG" auf OSM Basis: github.com/egore/osmgress
- Andere Tools, die zum Editieren Motivieren: Mapillary, OSMand and Maps.ME.
Bei Edits gibt es viele Bedenken, da es ja Neulinge sein sollen. Mir gefällt die Idee, das diese Edits in einem Pool landen, die dann “echte” OSMler in ihren Editor laden und prüfen.
Wie geht es weiter? Immer das, was gerade Spaß macht :-)
- Als nächstes gedenke ich von Overpass JSON-Daten der eigenen Position zu holen. Dann werden “echte” Sachen dargestellt, statt Test-Nodes Etc. Das wird motivieren, immer mehr Details auch in 3D darzustellen.
- Die Bewegungsmöglichkeiten sind verbesserungswürdig. Ein Cardboard-Mode kommt dazu. Mit Tastatur&Maus, Touch-Gesten oder VR-Gadgets “Bewegen” zu jedem Blickpunkt der Erde.
- Und erstes “Spielen”; schon echtes (GPS) ‘rumlaufen gibt erste Punkte. Aus persönlichem Erleben halte ich das Erfassen von Hausnummern für eine gute erste nützliche Aktion.
Hier ein Bild meines erstes Renderns, möglichst nahe am Pokemon-Kartenstiel. Einen OSM-Like-Stiel hänge ich an den englischen Post. Und wer es selbst ausprobieren möchte (ohne Gewähr): www.ac1000.de/osm/go oder als OSM-Stiel: www.ac1000.de/osm/go?x Die Bedinung geht mit Tasten, Maus, Touch und Drehen, ist aber noch recht fummelig.
