public_transport tags don't add any information

Posted by Polyglot on 19 July 2018 in English (English)

In 2012, the 'new' public_transport scheme was voted. What seemed like a good idea at first, has not led to unification though. I was not smart enough at the time to see how this would develop, but today with the benefit of 20/20 hindsight it it's apparent that we are on the wrong track.

The way the wiki formulates it at present, even though I have tried over the years to keep it in check, we should supposedly map 2 objects for each and every stop and then add both of these to the route relations.

I'm sorry, but that is unacceptable! For one thing, I need a SINGLE object, preferably a node where all the details of the stop go. That has always been the way we do things in OpenStreetMap. The node that gets the stop_position tag is NOT suitable for that purpose, as it is not immediately apparent on what side of the street the stop is.

So, over the years I have tried to work with public_transport=platform and stop_position tags on the stop nodes I've been mapping. The idea was that, in time, highway=bus_stop would be replaced by those tags. Only that is not possible, for one thing, those nodes we're mapping to represent the stops, were not supposed to have a mode of transport on them. So it is utterly impossible to drop highway=bus_stop from those nodes.

OK, let's step back for a moment: highway=bus_stop is here to stay, wait for it... it's coming... the conclusion: public_transport=platform tags are NOT ADDING any information. highway=bus_stop says it all. Sorry that it took me a few years to figure that out!

Of course, now the epiphany dawned on me, I decided to revisit all 70000 bus stops around Belgium. So since yesterday I started to remove public_transport=platform/bus=yes tags from all those stops, in packages of about 100-150. Obviously that's not all I'm doing, some stops have moved, we have better imagery now than we did 5 years ago, there is a new bus_bay tag since last summer. It will take 6 to 12 months to complete this mission, but soon those tags that don't add actual information will disappear from sight.

It's time we came up with a scheme to map public transport that is: * easy to work with * easy to maintain * easy to visualise and that: * does not duplicate information * does not force mappers to add 2 objects to route relations

I have a clear vision of how we can accomplish that.

India is not Bharat

Posted by mdmahir on 19 July 2018 in English (English)

இந்தியா என்பது ஹிந்தியா அல்ல. பாரத் என்று இந்தியாவை குறிப்பது தவறு. இந்தி தேசிய மொழி அலல. India என்றிருப்பதே சரி.

India is not Hindia. Please remove the word "Bharat" (1000km) in hindi from osm. Indians speak 100's of languages. Hindi is not a national language.

osmconvert

Posted by RichardKYZC on 19 July 2018 in French (Français)

Hi,

I realized a test with osmconvert. osmconvert file_original.pbf -o=file_o5m.o5m osmconvert file_o5m.o5m -o=file_final.pbf

There is a difference of size between file_original.pbf and file_final.pbf The file_final.pbf is smaller.

Can you explain the difference between the two files ? Does it exist a difference of quality, precision for the map defined by the file_final.pbf ?

In final, the osmconvert will be use to append data in a database with the option --subtract.

Thanks Best regards Richard

areál Žilinskej univerzity v Žiline - UNIZA

Posted by marton_tud on 19 July 2018 in Slovak (Slovenčina)

chcel by som upraviť objekty v areáli UNIZA - začal som v júli aktualizovať názvy budov, parkoviská, niektoré prístupy do budov, atď. napr. s pomenovaním budov budem asi experimentovať a neskôr sa rozhodnem pre konečné riešenie - nepáči sa mi názov "Fakulta prevádzky a ekonomiky dopravy a spojov - Budovy BF a BG", síce som ho nastavil sám, ale skúsim to nahradiť používaním building:part (uvidím, ako to bude vykresľovať názvy RA a RB v prípade budov Fakulty riadenia a informatiky)

hľadal som nejaké vzory z zahraničí - napadlo ma kuknúť sa do Švajčiarska. čo som našiel ma prekvapilo. na University of Zurich používajú napr. “addr:housename=UZH-Y55” pre označenie "University of Zurich", budova Y55. úplne som prekvapený, ako je zmapovaný campus Technickej univerzity v Lausanne. sú tam použité multipolygóny...

JOSM Reset unter OSX

Posted by address history org on 19 July 2018 in German (Deutsch)

Wiederholt bin ich mit dem Problem konfrontiert, dass der Editor JOSM auf meinem MacBookPro, entweder mit der Zeit sehr langsam wird, oder sonst ungewöhnlich reagiert. Manchmal kommt es vor, dass plötzlich beim setzen eines Nodes, sich der Kartenausschnitt ruckartig seitlich verschiebt.

Nach einigem Probieren wende ich nun bei solchen und ähnlichen Problemen folgende JOSM Reset Vorgangsweise an.

Anschließend die gewünschten JOSM Einstellungen wiederherstellen. Nun von diesen Einstellungen eine Sicherungskopie anlegen. Dazu "Ausgewählte Elemente exportieren" anwenden.

Kommt es erneut zu Problemen, so kann ich nach erfolgten erneuten Reset, durch Einspielen des Backups, meine gewohnten JOSM Grundeinstellungen wiederherstellen, und so zügig weiterarbeiten.

Map-[A]ddiction has Rewards

Posted by tshedy on 16 July 2018 in English (English)

I have been OSM mapper since February 2015 and got enthusiastic about the change I was making in #MapLesotho. Being the spatial planner I realised the importance of OpenstreetMap data and how it would be useful in my job.

Being number one mapper in Lesotho opened doors for me, and in September 2016 I won a scholarship to study in Ireland doing MSc in Spatial Planning at Dublin Institute of Technology. I adapted easily in Ireland & met Ireland OSM community and also continued training school kids to map, and also how to use different Phone Apps such as mapillary, OSM Tracker, street complete and maps.me.

I wanted to be able to map more than what #MapLesotho taught me, so simaltaneous to moving to Ireland for town planning scholarship and internship I started mapping Ireland. I adapted to different ways of mapping and started mapping things in Ireland that aren't there in Lesotho such as the coast and heritage sites, different tags for different road uses, such as bicycle lanes, bus lanes, footpath etc. It was also fascinating to map high buildings because they are frequent in Ireland using maps.me and the sudden change when editing height of the buildings using the app was entertaining as well. Streetcomplete is another app that always got me curious because the more I used it the more I got different kinds of stuff to edit which I would say widened my experience with Tags also.

Being in a new country of course I wanted to get out and about, so I turned my curiosity into mapillary trips in all 32 counties and I became number 2 mapillary contributor in Ireland. The truth about me is when I do mapping stuff I make sure I do it well and conquer, hahah😊.

In June I became mapper of the month and that took me by surprise when I was contacted by a person I have never talked to before Marc Gemis because I never thought there are people out there who notice the effort and the changes I was making.

I know a lot of countries and places I have never been through mapping and I never want to stop. Anyday without mapping is a bad day for me. The mappers in the places I have lived know I show up and do my part and help others. I don't disguise that I am also happy to map on my own and I like to help new mappers all the time. Vote for me if you are like me, or want there to be more of me. If I win this I will show it to others to inspire them to start mapping.

Dados OSM em gps automotivo

Posted by Tomio on 16 July 2018 in Brazilian Portuguese (Português do Brasil)

Utilizar os dados do Openstreetmap em equipamentos de gps é algo que sempre procuro implantar.
Assim, meu gps automotivo Garmin utiliza mapas com dados OSM, elaborados pelo projeto CocarDL: http://cocardl.com.br/

Tenho trabalhado em outras utilizações com dados do OSM, como alertas de lombadas.

Recentemente elaborei alertas de pedágio das rodovias brasileiras, contendo os valores cobrados.
Esses alertas foram feitos em caráter experimental, através de exportações do overpass.
Os dados obtidos foram colocados em uma tabela csv e posteriormente gerados os alertas com o programa Poi Loader (da Garmin).

Exemplos do resultado:

Garmin Nuvi 2580tv:

Garmin Drive 50:

Estas utilizações tem inspiração no primoroso trabalho que o mapeador Fidélis Assis vem desenvolvendo com dados do OSM.
Além de mapas para o gps 7ways com dados do OSM, tem gerado também alertas.
Estes alertas podem ser convertidos para o gps iGO, com um conversor desenvolvido por ele: 7ways>iGO.

Faço esta postagem com intuito de incentivar outras idéias ou aplicações do OSM, no universo do gps, tipo: um alerta de pedágio com valores, para o Osmand?

Making Detroit the Best Bike Share Map in the World

Posted by mikelmaron on 16 July 2018 in English (English)

I took a tip from Dexter from the City of Detroit Office of Innovation, and started on the Detroit Mapping Challenge by browsing City of Detroit Open Data. What open data could help make OpenStreetMap Detroit the best map in the world? BikeShare locations looked like a useful and straightforward starting point. And now OSM Detroit has very accurate MoGo bike share docking stations. There turned out to be a few surprises getting there, and lessons to absorb for mapping all of Detroit.

The data looked decent on quick inspection, and is licensed public domain. Maybe a very small human supervised import is in order. I browsed OSM to see what was already there, and turned out this already all 43 docking stations were already added by mapper175, with the changeset comment Added nodes for MoGo Bike Share system stations (resurvey needed for most of them). Are they in the right place? Is there something a remote mapper could do here?

I picked the Second Ave & Prentis St docking station at random, and opened it up in iD.

I cycled through all the imagery options available to OpenStreetMap, and no evidence of a bike share dock station. Turns out MoGo launched just over a year ago and all of the aerial imagery is apparently older than that.

I then tried street level imagery. Bing Streetside is comprehensive but collected back in 2014. Fortunately in Detroit, Mapillary and OpenStreetCam have extensive and recent coverage. Clicking through the street level images in iD to find something with the correct alignment to capture the dock was sometimes tricky — depended on the precision of the capture position, the direction, the field of view, and distance. Confirming features seen in the street level imagery against aerial imagery was helpful to choose a well located shot.

For Second Ave and Prentis Street, the docking station moved just a few meters, from on street to inside a parking lot. While the accuracy of the first location in OSM was probably ok enough to find the docking station, the position of on the street vs sidewalk has substantial meaning for high definition mapping and analysis.

I next checked out the dock at Cass Ave & W Hancock St. The original position on West Hancock looked ok, but the OpenStreetCam imagery quickly confused me. One image showed the doc on West Hancock, and another from a few months later on Cass Avenue. I couldn’t trust what my eyes told me here — is the location or direction of the images incorrect? Am I looking at the same dock?

I searched and found that this dock had moved due to street construction. The reported move date didn’t quite match up with the first image but seemed reasonable to explain what I was seeing. And it also mentions the move of ****2nd Ave. and Prentis — somehow luckily the first two stations I picked had substantial changes.

The MoGo site also had a map, and browsing it, the locations for the above two dock stations were very accurate. It looked like the location in the MoGo map corresponded exactly with the docking station kiosk unit. Perhaps I could simply use these locations to correct the data in OSM. But what about the license? Asked Dexter and ..

.. he confirmed that I could us it in OSM and that they would now update the data set on the main Open Data site. Open Data is more than a data source, it’s a conversation.

But first, had to screen scrape. Viewing source, the dock locations were stored in two lists of coordinates. I wrote a quick script to scrape this and transform into GeoJSON and then load into iD as a local file.

I had confidence in this data from the first two stations, but decided to confirm each location from street level imagery before adjusting. I zoomed in on each station from the local file in turn, enabled street level imagery, clicked to find the best view and recency of imagery, until I had a confirmation of the MoGo location.

It became a bit monotonous, though still interesting to investigate the streetscape across Detroit. I began day dreaming about a process that would make it easier for me to confirm. Something that would show the current and new point, automatically determine the best source of imagery from all available — biased towards most recent, and including machine learning to filter images that probably have a dock in view. Step through each point, reposition if needed, and confirm.

For the most part, the locations were spot on. This one confirmed with Mapillary imagery contributed by, in fact, Dexter!

And in just a couple cases, very close but slightly off. Like the station above, where the MoGo map has the station on the street side of the sidewalk, but OpenStreetCam had the station closer to the building. I decided to go as close as I could tell from the imagery.

I learned a lot from the short exercise.

  • OSM is iterative. The first version of this data was pretty good, now it’s great. And we’ll need to update again as MoGo changes and grows.
  • Open data is a conversation, not just a download site. Connect with data holders and it will help unlock more data and possibilities.
  • Street level imagery is a superb source. Utilize as many sources as possible, research from multiple angles, and pay close attention to recency.
  • Human review is always key, but we need to make it very easy with processes that minimize drudgery and take best advantage of human intellect.
  • You can learn a lot about a city, even from far away. Takes patience but it’s rewarding to understanding the geography of a city.

There’s going to be a lot to learn about the city, and especially about the process of mapping, from making Detroit the best map in the world. Excited to see what happens next.

Another Neighborhood of Ashgabat Demolished

Posted by apm-wa on 15 July 2018 in English (English)

Yesterday I had too many other obligations to travel far, so I took about three hours of Saturday afternoon to cruise parts of Ashgabat I'd not visited for a while and to collect Mapillary imagery where there were gaps (uploads currently underway). The dacha community north of the Karakum Canal on the far east end of the city is gone. It was apparently demolished in the past months and has been bulldozed. I had no idea, but will have to revise the map. The road into the community has been blocked with a dirt pile. This is why ground truth is so important.

I have completed corrections to the A-381, P-1, P-15, P-16, and P-18 national highway routes in Turkmenistan. I have consulted with local sources to nail down exactly which roads are part of each route and think these five are now pretty accurate.

Торговые центры на карте

Posted by CupIvan on 14 July 2018 in Russian (Русский)

Продолжаю экспериментировать со своим минидвижком OSM. На сей раз попробовал вытащить на карту торговые центры и прикрутить минимальный валидатор, можно теперь их размечать в едином формате. А также проверить может это и не mall вовсе, а department_store

Ссылка на просмотр: http://osm.cupivan.ru/mall/#478/?z=13&lat=56.1432543123371&lon=40.392780303955085

В планах сделать ещё несколько парсеров сетевых POI (например Пятёрочки или Лукойла), положить их код и результат деятельности в удобном JSON на гитхаб. А потом как-то всё сопоставлять с OSM... JSON может ещё кому-нибудь понадобился бы, благо с гитхаба легко подключать его будет.

Также в чатике кто-то спрашивал про реки, прикольно было бы сделать, чтобы при нажатии на реку писалось куда впадает и так можно по цепочке дойти до морей. Либо какой-нибудь текстовый валидатор, раньше вроде был, а сейчас что-то не работает :-(

Does anyone else love this moment?
