Salmonberry River and Port of Tillamook Bay Railroad

il y a 3 heures 21 min

In August 2016 I was in the Portland, Oregon area for business reasons. I was however able to squeeze in some hiking time to enjoy the nice scenery that Oregon has to offer.

Among others, I found a hike along an abandoned stretch of the Port of Tillamook Bay Railroad online. The description sounded like a post-apocalyptic thing, so I was too curious to not do it. It was a great experience, and gave a good feeling of the forces at play to cause the destructions as seen there, which were 3 storms and the resulting water levels in the Salmonberry River.

However, when I later browsed the area on OSM I noticed that the Salmonberry River is not on the map at all. That could should not be the case, so I saw an oportunity to make my first big contribution to OSM.

Therefore I retraced my steps and combined it with info from USGS Topo maps to fill in the blanks and map the full river. Next to that I noticed that the Port of Tillamook Bay Railroad as imported from TIGER data, was not really accurate in position and none of the bridges and tunnels were put in. So I had work to do.

Five mugs of tea, one coffee, a skipped lunch, an emptied bag of Trail Mix and 13 edits later the whole river is mapped, the POTB railroad position has been corrected between Nahalem River and Wolf Creek Trestle, a few bridges have been put in and the Nehalem River has been slightly adapted. A bit more work to do, but I keep that for later! - A bunch of side branches that drain into the Salmonberry River - The tunnels of Port of Tillamook Bay Railroad - The Port of Tillamook Bay Railroad bridges east of Enright

I learned a lot about mapping and tagging today. I hope that will aid my future mappings and result in a short cycle time :).

How can we tag worker-owned shops or cooperatives?

dim 19 fév 2017 - 15:48

Case in point:

It's a bakery set up by anarchists and it is self-managed. There are also examples of self-managed coops, for which I can't find documentation on the wiki. It's also worth debating whether it would be useful to differentiate between coops and more generally worked-owned establishments.

What are you views on it?

What shall we have for diner tonight?

What shall we have for diner tonight? Improving the OSM map - why don’t we (14)

Some thoughts on restaurant and food-tagging on OSM.

A restaurant is considered an amenity and tagged with amenity=restaurant.
One would expect that in order to show what type of restaurant this is, or what food you can eat there, the next step would be:
After all, this is accepted:
But, alas, OSM is differently and so a new tagging was introduced to indicate what we can eat in a restaurant. No, they didn’t choose: food=* , but came up with:
So, the correct tagging for a restaurant and what is served inside is:
This is not so bad at all, because this scheme allows you to tag many more places where you can eat, but which are not considered a restaurant, like a cafe, bar of pub (or a railway station or book shop).
There are some curious constructions however, because to tag a Burger King (or any other fast food restaurant) you can do so in two ways:
By itself, using fast_food as a value for an amenity is rather strange, because to me, fast food is a type of food, belonging to cuisine, not an amenity! (Would you use highway=asphalt? No, of course not, because highway=* expects a function of the highway it describes, not its surface).
The addition of the cuisine=* in the last case is maybe not even necessary, as hamburgers are core business in any fast food restaurant.
Over the years the list of values to assign to the cuisine key has grown (and will keep to do so) and now (february 2017) we have two basic groups in the wiki:

  • 40 values for the type of food (like fish, meat, pizza, burger, kebab, soup, etc.)
  • 53 values for the ethnicity of the food (like italian, greek, chinese, mexican, etc.)

As values from both lists can be combined, this introduces a rich array of possibilities, but also adds confusion. For some people “eating Italian” just means having a pizza ordered, to others it is soup and pasta or a 5 course dinner in a restaurant.
I did some research on the different ways people have used the above tagging system to map restaurants and what you can eat. After all, it is likely that you can eat a variety of food in a restaurant, and that, in turn, requires multiple values to be assigned to a single key.

(note: there have been many discussions on the tagging list as well as numerous postings on the forums on the best way to add and handle multiple values for a single key. Most seen is that different values are separated by semi-colons as can be read in the wiki, but some people think you shouldn’t use multiple values )

Suppose that we allow 4 different values (out of 40) to be used for the type of food (like burger, chicken, donut and kebab), that would give us a maximum of 2 193 360 different combinations. Of course not all combinations make sense, I don’t expect fish-pancake-noodle-casserole to be a frequent combination.
Choosing from the 53 ethnicity values would even give much more possibilities, but, again, not all are to be expected.
I found (among many others) the following combinations (from both lists) in use:

  • chicken;kebab;fish_and_chips
  • pancake;friture;chicken;grill;breakfast;coffee_shop;beef_bowl;russian;fish_and_chips
  • burger;sandwich;pasta;pizza;ice_cream;chicken;coffee_shop
  • burger;sandwich;breakfast;sausage;local;noodles;pasta;pizza;chicken;diner;
  • burger;sandwich;local;chicken;fish_and_chips
  • bagel;breakfast;cake;coffee_shop
  • chicken;burger;grill;oriental;breakfast;pizza;hotdog;kebab;local
  • italian;indian;regional;mexican
  • fataya,sandwich_poulet,hamburgers
  • italian;creative
  • kebab;pizza;schnitzel;sausage;salad
  • indian;vegetarian;chinese
  • italian;pizza

I also found:

  • 짜장면,짬뽕,탕수육,간짜장,우동,짬뽕밥,잡채밥,육개장,잡탕,양장피등등중국요리
  • 早餐:蛋餅,蔥抓餅,饅頭,肉包,炒麵,豆漿,紅茶
  • 돈까스,피자,스파게티
  • Горячиеблюда,гарниры,закуски,салаты,_кампот

In the above list I have marked in bold type those choices that are not in any of the 40 food (or 53 ethnicity) wiki values (excluding the entries in non-Western script). In the current taginfo database there are 21878 occurrences of the cuisine=* tag. The one used most is cuisine=regional that is used 62291 times. But there are also 17849 occurrences of that key which appear only once, but every time with a different combination of values like I showed you above.
The last multiple value in the list above is italian;pizza which has been used 948 times. What exactly does it mean? Pizza is Italian so why bothering adding that also? A simple cuisine=pizza would suffice, or does it mean that you can eat all and every Italian food in a restaurant tagged in this way, but maybe with pizza as something special? I don’t know.

Usually, when a key=value pair occurs only once, it is considered likely to be a typing error (like cuisine=piZza or highway=terziarie) or a new value made up by the mapper (like cuisine=romanesc), but the small sample (taken from the full list of 17849 unique cuisine=* occurrences) above, are not typing errors, but taken from all the possible and valid combinations. How many such combinations are possible? Assume that we allow 2 choices from the ethnicity values and 4 from the food values, then we have a maximum of 53 x 52 x 40 x 39 x 38 x 37 = 6 044 900 160 possible values for the cuisine=* tag! (Yes that is: six-billion fourtyfour-million ninehundred-thousand and onehundred and sixty)

Which way to go?

I have seen proposals of adding the complete merchandise of certain shops to the OSM database. By doing so we would be able to query OSM for “the nearest shop where I can buy an ironing board”
To me that makes no sense at all, as there is no way of getting all that data reliable into OSM. And maintaining it would be an ever bigger challenge.

Should we try to do the same with restaurants and food?
Given the rather careless manner in which the multiple valued tags for cuisine have been used (a result from the database design we are using which allows for any combination of keys and values - in any language - without any error checking at all), I don’t see any usability soon for applications - based on what is in the OSM database - that can compete with what already is on the market for customers. Have you ever spoke to anyone who tried to find out where he/she would go for dinner tonight - including selecting what to eat - by using OSM?
One - fairly big - problem is that roughly one-half of the restaurants has no cuisine tag at all, making it useless for what you were trying to find out (“what can I eat?”).

I know that we can put anything in the OSM database, but we cannot put everything in it.
Let us focus on getting data (as much as we can) into OSM that turns it into a great map (that includes showing where I can find a restaurant), but shall we avoid creating a mediocre restaurant and food guide? now supports internationalization, geolocation in browser

dim 19 fév 2017 - 5:18

Keen to make it even easier to contribute to OSM, I threw a few pull requests at - the github repository behind the wonderful

Its now possible for someone to use the 'locate me' control when adding their business; a small but important improvement for mobile users.

iandees has also been kind enough to clean up a few existing pull requests around internationalization - now supports English, Portguese(Brazillian), and Italian. If you'd like to localize it, its really easy - just fork the github repository and create a new file in the locales directory.

There are a few other experiments for it pending, such as 'sync my business details from a facebook page I own', or 'upload details of 5+ locations from a CSV'.

Ultimately, I'd be keen to provide an experience similar to a 'manage my google listings' scenario - both google and facebook have seen a lot of uptake from business owners. While business owners dont have quite the same incentive with OSM, I am really keen to make it as easy as possible if they choose to publish to OSM.

There are a few other ideas in the works, like "Invite a business owner to share/update their details", or "check how my OSM listing appears on open data sites -, mapillary/openstreetcam, missing attributes, etc"

What do you see as the ultimate, simplest entry point to getting a business onto OSM with accurate, useful details?

(Semi) automating street name expansions

dim 19 fév 2017 - 1:34

I've been working on a JOSM script to expand abbreviated street names. There are hundreds (if not thousands) in the Plainfield, IL area.

This is extremely tedious work without so form of automation. So far I have reviewed every name change and it's been working awesome.

I wrote up instructions at the GitHub link above. Give it a try yourself or let me know if you find an area with a lot of abbreviated names.

Кнопка каждая важна

sam 18 fév 2017 - 22:45

На сайте новость: нажатие правой кнопки мыши на карте больше не выводит меню браузера. Теперь там меню сайта с традиционными для веб-карт пунктами: построить маршрут, посмотреть адрес, получить список объектов. Не нужно перетаскивать маркеры и не нужно целиться в кнопки со знаком вопроса или заметкой. Подсматривать адрес тайла и дёргать /dirty стало сложнее.

Все остальные веб-карты давно перехватывают нажатие правой кнопки. Google Maps его просто игнорирует, Яндекс.Карты тоже не откликаются (даже в редакторе, как ни странно), но двойное нажатие правой кнопки уменьшает масштаб, в противовес левой кнопке мыши. Так же ведёт себя новый сайт Карт Спутника.ру (в пятницу они обновили дизайн), но по одиночному клику показывает меню. Меню по правой кнопки мыши выпадает и у Bing Maps, самое красивое и полезное из всех: только в нём есть пункт «скопировать координаты».

Традиционно для нашего сайта, пул-реквест Дэна Стауэлла висел с августа 2015 года. Неделю назад Стефан Келлер нашёл его и написал, что ему часто жалуются на отсутствие всплывающего меню на За шесть часов решили все проблемы и вчера Том, наконец, решительно нажал кнопку «Merge».

В этом году сайт развивается быстрее прежнего: недавно улучшили оформление писем и ограничили размер пакета правок. Четвёртого января неожиданно и неожиданно быстро, всего за семь часов, на сайт добавили слой GPS-треков. Тот самый, да. Наконец, на этой неделе все сервисы переводили на Let's Encrypt: помимо прочих, SSL-сертификат появился у домена, так что короткие ссылки стали безопасными.

The OSM website now has a context menu (right-click menu)!

sam 18 fév 2017 - 18:27

It gives me great pleasure to announce that the OpenStreetMap website now has a context menu! Also known as a right-click menu:

You might not think this is big news, but I do. A few people asked for this feature in the past, and eventually I proposed some code for it. It took 18 months for the proposal to be merged into the website codebase - why? Primarily because OSM is built and run by volunteers with limited time, but also because my Javascript skills weren't quite up to adding the important polish and tests that are needed for production-ready code. A million thanks to Tom Hughes for improving my not-quite-finished proposal, and for all the feedback that helped me understand how to do things right.

Visit to Mbale university

Yesterday was a great day as I had chance to be a part of the mapping work shop held in Uganda Christian University Mbale, Uganda. We had a chance to be reminded of the good mapping practices and tips and also introduced to validation. it was a great excitement to us all learning how to validate and giving feedback to people who mapped the tasks. All thanks to Mr. Kateregga Geoffrey for the great work done.

Новая резалка по-новому режет

sam 18 fév 2017 - 10:14

Пару недель назад Йохен Топф рассказал про новую функцию osmium-tool: режим extract для вырезания областей. Диаграммы в заметке показывают, что osmium вырезает в два-три раза быстрее, чем osmconvert. То есть, как когда-то osmconvert заменил osmosis, потому что был не в пример быстрее, так теперь osmium, кажется, может заменить его.

Я решил сравнить утилиты чуть тщательнее и взял файл планеты в pfb от 30 января. Сделал его копию в o5m — формат стал популярен именно из-за osmconvert, который обрабатывает его чуть быстрее других. И поскольку osmuim не умеет писать в o5m, а только читает, сравнил скорость преобразования обратно в pbf:

33 минуты против 86! Серьёзная заявка на победу. Причина проста: osmium многопоточный. Пока osmconvert вяло крутит 70% одного ядра, его конкурент задействует 265%, то есть, около трёх ядер. Отсюда и разница в 2,6 раза.

Для проверки вырезания регионов я взял Мюнхен, который в pbf займёт примерно 200 мегабайт. Вырезал по прямоугольнику и по полигону из 1200 точек. У обоих утилит есть настройка полноты вырезанных данных: простой режим сохраняет только те точки, что попали в область обрезки. Сложный «complete ways» досыпает точек за пределами области, которые принадлежат линиям изнутри её. То есть, в итоговом файле не будет неполных линий. Режим «complex ways» («smart» в osmium) дополнительно сохраняет целостность мультиполигонов.

Как видно, при работе с pbf osmium в полтора-два раза быстрее osmconvert. Разумеется, за счёт многопоточности. Но с o5m работать в несколько потоков не получается, поэтому столбцы красного оттенка отличаются несильно. Как видно, нет такого режима выгрузки, в котором osmium не превзошёл бы osmconvert.

Превосходство будет ещё заметнее, если не читать файл планеты для каждого региона отдельно, а вырезать несколько регионов за раз. Да, osmium это умеет. Правда, требует очень много памяти: Йохен советует сначала вырезать континенты, затем группы стран и так далее. Понадобится написать файл конфигурации, как описано в документации. В январе на многопоточное одновременное вырезание регионов перешли в Geofabrik, ускорив подготовку выгрузок с 10 до 4 часов.

А теперь непонятная диаграмма, дополняющая предыдущую:

Утилита time, которой я замерял время работы, выдаёт «real time», время от запуска до остановки, и «user time»: время процессора, затраченное исключительно на приложение. И если я правильно понимаю, osmium оказался менее оптимизированным, чем osmconvert, но он эффективнее использует ресурсы компьютера.

Итак, osmium может заменить osmconvert, и почти всегда окажется быстрее. Кроме того, он позволит снять зависимость от формата o5m, который хоть и поддерживается osm2pgsql и другими программами, основанными на libosmium, но требует больше места и дополнительной конвертации. Что с другими приложениями из комплекта osmctools?

Osmupdate удобен простым обновлением выгрузки или файла планеты. Достаточно указать в параметрах имя существующего и нового файла, и получим данные из OpenStreetMap на минуту запуска. Умеет ли подобное osmium-tool? Нет, к сожалению. Но osmupdate — лишь надстройка над wget и osmconvert, скачивающая файлы репликации и передающая в osmconvert для объединения и применения к исходному файлу. Osmium-tool может делать всё, что умеет osmconvert, и возможно слегка переписать osmupdate, чтобы он запускал его вместо osmconvert (и заодно curl вместо wget). Или встроить подобную функциональность в osmium — увы, пока этого никто не сделал.

Но в плане сравнения производительности можно посмотреть на время обновления файла планеты диффом за одни сутки:

Как и обещала справка osmconvert, файлы в формате o5m он обрабатывает быстрее. Как показали прошлые замеры, osmium работает быстрее независимо от формата.

Заменой для osmfilter должен стать osmium-filter. Мне удалось его скомпилировать, но я так и не разобрался в его формате запросов. Инструкция из readme не помогла. Поэтому сравнивать пока нечего. Увы, именно osmfilter требует формата o5m, поэтому если в ваш процесс обработки данных входит, например, фильтрация береговой линии, полностью снять зависимость от o5m не получится.

И ещё одно может стать препятствием: пакет osmctool очень редко обновляется, и потому он достаточно свеж во всех дистрибутивах Linux. А режим extract в osmium-tool появился только в версии 1.5, которая на этот момент загружена только в репозитории Debian (jessie-backports) и, конечно, AUR для Arch Linux. В Fedora устанавливается версия 1.4.0, а в Ubuntu — вообще 1.3.1. Для этих систем придётся собирать osmium-tool из исходников.

Тестирование проводилось на среднем по характеристикам ноутбуке Asus с восьмиядерным i7-4700 @ 2,4 ГГц, 12 гигабайтами памяти и каким-то HDD.

Chasing All Hallows through Gedling

As best as I can work out, the first photo that I took of All Hallows Church, Gedling was on September 19, 2016 from near the top of Chatsworth Avenue looking north north east:–

September 21 2016 saw me receive the chilling news about The Chancel Tax.

Throughout the rest of September & October I kept my head down & mapped to the West then North. By 23 November it was Arnold Lane outside Scot Grave Farm heading south-east and suddenly we caught a distant view of the church again:-

Finding dragged nodes

ven 17 fév 2017 - 14:18

Stumbled upon this mistakenly dragged node thats been hanging around Sheffield for the last two months. Considering its not fixed despite having a highly active mapping community, wonder if some tooling could have helped flagged this to local mappers sooner.

Ideas on how to prevent such edits in future? Any existing QA tools that highlight this?

Mennoniten in Bolivien mappen ihre Heimatgemeinde mit lokaler Kenntnis 1

  • Im Forum wird darauf hingewiesen, dass Altglascontainer zum Einwerfen von Flaschen und Konservengläser ausschließlich mit recycling:glass_bottles=yes zu taggen sind. Grund: Das häufig zu sehende einfachere Tag recycling:glass=yes schließt auch Glassorten ein, die dort nicht eingeworfen werden dürfen.
  • [1] Die Mennonitengemeinde Colonia Pinondi im bolivianischen Tiefland hat damit begonnen, ihre Gemeinde auf OSM zu kartieren (via OSM Cochabamba). Wir finden, ein gutes Beispiel für alle Mennonitengemeinden weltweit.
  • Martijn berichtet von seinem Besuch eines OSMTime-Events in Cluj, ein Mappingevent, das einmal im Monat von Beata Jancso organisiert wird.
  • Mapbox interessiert sich neuerdings für Straßen als Flächen. PlaneMad vom Mapbox Data Team verweist in Zuge dessen in seinem Benutzerblog auf Testdatensätze als Mapbox Vector Tiles, GeoJSON und die zugrunde liegenden Daten in der OSM-Dev-API (d.h. die Daten sind nicht in der produktiven OSM-Datenbank!).
  • Für einen Vorschlag für das erweiterte Taggen von Strommasten wartet Jherome Miguel noch auf Kommentare.
  • Joost Schouppe fragt auf der Mailingliste Tagging, wie man Kopfweiden taggen soll und sucht nach englischen Begriffen.
  • Die deutsche Mailingliste diskutiert über das Routing von Wegen, für die – z.B. in Zoos – Eintritt verlangt wird.
  • Martin Koppenhoefer beschwert sich darüber, dass das Tag information=trailblaze nach einer nicht einstimmigen Diskussion im deutschen Forum aus den Map Features entfernt wurde.
  • Mit der Macht kommt die Gefahr. Wer Koordinaten mit Level0 bearbeitet, sollte umsichtig sein.

  • Christian Bittner hat einen Artikel zu OSM in Israel und Palästina geschrieben und darüber berichtet. Er stellt unter anderem fest, dass den OSM-Daten und den daraus abgeleiteten Karten eine besondere Bedeutung in diesem politischen Konflikt zukommt („ground truth“). Da es keine open-access-Publikation ist, versendet Christian das PDF gerne auf Anfrage per Mail.
  • Ediyes berichtet über die Erfassung ihrer Heimatstadt Andahuaylas, die bisher praktisch noch nicht gemappt ist.
  • Peter Barth resümiert im OSM-Blog über die Projekte, welche im letzten Jahr am Google Summer of Code teilgenommen haben. Da sich OpenStreetMap auch in diesem Jahr beworben hat, sollten sich interessierte Studenten die Ideenliste im Wiki anschauen.
  • Martin Dittus (dekstop) stellt in seinem Benutzer-Blog die Ergebnisse seiner Untersuchung vor, wie Feedback über den Tasking Manager die weitere Aktivität von Neulingen beeinflusst. Leider legt er nicht offen, nach welchen Regeln er die einzelnen persönlichen Nachrichten klassifiziert hat.
OpenStreetMap Foundation
  • Am 12. Februar sind zahlreiche Dienste der OSMF mit neuen SSL-Zertifikaten von Let’s Encrypt ausgestattet worden, welche z.B. sowohl für als auch gültig sind, sodass man bei beiden Versionen (openstreetmap / osm) ein gültiges Zertifikat enthält. (Quelle: Chef-Repository der OWG)
  • Am 11. und 12. März finden die Chemnitzer Linux-Tage statt. Neben einem Stand sind auch zwei OSM-Vorträge in das Programm aufgenommen wurden. Holger Dieterich vom Verein Sozialhelden stellt passend zum Motto „Barrieren einreißen“ das Projekt vor. Thomas Graichen zeigt den an der TU Chemnitz entwickelten Indoor-Campus-Finder auf Basis von OpenStreetMap.

  • Ilya Zverev hat einen Pull-Request für die OSM-Website gestellt, mit dem man sich künftig mit seinem MAPS.ME-Benutzerkonto bei OSM einloggen kann.
  • Peter Liu erklärt, wie er Satellitenbilder und Höhendaten mit Three.js zu einer interaktiven 3D-Karte verbunden hat und plant eine ähnliche Demo für Unity.
  • Das Verhalten von osm2pgsql wird sich in der nächsten Release ändern, wenn nicht über die Kommandozeilenoption -d eine Datenbank angegeben wurde. Dies ist eine Vorabinformation, damit Entwickler bereits jetzt die entsprechenden Befehle anpassen können.
