OSM Tags - oder auch nicht?

Posted by R0bst3r on 21 April 2015 in German (Deutsch)

Ich bin zur Zeit ein bisschen amüsiert und auch manchmal erstaunt, was man nicht alles in der OSM Datenbank über taginfo findet:

  • Freimaurer Pentagramme
  • Relationen über Aussenwände von Häusern
  • Toiletten mit mail=yes tags
  • Private Tags ala "Created = by me", oder hier wohnt Nachname = Vorname
  • Häuser die Schatten werfen
  • Leicht übertriebenes wie, highway=residential, street=yes,residential=yes,ist_wirklich_ne_strasse=yes
  • Leicht untertriebenes wie hotel = unknown
  • Überwachungskameras ohne Elektroschocker und Wasserkanonen
  • Hotels deren Anzahl an Betten genauestens gemappt ist
  • Immobilienmakler, die gleich auch noch die Verkauspreise reinschreiben
  • Dokumentation der Anzahl der Jungen und Mädchen im Kindergarten
  • Dokumentation der NeuInfektionen im Krankenhaus
  • Tags zum Dokumentieren der Anwendung von Pestiziden und die erwartete Ernte
  • Einiges an fremdsprachigen Tags ala "pablaespanol = awaIdochnet"
  • Viel Nummer Tags ala "key = 456545556/4562"
  • Und jede Menge nonsense Tags ala "lqqw=ewj"

Jedem, der das auszuwerten versucht mein herzliches Mitleid! Schade, dass man da nicht mal aufräumt und es auch nicht darf. So ist leider vieles was einmal getaggt wurde nur nutzlose Information.

Missing boundaries

Posted by kjordahl on 20 April 2015 in English (English)

Several important public land areas in the Inland Northwest are entirely missing from OSM:

  • Idaho Panhandle National Forest (jointly administered Coeur d'Alene, St. Joe, and Kaniksu National Forests)
  • The portion of Colville National Forest east of the Columbia River
  • Salmo-Priest Wilderness

All of these are available from forest service data.

Missing state park boundaries include:

  • Mount Spokane State Park (Washington)
  • Priest Lake State Park (Idaho)
  • Priest Lake State Forest (Idaho; exists only as a point)

spam users ☹

Posted by scruss on 20 April 2015 in English (English)

I dunno what it is about a certain kind of solar power sales person, but they're all about the spam. In trying to find details for tagging solar hot water heaters, I found a couple of no-edit accounts with word-number-word algorithmically-generated names: push36queen and cry3dime

There are probably more.

If you do happen to be looking at how to tag solar hot water, this looks about right: Node: 2671563575

Netherland housenumber evaluation available

Posted by okilimu on 19 April 2015 in English (English)

Netherland housenumber evaluation available

Data source for the Netherland housenumberlists

A nationwide housenumberlist is available together with a lot of more data at NLExtract. Fortunately, they deliver the content with easier access as a NLExtract database, updates come roughly once in a month.

After installation of the database locally, i export only the housenumberlists and import them into the housenumber evaluation database on my webserver

Up to now, my plan is to update the official housenumberlist about 4 times in a year.

Numbers about all housenumbers in Netherland

After filtering duplicate housenumbers, there are 8.254.736 housenumbers in 393 municipalities in Netherland.

Overview about the last nationwide housenumberlist evaluation

I have some municipalites, which still don't work automatically in the evaluation process (different municipality names to the OSM names), so i evaluated 387 municipalites with officially 8.020.125 housenumbers and found 7.736.631 housenumbers in OSM (thats 96.47%). Another 202.863 housenumbers are not on the official lists, but exists in OSM.

Graphical overview of the evaluations

Best starting point should be the Map Overview.

On the map, you can click in a municipality area and get the evaluation overview for the municipality and most times also for a subarea within the municipality. The names have a link to switch to the table view of the evaluation with detailed information for every streets and its housenumbers.

Select a municipality for detailed information

An another way to select a municipality evaluation can be found at the municipality overview page.

At the top, click on „Netherland“, then you come to the starting point for all municipalites, which are sorted by dutch provinces. When you click on a muncipality name, you come to the page, where you select the municipality evaluation (first line in the pull down list) or one, some or all of its subarea evaluations (if the municipality has subareas in OSM).

Below the selection, you can change some settings for the evaluation page, but the standard settings should work first time.

Click on „start“ to show the evaluation table view page.

Evaluation table view page

In the left top area, you get the information, when the evaluation run last time and which timestamp the OSM data had.

In the right top area, you find information about the source of the housenumberlist data, a link to the data source license text and below some links for special features, which are not important for first time.

The only valuable link at first time is the link after the text „in OSM still missing housenumbers:“ where you get all housenumbers, which are still missing in OSM, together with its coodinates. The page can be saved locally as a file with .osm extension and can be opened within Josm.

Below the header area, a table with all streets will be showed and for every street you find the housenumbers, which are in the official list and if they also exists in OSM, which are still missing and which are only in OSM. The last ones could be typing errors in an osm editor, but they also could be very new housenumbers, found by osm users.

At the bottom of the page, you find the sums of all columns.

With the standard settings, the streets have a link to show on the web page and all housenumbers in columns „identical“ and „only in osm“ have links to view on web page or in the popup dialog the link to show the housenumber directly in Josm (the editor must be running and accept remote control).

Special evaluation situation in Netherland

The standard evaluations works in the way, that a housenumber together with its street name will be checked between the official list and the data in OSM.

In Netherland, a lot of streets are differently written in the official lists versus in OSM, so for example, the street „Burgemeester Gerritsenstraat„ in OSM, has been written as „Burg. Gerritsenstraat“ in the official list. This example can be viewed on the Sluis evaluation page.

An earlier housenumber evaluation for Netherland was not very sucessfully therefor, but a Dutch OSM Mapper gave me the hint, that in Netherland, the postal code together with a housenumber is unique (thanks a lot to Johan!). After some time of work to enhance the evaluation engine for this case, the evaluation works now very fine.

Some bugs on the evaluation table view page

Some side effects for the new added postal code in evaluation process are still active. In the example above, you will find in the evaluation page two lines for the one street. One line with the OSM version of the name and all housenumbers only appear in the column „only in osm“ (this is wrong) and in a second line, the official name appears and has correctly filled columns. This effect doesn't effect the evaluation result data, but is a little bit confusing. I try to fix this shortly.

Another point is, that normaly a housenumber will be showed only one time in a street line. If the streets exists more than one time in the muncipality area, like „Dorpstraat“ in the Sluis Evaluation, you see some housenumbers more than one time. This occurs, because the Dorpstraat exists in several subareas of the municipality and every „Dorpstraat 1“ has a different postal code. I must change something to show this different streets more transparently, for example one line for every streets together with its postal code?

Another nice situation can happen (seen in Leiderdorp: in street „Simon Smitweg“, the housenumber 1 can be seen both in column „identical“, but also two times in column „only in OSM“. In this case, three parking areas have this address, but with different postal codes. In the official list, there is only one housenumber with one postal code. I assume, this is an error in OSM data.

Evaluation rhythm for the future for Netherland

I still didn't activate it on a regularly base. At next Thursday (23th of April), i try to let it run to find out, how long it will run completly for Netherland on the evaluation server. After the experience, the rhythm and perhaps different update times for the provines will be published on the housenumber evaluation starting page.

In the future, i try to add an „start instant evaluation“ button on the evaluation table view page to request a new evaluation immediately. But i must be aware, that some OSM guys could press this button too often, so i have to take a litte care on this feature ;)

A word for language localisation

On most of the housenumber evaluation pages, you can select the language in the upper right corner of the page (you only need to set it once). Up to now, there are only the languages german, english and brazialian portugese available. It you want to add another language, like dutch or french, please contact me, i show you the way to localize the dialog texts in a text file.

End of the story

I hope, this evaluation for whole Netherland will help you a little bit, when you add or change housenumber data in OSM in Netherland.

If you find problems or errors that are not described above, let me know. You can send me a OSM PM to user Okilimu or a mail to strassenliste(at) Change (at) with @ in the mail address field.

New Orleans building import progress

Posted by coleman on 19 April 2015 in English (English)

Lately I've been assisting with the in-progress New Orleans building import. So far I've imported several sections to finish out East New Orleans, and had minimal issues getting everything loaded. That part of town had maybe 3 existing buildings to deal with conflating during the process.

Now that I've reached the navigation channel, I've moved on to verifying some of the hundreds of other sections imported by other mappers. Some of the central city segments look like they had some significant overlap with existing data, so could use a second set of eyes. Many of those will require local expertise to officially confirm, though.

Update Tiroler Hausnummerauswertung

Posted by okilimu on 19 April 2015 in German (Deutsch)

Tiroler Hausnummerauswertung


Nach den Problemen in den vergangenen Wochen wurden jetzt auch die Auswertungen für die Gemeinden in Tirol umgestellt auf die neue Version der Auswertung.

Zur Tiroler Auswertungsübersicht in der Karte

Trioler Gemeinden mit unklaren OSM-Hausnummern

  • Amlach Hier scheint die Zuordnung zur "Straße" Amlach falsch zu sein. In der offiziellen Hausnummerliste gibt es keine Hausnummer mit diesem Straßennamen, sondern die Zuordnung zu verschiedenen Straßen. Diese Straßen existierten auch auf, hier ist die Straßenangaben zu prüfen und ggfs. zu korrigieren.

  • Hart im Zillertal Auch hier sind vermutlich die Straßenzuordnungen falsch, bitte prüfen und korrigieren.

  • Fügenberg Auch hier vermutlich veraltete Straßennamenzuordnungen.

  • Hall im Tirol, Subbereich Thaur Hier gibt es vermutlich einen Exklave-/Enklavefehler. Ich habe einen OSM-Mapper angeschrieben, der eine Exklave von Thaur auf Haller Gebiet eingetragen hat und die in der Thaur-Relation richtig ist. Dieses Gebiet ist aber nicht in der Haller Relation als inner Element eingetragen. Daher wird in der Hausnummerauswertung versucht, das Thaur Subgebiet auszuwerten und es kommen natürlich keine Hausnummertreffer.

  • Unterperfuss Der einzige Straßenname Unterperfuss wird in der offiziellen Liste am Ende mit ss geschrieben, in OSM aber mit ß.


Die österreichischen Gemeinden werden Montags und Freitags ausgewertet und stehen um ca. 14h zur Verfügung.

Tiroler Auswertungsübersicht

In Tirol gibt es 279 Gemeinden, in der Hausnummerliste sind insgesamt 186.131 Hausnummern aufgeführt und davon sind 174.258 Hausnummern in OSM enthalten und entsprechen der Liste, das entspricht einer Abdeckung von 93,62%.

Darüber hinaus gibt es weitere 6.717 Hausnummern, die nur in OSM vorhanden sind,.

US County Roads (from residential to track)

Posted by Aury88 on 18 April 2015 in English (English)

Hello everyone,

some days ago I began to (try) improve the mapping of the US and in particular I'm focusing in the correction of the agricultural roads that are currently mapped with a wrong tag highway = residential.

My work does not touch other tags (in particular those related to the given TIGER) to allow the backup of the original data in case I make some very serious errors (also TIGER has many: wrong tag, wrong geometry, probably wrong I have to put in effort to make the situation worse ).

Another thing that I try to do is reduce the number of unnecessary nodes (I saw very straight roads with hundreds on sorted nodes), which greatly complicates the workflow as it is easy to create conflict if my work touches streets with nodes outside the downloaded area (in JOSM).

Last point is the addition of a surface tag because not all the agricultural roads are equal and some of them, being paved, may allow the use as a useful shortcut and this is where I have a problem in distinguishing the material of the road.

For example, I can not understand what surface is that of this and many other agricultural roads.

Can you help me?

Thank you.

Where do you swim in OSM?

Posted by Alan Bragg on 17 April 2015 in English (English)

I want to identify where you can swim in a body of water. I've found two ways that are acceptable to the JOSM Validation routine.

  1. Create a beach polygon (natural=beach) and add (sport=swimming), I don't think anyone swims in the sand.

  2. Create a polygon in the water (leisure=swimming_pool) and add (sport=swimming), I don't think anyone builds a swimming_pool in the ocean. Of course you can swim in a pool of water.

How do you identify where you can swim?

Недельное задание 5: статистика

Posted by edward17 on 16 April 2015 in Russian (Русский)

Прошлая неделя была посвящена нанесению лесов Полесья.

Собственно, графиков в этот раз всего два: площадь лесов (natural=wood) и площадь лесохозяйств (landuse=forest).

statistic statistic

Как видим, обрисовано было 500 (!) квадратных километров зелени.

Кроме того, из графиков следует, что площадь полигонов landuse=forest немного уменьшилась. Однако она всё равно в три раза больше, чем площадь natural=wood. Сомневаюсь, что такие огромные территории действительно используются для ведения лесного хозяйства (например, получения древесины или бумаги). Буду рад, если кто-нибудь поделится статистической информацией по этой теме. Эта ситуация хорошо иллюстрирует неоднозначное толкование и использование этих двух тегов в Украине. Как, впрочем, и во всём OSM.

И несколько сухих чисел об этой неделе:

  • 6 участников
  • 41 пакет правок
  • ~28 000 изменений объектов

Как написал Runge (автор стиля MapSurfer.NET), сейчас обновляются тайлы этого стиля на зумах 12-8. Надеюсь сделать картинку-сравнение (было-стало) на его основе.

P. S. Высказывания о значении тегов natural=wood и landuse=forest - личное мнение автора, оно может не совпадать с вашей точкой зрения ;)

На этой неделе: боремся с ошибками в роутинговом графе.

  3. Сайту чуть больше года.
  4. Трафик 30-40 чел в сутки
  5. Около 120 компаний уже зарегистрировались
  6. Около 280 объявлений уже подано

Прикреплю скрин роста трафика за год.

Прикреплю скрин роста трафика за год -

Как видно рост есть, плавно, медленно но есть. Стройка не так легко идет как остальные проекты. Буем двигаться дальше.
