You mapped the clear white objects as buildings, correct, but ignored the brownish/gray rectangular objects.
They ought to be mapped as well as a building.
Best regards and keep mapping
Frans S (2025-10-06 09:10:28+00:00): Thank you for mapping. You have correctly identified the location of most objects and mapped. 
However, You often included the shadow of a building into your mapping.
Don't map open objects (only walls visible) as a building. 

Reminder: Please be sure to square all rectangular buildings with the Q key

Antonio Eugenio Burriel (2026-07-01 18:00:51+00:00): Buenas tardes Jordi,

no estoy de acuerdo con esta afirmación:
https://wiki.openstreetmap.org/wiki/Key:turn#Indicated_turns_by_lane
Jordi MF (2026-07-01 19:00:33+00:00): Hola Antonio,

Tendría que revisar la edición con el ordenador, pero intentaré explicar los criterios que seguí y, así, me podrás corregir mejor. Si no recuerdo mal, los criterios que seguí en esta edición fueron los siguientes:
1) Situé el inicio de los carriles de desaceleración lo más cerca posible del final de la línea discontinua (es decir, el último momento en el que el coche puede tomar la salida).
2) Conecté el final de los carriles de aceleración con la carretera nacional en el punto en el que se termina el carril de aceleración.
En el caso 2 no debería de haber incongruencia con el número de carriles yblas indicaciones de dirección, ¿no?
En el caso 1 puede que haya tramos en los que no esté representado un tramp del carril de desaceleración, ¿verdad? En esos tramos, entiendo que tú añadirías la etiqueta "turn:lanes:forward=* o "turn:lanes:backward=*" y yo lo quité. Creo que ese es el problema que ves. Este cambio lo hice después de discutir con otro usuario de la comunidad española sobre los carriles de aceleración y desaceleración. Me hizo entender que los carriles de aceleración y desaceleración no debían de computar como carriles de la carretera principal.

Intentaré explicarme. Por ejemplo, si añadimos el número de carriles en la carretera nacional teniendo en cuenta el carril de desaceleración, la base de datos interpreta que la carretera nacional se convierte en una carretera de tres carriles (el carril que viene de cara más los dos carriles que irían en el sentido de la conducción). Si se añaden las señales "turn:lanes" + un carril extra (lanes:forward=2), la base de datos interpreta que la carretera nacional se convierte en dos carriles de circulación en un sentido. Aunque tenga los turn:lanes=*, los navegadores como OsmAnd le piden al conductor que se sitúe en el carril de la izquierda. Pero, para el conductor, no tiene ningún sentido porque la carretera sigue siendo de un solo carril; lo que tiene al lado es un simple carril de desaceleración.

Por eso, eliminé esa información. Antes, yo no lo veía así. Si estás seguro que es un error mapearlo así, no intentaré defender más mi postura. Incluso puedo corregir esta manera de mapear. Pero, como es un tema muy recurrente, antes de volver a cambiar mi modo de editar, trasladaría esta duda al foro de la comunidad para ver las psoibles ventajas de hacerlo de un modo u otro.

Estamos en contacto y gracias. Saludos,
Jordi
Antonio Eugenio Burriel (2026-07-06 16:08:55+00:00): Buenas tardes Jordi,

totalmente de acuerdo con los dos criterios, es algo que en mis primeras ediciones no lo hacía bien y poco a poco lo he ido rectificando, aunque se me habrán quedado montones de carriles por rectificar.

Mi objeción viene con el tramo que incluye el carril de aceleración, ese carril se tiene que contabilizar y marcar como tal (slight_right para deceleración y merge_to_left para incorporación).

En tu edición descontaste estos carriles de la etiqueta lanes (2 carriles en lugar de 3), en un caso mantuviste las etiquetas turn:lanes para 3 carriles, creando una inconsistencia y en otro las eliminaste.

La documentación que te he enlazado explica cómo se contabilizan estos carriles, te agradecería que la revises de nuevo para quedarnos tranquilos, mi lectura es que sí se contabilizan.
Jordi MF (2026-07-06 22:04:30+00:00): Hola Antonio,

He realizado un cambio para saber si te he entendido bien y es la forma que consideras correcta. Antes se seguir con más cambios, ¿podrías revisar este?

Saludos
Jordi MF (2026-07-06 22:09:39+00:00): Perdón, me he confundido con "right" y slight_right". La vía que he corregido es esta: https://www.openstreetmap.org/way/24004567
Antonio Eugenio Burriel (2026-07-07 12:10:25+00:00): Buenas tardes Jordi,

en mi opinión el etiquetado para el segmento corregido debería ser: through|slight_right puesto que el único carril que permite la salida es de deceleración, más a la derecha.
through;slight_right tendía su cabida en el segmento anterior para señalizar que el carril permite continuar tanto al frente como salir de la vía.
https://wiki.openstreetmap.org/wiki/Key:turn

Luego está el tema del eje de la vía, que lo has ubicado en el eje que separa ambos sentidos de la marcha cuando debería estar en el eje geométrico de la calzada:
https://wiki.openstreetmap.org/wiki/Lanes

O  bien utilizar la etiqueta placement para indicar el eje de alineación:
https://wiki.openstreetmap.org/wiki/Key:placement
Jordi MF (2026-07-08 12:26:12+00:00): Perdona Antonio, no estoy teniendo mucho tiempo libre. Cuando pueda, haré las correcciones necesarias si no las has hecho tú.

Sobre el uso de 'through;slight_right', lo hice porque hice caso a las señales del suelo y mientras la incorporación al carril de desaceleración está permitida.
Antonio Eugenio Burriel (2026-07-09 16:18:33+00:00): Agradezco tu tiempo Jordi,

A67-A67 (2025-09-28 12:48:40+00:00): Deze wijziging is begrijpelijk, maar incorrect. Omdat Landal in dit park een afwijkende nummering aanhoudt dan de officiële huisnummers, zijn de Landal-nummers in de tag addr:housenumber:landal toegevoegd. De tag addr:housenumber is voor het officiële huisnummer (614).

Can you review my work once it is online on the map ?
And Thanks again.
ilias_ (2025-10-08 11:44:36+00:00): Hi Small Rider,

Don't worry, we've all started somewhere and we've all learned to use OSM. Your help editing Tanger is extremely valuable.

As per the roundabout and the bus relations, I'll explain it to you.

When editing such a roundabout, it's tricky because you have to watch out for bus routes which go through it. First, you delete the roundabout from its relations in order to draw a new roundabout. Next, you have to "split" parts of the roundabout at places where the bus route passes.

To split a way (a line), you simply click on a point, and click on "X". That will split it. You can then add the desired parts to the bus routes.

This has to be done because if you don't, you'll add the whole roundabout to the bus relation (which is what you did), but a bus doesn't go around the whole roundabout, it only goes straight or turns for example. 

I'm here if you have any questions. Welcome to OSM.

tastrax (2025-09-27 07:50:25+00:00): Hi folks FYI - Phone numbers in Australia should be added to OSM according to the following format with the country and regional code +61 x xxxx xxxx, +61 xxx xxx xxx for mobiles or use the phone:AU key if a 1300 or 1800 number.
For freecall numbers that work whilst overseas (ie 13 13 13) use +61 XX XX XX as per the wiki guidelines https://wiki.openstreetmap.org/wiki/Australian_Tagging_Guidelines/Australian_features#Phone_Numbers .  I have just updated a recent addition that you made to OSM – Cheers
MassCartog (2025-09-24 12:56:37+00:00): Hi welcome to OSM. It seems like this road exists on the ground still. Why did you remove it from OSM? 

Is the road private? abandoned? just closed to the public but open to service vehicles? Is it just gated off?
EKelsey108 (2025-09-25 11:44:50+00:00): Road has been closed for 9 years and in the process of reclamation.  

Having it on a map adds to confusion and illegal off road driving, causing to road to remain on the ground.
MassCartog (2025-09-25 17:20:13+00:00): Hi, thanks for the response. On OSM, we do not removed features if they exist on the ground. If it exists on the ground, it is valid data regardless of a feature being public or private, designated or informal/illegal/unauthorized. Even decommissioned Road/trails that still exist should not be removed. Removing them is actually considered vandalism.

The correct way to handle this is to use OSM's tagging system. access=no would be appropriate if the feature is closed to the public. Once this is done, services that do use OSM data will reflect that and specify their access, and not route anyone that way.

You can add fences for barriers if those exist on the ground to block access to this road. 

Also look into Lifecycle prefix's for the correct way this is handled on OSM.

dknelson9876 (2025-10-11 17:37:11+00:00): Hi Smaug7,
Welcome to OSM and mapping in Utah! We're happy to have you. Because of our slightly unusual street names here in Utah, we have a specific page on the wiki about it (https://wiki.openstreetmap.org/wiki/Utah/Naming_Conventions). Specifically, the "N" prefix that you added to the street in this changeset is already captured in the name:full=* tag, so that the most common name=* tag can match what is visible on the street sign. It would be great if you could change this back (and the other nearby streets), or I am willing to do it for you if you ask. Feel free to ask if you have any questions! We can always use more people contributing to the map.

flohoff (2025-10-04 06:56:23+00:00): Dann wäre das vehicle=destination nicht access=private. 
Und den Privatweg könnte man als operator:type=private noch taggen.

"Durch" ist das gegenteil von "Anlieger frei" und "fahrt" ist fahren - geht also nur mit fahrzeugen. 

Also ist das richtige mapping des access tags ein vehicle=destination.

Denn ich darf nach Schild "Durch gehen" und auch "Rein fahren".

access=private ist da ein ziemliches Overblocking.

user_5359 (2025-09-24 07:58:58+00:00): Welcome to OSM! Thanks for your addition!
Please notice we use mostly lowercase words for our keys.
Udarian (2025-09-24 00:53:05+00:00): This is very likely some kind of vandalism as it adds allot roads with some of them dragged to end across the world; if I was being charitable this was an attempt to add historical features with some  dragged nodes. But even then the historical tagging is not present.
Keith Lewis (2025-09-24 00:55:33+00:00): something messed up in JOSM on upload and I'm not sure how to fix it...
Keith Lewis (2025-09-24 00:56:00+00:00): it conflated my edits with others in China.
Udarian (2025-09-24 00:59:23+00:00): then why are there dragged nodes from Canada and Europa? 
There are also ways like https://www.openstreetmap.org/way/1432435588 that cross highways, that are not on imagery available in iD and not tagged as a bridge or tunnel, or even layers.
Udarian (2025-09-24 01:05:40+00:00): also looking further into the changeset there are source:name=* tags that imply google was a source for at minimum part of this as we cannot use google maps as a source for this OSM changeset and we are not allowed to use google as a source as their license is incompatible with the OSM license.
Keith Lewis (2025-09-24 01:06:12+00:00): The only ones I had seen offhand were in China.  I stopped it before it caused any further damage. Again, they weren't dragged.  I created the nodes in JOSM.  It seems that node IDs may have been duplicated.  It's the only explanation I can guess.  As for the ways that cross highways, this was still a work in progress that I was cleaning up, but I halted the upload when I saw the stretched nodes.
Keith Lewis (2025-09-24 01:22:11+00:00): None of the data here was sourced from Google, The source:name you are referencing was a private blog.  The title of said blog merely contained the words Google Maps.
