“Tagging for the renderer” is a phrase commonly used in the OpenStreetMap community to mean specifically the bad practice of using incorrect tags (or otherwise skewing the data) for the map features, so that they show up in the mapper’s renderer of choice. Such tagging goes against the basic good practice principles.

Of course, adding correct data to the map is perfectly fine, even when it is motivated by a desire to make the map look better (e.g. more accurate) in one particular renderer. The phrase is confusing, and it has been suggested that it would be more accurate to speak of “mistagging for the renderer” and “lying to the renderer”. However, “tagging for the renderer” is the most widely used variant.

Using correct tags to get something rendered is good, using tags mismatching reality to get something rendered is bad. For example, mapping industrial area as landuse=industrial so it will appear on map is fine. Mapping nature reserve as landuse=industrial so it will be noticeable on map is wrong.

(this is wiki so feel free to improve it)

in introduction in osm.wiki/w/index.php?title=Tagging_for_the_renderer&diff=2830085&oldid=2689528 if it was unclear

lets see whether it will survive (I tried rename earlier)

There’s a saying in a certain article on the OpenStreetMap wiki that “tagging for the renderer” is equivalent to “lying to the renderer.”

no, it does not

A misunderstanding comes when people say that you shouldn’t tag something “for the renderer” even though the tags being used are accurate and not misleading. For example, if a specialist map renders a particular specialist tag (e.g. the details of power plants) then using the tags the renderer understands is a perfectly reasonable thing to do

The fact that OpenStreetMap data is used in such military applications raises important questions.

note that in this specific case it was used in ad

maybe because it is a proof of concept and actual software is not developed yet or maybe because actual design of interface is a secret, so they replace it with substitute

(though OpenStreetMap is also used in actual military applications, in actual war zones - just it is not such case)

My edits are not git commits.

AFAIK noone was claiming so and it such confusion was not a reason for adding this display

Well, “maybe this may data will be used by invading Russian army” is for me one of very few negative effects of mapping high quality data in OpenStreetMap.

Though I would count “it will make shooting down Russian aircraft marginally more efficient” as a very good thing (on assumption that Russian army is one more time invading someone).

The first cannot be really stopped, in the same way as they cannot be stopped from day using Linux and other open source software. So the second is (for me at least) welcome to balance the first one.

Thanks for mapping all these things!

As person who started this ATP threads: I do not see such projects as replacing manually added POIs at all.

I see it exactly as augmenting/helping. Though I think that pointing out few missing shops/offices is still helpful.

But if it would become possible to update just 3% of opening hours of POIs using this dataset and help map additional 1% of global POI coverage… Given how many POIs are there it could be equivalent of having many extremely dedicated POI updaters.

Of course it could be very different in a shopping mall full of international and national brands.

Ironically here ATP struggles with location being inaccurate and not pointing to specific plane within mall. Many brands prefer to set POI location at parking (where client is expected to arrive), not actual shop location.

Maybe it is related to 4.0.0 being not listed and 4.0.1 being listed at https://docs.osmcode.org/pyosmium/ ?

user manual link in https://github.com/osmcode/pyosmium/releases/tag/v4.0.0 is also refusing to work

https://docs.osmcode.org/pyosmium/v4.0.0/ and https://docs.osmcode.org/pyosmium/v4.0.0/cookbooks/ linked in this post are 404ing

iterative syntax looks nice! But handler functions and preprocessing are still needed if you are interested in location of objects, right?

BTW, I see that my comment is the first one - have you submitted this to OSM Weekly/created OSM forums thread/maybe posted on imports mailing list?

Not sure whether I managed to miss it in all such places or have you not posted about this tool there.

Hello! I got linked here as I started to build a sort-of similar tool (link in https://codeberg.org/matkoniecz/improving_openstreetmap_using_alltheplaces_dataset/issues/8 ).

I definitely prefer to not invent the wheel so I went here to review what exists already and hopefully use this tool or contribute to it.

Quick feedback, from opening website:

• I failed link to source code or project website at https://sdm.etica.ai/v/0.5/ and given AGPL license I expected it next to mention of AGPL
• Help text on pressing “help” is not in English while other page elements are in English
• “itens” should be “items” right? Unless it is some specialized term?
• I see some other typos/nonenglish - is it useful to report them? Where I can just submit patch to fix this?

Good luck with your project :)

Or rather, projects, including non-osm ones. And yes, it is likely better to ditch OSM and focus on school than opposite.

Maybe you got answers already but in case…

Why does Regina have so many pedways over streets cars drive under, and none of them are marked with a maximum height sign?

Are these high enough to fit a truck below it? Often there is max size for regular vehicle and if such vehicle would fit then height limit is unsigned…

Is a concrete block coloured red a form of tactile paving, even if it has no different texture to it from any other block?

no, but it may serve similar purpose and help nearly-blind people

Also, I want to express appreciating to DWG for cleaning up this undiscussed import, apparently imported from data source on incompatible license.

it is against OSM policy to delete a massive amount of legal data with out proper formalities.

which one?

note that not all legal and public data should be uploaded into OSM

also, as explained at https://community.openstreetmap.org/t/apparent-use-of-unauthorised-source-for-beach-names-in-australia/108721 it was NOT legal to mass-upload this data to OSM, at least we have no indicator that it was legal

there was never a formal proposal about the removal of this information

See osm.wiki/Import/Guidelines

It is inverse, you need a clear proposal to import data

Is Cygnus dead nowadays? I am asking as it was featured at osm.wiki/Conflation and I just removed it in osm.wiki/w/index.php?title=Conflation&diff=2717366&oldid=2597408

In case that it is available somewhere, please let me know so I can repair link rather than removing link to auctioned domain
