Duplicated tagdetect duplicated tag using mapcss

Klerik7 · 2024-05-15T14:44:38.629Z

I would like to check the key “ref:minvskaddress” using the validator, because it happens that duplicates of this key are created… could anyone help how to create such a mapcss, so that when running the validator it catches this duplication? since a similar principle works for addresses, it could work here too…it would look for a duplicated value of a given key higher up…I can’t find what code is used for duplication of addresses

Welcome, question about josm I guess.

I think this is not done via mapcss as mapcss is acting on a single object so it can not do this compare. The code should be relatively easy to find if you have the exact text of the “address error”

Klerik7:

it prints the text: Duplicate house numbers

A grep through the josm sources gives:

josm/src/org/openstreetmap/josm/data/validation/tests/Addresses.java
239:      .message(tr("Duplicate house numbers"), marktr("''{0}'' ({1}m)"), simplifiedAddress, (int) distance)
335:    .message(tr("Duplicate house numbers"), marktr("House number ''{0}'' duplicated"), entry.getKey())

See Addresses.java in josm/trunk/src/org/openstreetmap/josm/data/validation/tests – JOSM

An alternative is to use Overpass:

Return entities with duplicate names

question

Hi I want to select all `railway=stations` & return any which have the same nam…e. I've used [This wiki example](https://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_API_by_Example#Find_relations_with_identical_wikidata_tags_.28since_0.7.54.29) as a starting point. This is as far as I got: ``` [bbox:{{bbox}}]; nwr[railway=station][name]->.a; foreach .a -> .b ( nwr.a(if:t["name"] == b.u(t["name"]))->.d; ); .d out center; ``` It appears to only return the last found duplicates, so I added a line to try & collect them together: ``` [bbox:{{bbox}}]; nwr[railway=station][name]->.a; foreach .a -> .b ( nwr.a(if:t["name"] == b.u(t["name"]))->.d; (.d ; .result; ) -> .result; ); .result out center; ``` But it returns all stations in the bbox. This [Overpass Example](http://overpass-turbo.eu/s/Acc) would hopefully return New Cross Gate station as well as Greenwich. ---- From the [Union/Set wiki page](https://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_QL#Aggregators) its unclear to me what `u` returns if there are multiple values found.

yes, the question is about josm…

when the address is duplicated, it prints the text: Duplicate house numbers

this test should be performed by this item
