Ah, now I remember. I was following what seemed to be local convention:

node
["vending"="excrement_bags"]["amenity"!~"."]
({{bbox}});

But I'd be happy to mechanically retag all of those to include the "amenity=vending_machine".

Fixing. Both nodes had the problem.

For rendering support see https://github.com/gravitystorm/openstreetmap-carto/pull/1466

Thanks for mapping. There is a typo in "sanitary_dump_satatio:gravityn".

Cool. You did fine with the tagging: there were at least a dozen distinct tags in use for that feature. Though next time you could add a "note" tag to make things clear, in the case where the meaning of the tag is not well established.

The features are there in your original location, but do not render on the map. You can still edit them however.

Rendering support does not exist: the feature is not considered important enough to render yet, with less than 1000 uses worldwide:

Is osm.org/node/2145505013 a toilet holding tank dump spot (e.g. amenity=sanitary_dump_station )?

Updated dump station tagging. Thanks for mapping. Do both of these still exist as mapped?

In the USA "gravity" accepts blackwater with chemicals and grey water both:

Danke.

In the UK those are called "Elsan points".

I did not know there was a difference in Germany.

In the USA, Mexico, Canada the only difference is the shape and size of the hole.

How are chemical and no-chemical tagged in Germany?

What tag would you recommend for osm.wiki/Tag:amenity%3Dsanitary_dump_station ?

--------------------------------------------

In the USA a cassette is not welcome at a toilet for a human user.

The "gravity" style dump also takes chemical toilet waste. The concern is that "chemical_toilet" may be confused with a toilet for a human, rather than a place to dump contents of a holding tank.

Note that "cluster" is now deprecated for trees (it never really had a function) osm.wiki/Key:denotation

Is osm.org/node/1460386477/history a cluster or a natural monument? Could you check the denotation tag?

Considering retagging recycling:excrement to waterway=pump_out. Comments?

What is an amenity=p ?

Could we use sanitary_dump_station:cassette=yes and sanitary_dump_station:gravity=no then. But mostly get it documented on osm.wiki/Tag:amenity%3Dsanitary_dump_station talk page.

Could we discuss sanitary_dump_station:chemical_toilet before it's used too much. What does it mean?

Correcting spelling on osm.org/node/3396622871

Updated your dump station tagging
