Well, just because you cannot see the crater on aerial imagery (because it is so big and is covered with forest, it does not mean it does not exist. You need to check height maps or hill shading layers to see the crater nicely, check e.g. your own link of node/26864346#map=12/48.6606/19.4709&layers=P.
The peak at node/26864346 is just the highest peak of the creater rim and it is called the same as the old volcano. IT is marked natural=peak so it can be clearly distingushed what is the volcano and what are some peaks on it. Notice there is also another one at node/5657428552 .

I agree with what you say, I just do not agree with the assumption that there is nothing of the volcano on the ground.
There are only a few old volcanos mapped in Slovakia, those that still look like craters or there are volcanic materials to be found on the slopes of it.
Like https://www.freemap.sk/#map=15/48.378331/18.639979&layers=X&osm-node=12404740519 .

We have not mapped https://sk.wikipedia.org/wiki/%C5%A0tiavnick%C3%BD_stratovulk%C3%A1n , which we could if we mapped geological history as you falsely accuse us. All your other examples are just extreme extrapolations that nobody mapped.

Hi, it does not matter that Bing or Mapbox are commonly available. But they may provide imagery from different dates and different level of quality so it is useful to know which one you used. Also many countries have their own local imagery, so it is useful to know that you did not use those.

Sorry, I do not know what AMDB is and I also don't understand what 'airport diagram' actually means. Also you have 3 changesets with same description on the same airport, so maybe some disambiguation would be useful about what was done on each one (like why there are 3). Also airport name would be useful for cases you want to return to the changeset and you only have a list of them. Or some other people that watch regions and see just the descriptions can ignore places they do not care about. If you do not write what airport you changed, they need to go a go and look closely.

Yes, some tools can highlight visually what was changed. If it is understandable why you changed it, a short description is OK. But there are cases where an explanation WHY you changed something is needed on the changeset.

Dakujem.

Thanks!

Yes, there is an extinct volcano in the middle of Slovakia (and not the only one). It's crater is at way/1379027424 . It is no mud geyser. Maybe the node is missing some website or wikipedia link to show the volcano is real, just extinct. But the remnants shape the whole region here.

The elevation was given precisely, it represents the whole volcano, not just the elevation at the position of the node. Check other major volcanos in the world (Vesuvius, Fuji, Mt. Rainier), how they are done.
It is also written on the node in the 'note' tag, thus for other mappers like you. If you do not understand (and don't bother to copy it into a translator), you are not allowed to touch objects/tags you do not understand.

If you just wanted to fix (wrongly) the suspected wrong elevation you could just delete the 'ele' tag. There was absolutely no reason to delete the whole volcano.

10 changesets with the same dubious description of "airport diagram" seem weird, please use proper changeset descriptions (see osm.wiki/Good_changeset_comments ).
Also quote the sources of your changes on the changeset (you provide none on changeset and none on the objects you add). See source=* .

What did you fix here? You just removed the correct node that represented the whole volcano, which you now have completely destroyed.
Of course, the 'ele' tag did not represent the elevation at the node location, but that seems to be correct method for volcanos. It was also written on the node, if you cared to read.

Hi, what does cuisine=community_centre mean on these cafes you add? That does not seem like a type of cusine (what food is served).

No dobre, ale ste ho zakreslili ako funkcny obchod. Opravim teda.

The shop states it is closed since Jan 23 2026. So how could the opening hours be valid at 2026-04-06 when you surveyed it?

Zdravim, ten LIDL vo februari fungoval? Lebo dnes je cely v rekonstrukcii.

Ja len, ze ked uz ste tie adresy vytahovali z registra adries, tak tam boli aj tie identifikatory a dali sa porovnat. Ale ano, asi by to bolo pracnejsie.
OK, prave ich doplnam.

Ano do fora som napisal niekolko otazok, zatial bez Vasej odpovede.

Ok, ak ste pouzili tu mapku mesta a vedeli ste tie hranice podla nej zakreslit tak mozno OK. Aj ked neviem aky je rozdiel v hraniciach, ktore som urobil ja na admin_level=11 a 12 a tymi Vasimi na level=10. A preco tie vase maju place=quarter a border_type=quarter to neviem, to urcite nesedi na to co sme diskutovali doteraz. Ako som pisal na fore, zaktualizujte cely Vas navrh preznacenia, aby sme videli, ci to do seba zapada.

Katastralne uzemia sa mi javia kompletne vsetky. Pri Martine je nieco navyse,alebo prekryv. Pozriem na to.

No Vasa lokalna znalost je teda obdivuhodna. Bolo by vhodne linkovat na konkretne VZN obci alebo zdroje, ak chcete pridavat taketo neoficialne nazvy ulic ci objektov. Nech aspon je jasne, ci to uz nie je zo storocnych map ako doteraz.

Zdravim, preco vymazavate na adresach znacku ref:minvskaddress? Zda sa, ze Vase zmeny adries su spravne (asi mesto precislovalo niektore adresy), ale identifikator adresy im zostal rovnaky.

Ano, este je to vacsinou zarastene. Neviem presne kde sa uz stavia, nie su fotky.

I have "fixed" the Flixbus routes in Bratislava, so that those that targeted the old central bus station now stop in the new one (AS Nivy). It was a mechanical fix as I do not have a source to check if the particular bus line still stops there or is in any way valid. Some are also tagged to stop at Most SNP in Bratislava, which is unclear if really both stops are served. Yes, the line connecting just Bratislava and Vienna may do so, but not the more long haul ones. If you can check it better please do so. Thanks.

Pretoze to tam tak bolo :)
Nie, lebo na wikidata zatial neexistuje Penta Bank, tak uvidim ci to niekto zmeni na existujucom wikidata id alebo bude nove.
Tak zatial som to nechal tak. Ak to navrhujete dat prec, tiez je to moznost, nie som proti.

Pardon, toto som zle pochopil. Zmena je spravna, na removed:building=yes. area=yes bolo zbytocne, ale to uz ste vyriesili. Dakujem.

Ona uz bola oznacena ako zburana pred Vasou zmenou, ale kedze moze byt viditelna na starsich fotkach este nejaky cas, robi sa to takto, ze sa objekt ponecha a zmeni na removed:building=* .

Takze tato Vasa zmena nie je prinosom.
