I'm not sure whether removing the geological=rocks tag from this feature was correct. Can you tell whether the latest tag change was appropriate?

I'm not sure whether the latest changes to the Langertstein node are correct. Can you verify whether the changes to the tags are appropriate?

I'm not sure whether the latest changes to the Tierstein node are correct. Can you verify that the changes to the tags are appropriate?

I'm not sure if the latest tag changes to Deslizamiento Kantutani (way/687473622) are correct. Do you have any thoughts about the recent changeset?

I think the convention would be to use all lower case for tag values: osm.wiki/Any_tags_you_like#Syntactic_conventions_for_new_tags

I am not sure that the latest change of the geological=rock tag on Oberer Rodstein to material=stone is correct. Do you have any thoughts about the change?

I think the geological=landslide tag should be restored here, since the hazard=landslide tag refers to the location of signage indicating where landslides are common, and these features are not signs but the debris fields from prior landslide events.

A volcanic neck (or volcanic plug) is not a type of volcano, but a feature formed within a volcano and (in the context of OSM) exposed by erosion of the surrounding rock. I suggest we revert this to geological=volcanic_neck.

I'm going to change this back to geological=dome, since there's plenty of reason to believe this is the same type of feature as the Richat Structure.

Can we talk about the large scale change of natural=landslide to hazard=landslide? The way I understand the keys, hazard=* is for things that are an imminent danger. If a landslide is old enough that it hasn't moved significantly in a long time, it doesn't seem to present any imminent danger. That would seem to be the case for many (all?) of these features. In this case, the natural=landslide tag seems to be describing the landform created by the landslide. Were you thinking something else?

Hi,

I'm glad we can have this discussion but let's continue it in direct messages since we're already in touch there. That will give us an opportunity to have a more detailed conversation.

Thanks!

And of course, the tag for that "cliff" would need to end up in the right place after the merge.

My inclination is to presume that whoever mapped it before got it right.

It seems possible that way/157329997 and way/625187013 could be merged with the tags transferred.

Since this is a geological feature, aerial imagery might not give us a good representation of the extent of the feature. (Some parts may not be apparent in the imagery, or might be obscured e.g. by sand.)

If I were trying to merge the ways, I would try to confirm the extent of the feature from one or more reliable external sources to decide which of the two ways more correctly defines the boundary of the feature.

Thanks for adding the Wikidata ID and link to the English Wikipedia article!

It may be that the Google translation isn't so good, but I found the English version to be a much better explanation of the feature.

I noticed that the natural=cliff tagging might not be right, but figured that whoever mapped it previously might have invested some time into figuring it out. So I wasn't going make guesses from aerial imagery without being able to confirm the profile of the feature from a definitive source. Topographic maps or elevation data might be helpful here.

Hi Krako73. Thanks for getting in touch by direct message as well. Let's continue the conversation there where it's easier to have a more detailed discussion.

Although the Downie Slide is a massive landslide, it is slow moving and it has been stabilized by BC Hydro so it is no longer a hazard. (See https://cgs.ca/pdf/heritage/Rev5-CGA24-Downie_Slide-EN.pdf) Shall we restore the geological=landslide tag to identify the nature of this landform?

How were you able to verify that this dike is not magmatic?

The oilfield at the center of this feature suggests that it would be a geological dome, since the majority of the worlds oil deposits are found in geological domes. What source did you use to determine that this is a volcanic caldera rim?
