Why would someone destroy the name of the peak?

KiaaTiX, why would you destroy the Zonnepark information with your edit??

PS: the DEM is the Copernicus GLO-30 one.

TXs for coming back re. this "peak".
I am preparing a new release of the OAM world maps and - after 6 years from the initial peak selection and rendering - revisit this topic. While in the Urals, Pamir, etc. etc. you have dramatic peaks, there is nothing like that in huge areas of Russia and Canada. But still, there are "high points" that may be just a few m above the average of 200km around.
And most of them are not named, as they are lacking "drama". The only way to identify candidates is to use a DEM and an algorithm that screens for high points and calculates their isolations.
If you have a real elevation in your area that is higher than this place, pls. take over and put that one in (or move and correct name and elevation of this one).
TXs and cheers

Sorry, a mistake of mine, will revert the change.
Background: after 5 years I'm re-building the rendering of peaks depending on their isolations for the world maps at openandromaps.org. Back then I was shocked to find the highest peak at the Philippines, at 28,000+ and tons of elevations in feet that were put into the metric field ele in OSM. You can imagine the disaster. I fixed a 4 digit number of peaks back then to get the highest isolations about right.
For the new sweep I still found tons and tons of mismapped peaks. So I built a list of peaks with relevant isolations and calculated the quotient between OSM and DEM ele. If that number is about 3.3, then you can bet this is feet in the meter field. UNLESS you are dealing with a peak very near to the coast, which is in particular true for small island peaks like here. While I was spending hours and hours working through the suspect list, concentration slipped away and I did not recognize the island nature of the area.

You're welcome.

Next try :-)
"ele wrong by a factor of about 3, which hints at feet figures put into the OSM elevation field that requires meter values. Feet figures obviously create havoc in the OSM data."
Thank you also for the additional link; interesting discussion, but not a magic wand either. I've made a comment in that thread, too.
Cheers

Hello Will,
I will not disregard, and I hear you.
So, for future edits I will adapt the wording.
What do you think about this: "ele wrong by a factor of about 3, which hints at feet figures put into the OSM elevation meter field that requires meter values. Feet figures obviously create havoc and pollute the OSM data."
This avoids the term "vandalism" but clearly states the severity of the issue, I think. Your thoughts?
My edits have not been triggered by the post in the link you quoted. But my use case suffers similarly: I am the guy building the world maps for openandromaps.org. And for increasing zoom levels I highlight more and more peaks based on their isolation. You can imagine what happens when you have a mix of meters and feet elevations in a region ...
A hill of 300m mapped as 900 something will blank out a real mountain of 800m. e.g. invalidating my map highlighting.
I would agree that most people who input feet figures do that ignorant of the consequences. (Although it's not SO hard to know that most of the world uses metric measures and to imagine that a transparent mix of both leads to pollution of the database. But let's assume they are just focused on feeding more into OSM, which is good per se; hence vandalism is not an appropriate term for those authors. I bet, though, that there are folks who know well, but feel "imperial" enough to give a sh.. about it. For those my term is even to friendly. But from looking at a peak node we cannot tell about the attitude of the respective author ...
Hence my agreement to adapt the wording for future comments. Can you pls. advise re. my proposal above?
TXs and cheers
Michael

Spot on, thank you, watmildon.
I stumbled into this bank item when rebuilding the dataset for settlements, in preparation for re-rendering them for the openandromaps.org world maps.
TXs for the quick response and resolution.
Cheers
Michael

This normalization ended up with a bank that has a population of nearly 7000?

Hi, I am generating world overview maps for OpenAndroMaps that also include significant peaks (high isolation and prominance). For such I am analyzing ALL peaks in OSM by calculating the ration between ele in OSM and SRTM. And for the most brutal anomalies I have a "manual" look, and correct if needed, to avoid crap in my maps as good as possible. When this journey started, I found elevations of 28000 - some dummy had put a feet value into OSM (m is WW standard) without notice, and there are 1000s of such ... In the particular panama case you can have a look yourselves: the nearest contour line shows 950m.
Cheers

osm.wiki/Key:admin_level
Zitat daraus: Usage
The admin_level=* values are also used for the capital=* and heritage=* tags. Besides administrative boundaries, the admin_level=* tag currently has very few usage on features tagged with government=*.
Dein Capital "county" ist ja korrekt. Und nett, aber nur innerhalb Schwedens.

Ich habe im Wiki die Definitionen nachgelesen. Außer, dass JOSM das tötet, ohne Begündung, ohne Hinweis auf Ersatz, habe ich nichts gefunden.
Das "Rationale" ist immer noch gegeben. Und Nominatim mag ein Ersatz sein für gewisse OSM Webseiten Services, aber löst meine Aufgabenstellung nicht.

For this country, province is clear, I know.
Happy to substitute "municipality" by something more meaningful. What is the right "place" type then, pls ?
But should not "capital" be removed, too ?
And put to Saratamata?

Well, the OSM database speaks differently. And in my work, I deal with nearly 200 countries ...

Wikipedia is not very clear here. So, if somebody with local knowledge can take care this is very appreciated.
My interest are local province capitals. Being well aware, that "province" means different things in different places; sometimes simply use another term for it.

69007567 over 6 years ago

Frederik, s there a proper query in your paradigm that gives all province capitals?
I am dealing with world maps, and the chaos you spot on the way is incredible. "Islands" of "traditions", incomaptible, intransparent. And the worst of all were peaks with elevations in feet - without notice. 4 digit of them.
Maybe you have a proposal ?

69010434 over 6 years ago

You are SO right ! TXs a lot.

60610220 about 7 years ago

This is a province capital, hence it makes sense to know the associated country. Maybe useless for you personally, not useless for others.
