City display problem

Posted by niski on 21 October 2019 in Polish (Polski)

Hello, i am posting here because i have strange problems with my city name displaying after 30km away (when the cities become points).

To be exact, i put a city mark properly, but it won't show up past the 30km range. I did it 3 weeks ago and rest of the map on the current zoom updated so it's not zoom updates. I tried many things, such as adding capital=4 tag (because this'd be the "capital/largest city" of my state i'm mapping in), making a new city tag, W A I T I N G, removing/adding population mark in my city name, and nothing. Later, i added some planned cities that are 0% complete and are just placeholders, when i suddenly see one of them is displaying from even 100km away! What is this problem caused by, and how to fix it, if i can ask? Also, i recently noticed the city stopped appearing from 30km and only appears to 20km zooms.

If anyone needs the location, it's here: (don't mind my poor mapping or the fact that the city is like 1% done, i just recently got this territory).

@niski - I think I found the problem with the name of your city.

The name of its city is covered more than 30 km. by that of a city called Fort Vinlex (which, due to having a longer name, occupies the space of its city's name). Another possible cause is that the name of the state appears more than 30km very close to its city.

One possible solution would be to move the name of the city (or the next one). If you find another solution, you can apply it too.

This is mainly a rendering problem.

Well, the second city has been made much later, but yea i noticed that it stopped appearing even more since i added it, so possibly the problem is the state name. Didn't really realize it, but i really want to keep my city where it is, especially since i already mapped lakes and rivers, i guess i'm just gonna make the fort vinlex a town, and keep okeravi like this. Thanks for support.

Rendering in OSM is rather chaotic thing. Of course there is a script which provides the rendering order but it is too complicated to be helpful from a mapper perspective. Also sometimes really strange things happen. For example here appears the name of Lake Lezerne which is few hundred kilometers away.

The thing is, that, if you make an administrative division, the name of the administrative division will appear in the 'absolute' center. You can see the 'problem' occurring in places where the capital is located in the center, thus, being interfered with by the country's name. Examples include Bruxelles/Brussels, Belgium, where 'Brussels' doesn't appear until layer 9, Thimphu, Bhutan, where 'ཐིམ་ཕུ (Thimphu)' doesn't appear until layer 7.

Amazingly, Singapore, Singapore somehow 'broke' this pattern, appearing at an incredible layer 4.

It's the same with Sierra (FSA), though the capital appears at on level 8, disappears on level 7

The same with Gobras City, Gobrassanya, which doesn't appear at level 6.

Singapore has at least three tags, one of which is the country itself and another the "capital" (which I believe shouldn't be there).
