Some buildings I mapped with the building:part tags are redered weirdly on the Positron map style. As this appears to me to be a common map style, I assume that I missed something during my edits.
You can find examaples here:
It is for example about the katholic church and the corresponding kindergarten-building:
or the town hall
which i find especially impractical as the town uses this map style for the official map on their website, and the map focuses on the town hall when opening.
Could I please get feedback whether this rendering is due to my wrong mapping? And if yes, why?
I had a look at this in my local area, and indeed I can see that Positron (at least in the version available as a background in uMap) seems to render building:part unpredictably, with some building parts appearing as transparent. I couldn’t find any pattern to this - some complex buildings display just fine while simpler buildings have rendering issues.
The only hint of a pattern I could see is that the “transparent” parts have same number of levels as the main building, so that only lower parts of the building get rendered. But that could be just the examples I checked. I can’t think of any reason to render in this way.
The Malaga ferry terminal building, for example, mostly has 3 levels - and that part is transparent. Only a couple of small lower parts are filled in.
I checked that all the “problem” buildings display as expected in the 3D rendering on CoMaps on my phone.
So I don’t think this is due to your wrong mapping - or at least if it is, it’s a problem shared by other mappers with no connection to you. It seems more likely to be an issue with Positron.
