This is still the case. The lower zoom, the worse. That is why I turned of lowzoom captions on z0-6 again. Continent captions, country captions were far (extremely far) out of place. I think the place where Oslo is located was labeled "Italy" :-). Fixing this to use proper projection and have labels be displayed correctly would be awsome. Basically, it would use the correct "Project" functions in 2-3 places in orp (as the patch you forwarded me once did), right? bobkare was interested to do the same in XSLT (apparently they have cos/sin emulation now), which would make us use proper projection which would be good anyway. Frederik, do you think you (or somebody else) could have a go at that? I'd love to being able to reintroduce labels in lowzoom. > Also, the same user reported some white squares on zoom levels 11 and > smaller, which seem to be lowzoom artifacts.

No, they are autogenerated, and there is no way to request a lowzoom rendering. I have seen the while squares (empty land) too in current stable [EMAIL PROTECTED] clients. 2 1/2 reasons: - There is a bug (that I won't be able to look into) that makes "captionless" create one empty land tile, even if the OSM file contains loads of stuff. This is even with stable [EMAIL PROTECTED] clients. I have not looked deeply into this. Someone should examine this. I tried e.g. ./tilesGen.pl --Debug=1 --Layers=captionless xy 2208 1376 - I am deleting old legacy tiles and for areas where no new captionless has been produced yet, it will be replaced by whatever oceantiles.dat tells us (empty land usually) - There is also one bug on the server side (in addition) that somehow seems to create an "unknown" lowzoom tile if underlying captionless tiles are not existing. It should fall back to oceantiles.dat information in these cases and I will look into that next week.
