Web Mercator overlays broken with "maxResolution: 156543.0339"

Reported by: nrenner Owned by:

Component: Layer.XYZ Version: SVN

Maps with option "maxResolution: 156543.0339" calculate wrong tile URLs for overlays, at least when using Google as base layer and OSM as overlay, see:


This probably has been introduced by  #219.

Simply not setting maxResolution or setting "maxResolution: 156543.03390625" does work, but many existing maps probably still use "maxResolution: 156543.0339" and might get broken.

Thanks for reporting this mrenner.

Andreas, I'm not yet familiar with the new code. Do you think that's a regression?

Changed 3 years ago by ahocevar

@erilem: not a regression. We have this behavior since r11118 (i.e. pre 2.11), and 156543.0339 was an incorrect maxResolution.

Hmm the same example works for me with 2.11.

Changed 3 years ago by erilem

It probably works with 2.11 because the layer has a maxResolution so that of the map has no effect at all.

If we don't want to fix that because users should use correct values then we may want to add something in the 2.12 release notes.
