Talk:Mercator

Is there any reason we're showing the ellipsoidal mercator projection here instead of the (much shorter) spherical one? --GabrielEbner 14:50, 9 October 2007 (BST)

The online Lat/Lon to Mercator converter give different results than the C and PHP codesamples (and maby the others to)

Can anyone check witch results are the most correct?

In playing with building my own rendering engine from Mercator-stored coordinates in our OSM database, I found that the data was stored using the spherical projection rather than the ellipsoidal projection. I've commented on it and included a Java class at my blog; didn't want to start hacking away here until someone verified my own musings. :-) --W3woody 22:54, 29 July 2011 (BST)

Code licensing

I'm working on a library that is operating on OSM data. I'd like to reuse (copy) code found on this page. Looking at the license text on bottom of the page, it seems all content of the page (including code) is licensed under CC-BY-SA. Unfortunately I figured that GPL is incompatible with CC-SA-BY 2.0.

Is it possible to get the original authors of these example code to relicense their work under a different license that is compatible with GPL?
