[mapserver-users] Google tile schema to coordinates conversion

[Armin Burger]

Hi all

I would like to set up a scripting solution based on MapScript that 
replies correctly to requests using the Google tile schema x+y+z. Does 
anybody know a formula how to transform the XYZ request values to 
bounding box coordinates in the Google Spherical Mercator projection?

I know that Mapserver CGI offers the tile mode for this. It works very 
well, but I would need a Mapscript solution for more flexibility of the 
request handling.

Any hint appreciated
