[mapguide-users] Generating tiles for google maps

[azpublic]

Yes it is a mercator projection and it’s the one I've been using for my map.


Here is a good post about the subject.

What do you mean by "I would create the box and 
then zoom to the corners" ?

I have been trying to get this working as well. My approach has been to 
use data between 85 degrees north and 85 degrees south in a Mercator 
projection since this is what I believe Google maps uses. I am still not 
sure if this is the right approach as I am still working on it.

To get the tiles within your bounding box, I would create the box and 
then zoom to the corners. The tiles for that region will be created and 
this will help you figure out the rows and columns for each corner at 
each zoom level. Once you know the zoom levels and row/column boundaries 
you can specify these parameters in the call to the tiling engine.
