Was the customization to make a square projection that ran from 85
degrees south to 85 degrees north?
Thanks

Yes, you have to use Mercator. To make the tiles match perfectly across the
whole world, you will need to use a custom Mercator rather than the default one
in MapGuide (last time I did it, I had to hardcode the projection into
MapGuide). I think that if you restrict yourself to a small region, you can get
away with the Mercator that already exists in MapGuide and some tiny
translation tweaks to make it all align perfectly.

Subject: Re: [mapguide-users] Generating tiles for google maps
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.

Hi,
I'm looking for a way to generate custom tiles for google maps or Ms
Live maps / Virtual earth using Mapguide OS.
I've created my map using studio and I'm now thinking about using the
Automated tiling engine from WSD to generate the tiles.
My main problem is about which scale to use to have my custom tiles
match with google maps tiles. What are the mapguide scales I need to
use for specific google maps zoom levels?
Moreover I want to generate tiles only for a specific lat/lon
bounding
box. Is this possible using the Tiling engine?
Any help appreciated !
