[mapguide-users] Generating tiles for google maps

[George McLean]

I was thinking you could create a layer that was your bounding box and 
then add your map to a weblayout. Open the web layout in a browser and 
as you zoom in to the corners of your bounding box the tiles will get 
created under the TileCache directory (at least in windows). There may 
be a better way to do this but that is how I have created tiles for 
regions within a larger map.

Thanks for the Chris Savage link. I read it a few weeks ago but now that 
I have been working on this it was helpful to re-read.
