[mapserver-users] Strategies for creating Google Map tiles...

[Roger André]

Hi John,

I've had good success with Option 1, but I'm not sure I understand all of
the conditions you've mentioned.  I assume that you intend to display these
tiles in a Google Maps mashup when you're done?  If so, using  TileCache's
tilecache_seed.py would allow you to pre-generate the tiles using Mapserver
initially, and then display them in the map - without ever calling on
Mapserver again.  The major advantage I see to this method is that Mapserver
can aggregate all of the separate layers and display them in a common
projection.

Good luck,

Roger
