[Tilecache] Seeding map images

[Evandro Dugnani]

Hi Christopher,

  Thanks for your reply.
  I was adjusting some things here that were not fine.
  I´ve discovered that I had to change configuration on Tilecache,
Geoserver and Postgris. Now I'm generating images for EPSG:41001, but
anything is not OK yet. My target is generating tiles equal to Google
tiles. But my tiles are dislocated according Google's tiles. For
example, take a look at these two imagems:
  - From Google Maps: http://mt0.google.com/mt?n=404&v=w2.61&x=760&y=1164&zoom=6
  - Generated in my system:
http://www.esnips.com/doc/4e35d788-112b-4517-b936-7526f865d122/760

  Notice that images are vertically dislocated each other.

  Do you know what I have to do in my configurations to correct that?

  Thanks in advance.
  Regards,

Evandro
