[postgis-users] Google Earth/PostGIS integration

[Ezequias Rodrigues da Rocha]

Sure it is nice. I just thought it could be more easy do a postgis 
connection with Google Maps. But  how to connect (or just see) this bases ?

I have a desktopGIS with me and would like how to load a layer on Google.

Ezequias
