Hi<br>
<br>
Did U have some interesting URL ( WMS->GE gateways) to give us for
that.<br>
<br>
Thanks<br>

<pre wrap="">There are a couple of WMS->GE gateways. You could use one of those to load
the GE basemap as a WMS layer, then put the PostGIS data on top of it.

Subject: Re: [postgis-users] Google Earth/PostGIS integration
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.

With time a little short these days, I'll simply sketch out a few key
points--
1) The viewbox parameters for Google Earth (bbox, tilt, heading,
range, etc.) can be read by a server script (PHP, ASP, CFM, etc.) via
a Network Links layer in GE.
2) Now that you have a handle on where the viewer is looking, how far
they're zoomed in, etc., you can craft SQL queries to do perform
geoprocessing operations (e.g. clipping), etc. Again, using
server-side scripting, you can then query your PostGIS db on the back-end.
3) The Geometry specifications for Googles KML (Keyhole Markup
Language) are very similar to the OGC's GML standard. So pulling
geometry out of PostGIS using the 'AsGML(the_geom)' function gets you
90% home in terms of converting query responses back into KML.
4) Applying the appropriate MIME types to the KML you send out from
the server will ensure that the receiving browser knows to shuttle the
response to the GE interface.
5) Using GE's internal web browser (Windows only), is a handy way of
keeping the user in the general "environment" even though technically
the bulk of the data transaction is taking place between web browser and
