Hi all,
Can anyone explain why my styles change when I zoom in in Google Earth
when making a KML request to geoserver. I am loading a outlined only
polygon, everything looks fine until I zoom in to a high scale then by
line thickness drops to one pixel and a point/icon is added to the
center of all the polygons

So I think what's happening is that it's switching between raster and vector representations. The KMScore parameter controls when this changes. If you pass in the param kmscore=0 then you should always get the raster representation.
There are some advantages to the vector representation, the point/icon allows us to display more information about your data, and you can customize the output with a template. I think you can also keep the description information but turn off the point actually appearing with kmattr=false
One thing that concerns me is that the line thickness is only one pixel. What should it be? What's the value in your sld? Google Earth tends to draw lines a bit more thinly, but if yours should be very thick and it drops to one pixel then that's a problem.
best regards,
Chris

Chris,
Thanks for your response. I have included my style and a couple
images illustrating the change in line width.

That does look pretty thin for a 3 pixel stroke width.
Huh, looking at the KML specification it looks like they give you no way to control the thickness of the line in a polygon. They do for linestyle, but not for polygon style. So I guess I'd say this is more a bug with Google Earth?
So if you want it to look the same all the way down you should just set the KMScore to 0, and have GeoServer do all the rendering.

Actually, thinking on it, it may be possible that adding a LineStyle to the KML Style output will make it properly render, as I could see them having that sort of logic in google earth.
Travis, could you possible take some KML output and add in a LineStyle, in addition to the PointStyle and PolyStyle that we set for polygon output, set the width to something large, and see if google earth renders it different?
If so then we will know that it'll work, and then put an issue in to our task tracker - http://jira.codehaus.org/browse/GEOS and we'll get it fixed for you.

Chris,
I have taken a look at the kml output it looks as though google requires the
polystyle fill defined to have the outlines rendered at the correct width.
<PolyStyle>
<color>00aaaaaa</color>
<fill>0</fill>
</PolyStyle>

? I don't think I understand what you're saying? Are you saying there's a way for us to set the width for a polystyle? Or that it's not possible?

Hi Travis,
One more suggestion that might work..
Unless you need the attributes, (those very big point looking things)
you can opt to turn them off entirely by appending &KMATTR=false to
your Geoserver KML request. This will give you vectors without the big
attribute blobs, that for the moment cannot be styled by Geoserver as
far as I can tell.
See
http://docs.codehaus.org/display/GEOSDOC/KML+KMZ+Output
for more details as well.
Best regards,
Jason

Which can not be styled? The black circle things can be styled with SLD. If you change the color it'll pick that up. And if you use an external graphic it will use that image instead of the black blob. It can point to any image, local to geoserver or remote on the web.
And the description attributes can be styled with the description template.
