I had a similar problem. <br>
<br>
It seems that by default; the parameters for the transformation from
the bessel ellipsoid to WGS84 ellipsoid are not set correctly within
the epsg definitions. I solved this by altering the definition for my
projection in the EPSG definition file on my server.<br>
<br>
So you should determine if the projection you use (31300) has a
ellipsoid definition other than WGS84 and then look to find what
settings you have to use for "towgs84="<br>

<div bgcolor="#ffffff" text="#000000">For wms layers to show up in
Google Earth, you generate a
groundoverlay. The projection of the mapfile or layers itself is not so
important, as long as the wms service is able to publis in epsg:4326. <br>
<br>
This means that in your map metadata you need to have something like:<br>
<br>
METADATA<br>
"wms_title" "My WMS map"<br>
"wms_srs" "EPSG:4326 EPSG:28992"<br>
"wms_onlineresource"

target="_blank">"http://www.myserver.com/cgi-bin/mapserv.exe?map=somemap.map"</a><br>
END<br>
<br>
where you separate the supported projections with spaces.<br>
<br>
<br>
When you create a GroundOverlay, Google generates the following kml
snippet:<br>
<br>
Make sure to add the STYLES= to the end of the request or mapserver
will generate a wrong result (this is for my 5.0 installation)<br>

It is also possible to show a mapserver legend in Google Earth with the
following kml snippet:<br>
<br>
<ScreenOverlay><br>

yunits="fraction"/><br>
<size x="-1" y="-1" xunits="pixels" yunits="pixels"/><br>
</ScreenOverlay><br>
<br>
<br>
If you embed these snippets in a kml file, you can see what happens.<br>
