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"
<a class="moz-txt-link-rfc2396E" href="http://www.myserver.com/cgi-bin/mapserv.exe?map=somemap.map">"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>
<br>
<GroundOverlay><br>

<south>52.19180808173348</south><br>

<west>4.652306951338773</west><br>
</LatLonBox><br>
</GroundOverlay><br>
<br>
<br>
<br>
It is also possible to show a mapserver legend in Google Earth with the
following kml snippet:<br>
<br>
<ScreenOverlay><br>
<visibility>1</visibility><br>
<name>Legenda - Percelen</name><br>
<Icon><br>
<href><a class="moz-txt-link-freetext" href="http://www.myserver.com/cgi-bin/mapserv.exe?map=somemap.map&VERSION=1.1.1&REQUEST=GetLegendGraphic&LAYER=aLayer&Format=image/png">http://www.myserver.com/cgi-bin/mapserv.exe?map=somemap.map&amp;VERSION=1.1.1&amp;REQUEST=GetLegendGraphic&amp;LAYER=aLayer&amp;Format=image/png</a></href><br>
</Icon><br>
<overlayXY x="0" y="1" xunits="fraction"
yunits="fraction"/><br>
<screenXY x="0" y="1" xunits="fraction"
yunits="fraction"/><br>
<rotationXY x="0.5" y="0.5" xunits="fraction"
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>
