see also here:

as far as i understand the ogc-kml-manual
(http://www.opengeospatial.org/standards/kml , =>  2.2.0 	OGC KML), the
Latitude-Longitude are in EPSG:4326, but measuring the height/elevation in
google earth is in EGM96 vertical datum and not in EPSG:4326.

in my experience overlaying kml (vector and raster) with EPSG:4326 in google
earth works relatively well in flat areas, in mountain areas there are
sometime distortions therefore.
