[Qgis-user] How can I exporting KML for Google Maps

[Alex Mandel]

Have you considered making a simple OpenLayers webpage with Google Maps
as the basemap you can easily overlay the kml on top of it.

It's unlikely that anything is wrong with your kml and you're just
hitting limitations of the Google web tools.

Enjoy,
Alex
