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

[Aaron Kreider]

I'm working on exporting US counties into a kml file so that I can use 
it on Google Maps (ver 2).

Google Maps has a limit of 10mb for kml files.

I get a shapefile from the US Census Bureau (100mb).  I use the 
"simplify geometries" feature to get it down to under 10mb.  Then I 
"save as" kml.

Now I've got a kml that looks fine in Google Earth, QuantumGIS (1.5), 
and ArcGis.  However it doesn't display in Google Maps (I see nothing 
and there are no errors).   What is my problem?


You can see my kml: http://www.energyjustice.net/map/kml/counties01.kml

Here is my sample kml format:
?xml version="1.0" encoding="utf-8" ?>
<kml xmlns="http://www.opengis.net/kml/2.2 
<http://www.google.com/url?sa=D&q=http://www.opengis.net/kml/2.2&usg=AFQjCNEwHFB9hZtWgJkNVAn37y41v7YyFA>">
