importing kml with gx:track to fusion tables

I'm trying to upload a kml file created by gpslogger to google fusion tables, but the data will not import.

The data is structured using the gx:track element and looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2" xmlns:gx="http://www.google.com/kml/ext/2.2" xmlns:kml="http://www.opengis.net/kml/2.2" xmlns:atom="http://www.w3.org/2005/Atom">
<Document><name>2012-07-25T00:43:29Z</name>
<Placemark>
<gx:Track>

<when>2012-07-25T00:43:29Z</when>
<gx:coord>-42.41141004 18.05962572 18.700000762939453</gx:coord>

<when>2012-07-25T00:45:50Z</when>
<gx:coord>-42.41167598 18.0596267 -3.100000381469727</gx:coord>

...

</gx:Track>
</Placemark></Document></kml>

When I try to upload it I get 3 empty columns: desription, name, and geometry.

So what's the problem?

I'm not familiar with any these tools, so hopefully I'm not making a dumb mistake.

Solution

FusionTables KML support does not include the gx: namespace. To import that into FusionTables you will need to convert it to "normal" KML.
