You can share a public or unlisted map for viewing in Google Earth. The table needs to be downloadable.
What is exported to KML?
- Map styles and info windows.
- Geocoding done within Fusion Tables is not exported. Google Earth will initiate geocoding of location descriptions while viewing a KML file.
- Placemarks are labeled using "name" column, or failing that, the left-most text column.
Static KML
Download a static copy of the map for viewing in Google Earth. Open the downloaded file in Google Earth, email the file to your friends, or upload it to your website to share.
- While looking at the map, choose File > Download.
- Select KML.
- If a filter is currently applied to the map, choose whether to apply it for the KML download.
- Click Download.
Subsequent changes to the Fusion Table won't appear in this static copy of the data.
Dynamic KML link
A dynamic link from Google Earth to your Fusion Table means that any changes to your data online are reflected when viewed in Google Earth.
- From the map tab, choose File > Download.
- Select KML Network Link.
- If a filter is currently applied to the map, choose whether to apply it for the KML download.
- Click Download.
- You receive a small KML file that you can open in Google Earth to view the map.
