[GIS] Can a Fusion Tables Heatmap be used in Google Earth

google earthgoogle-fusion-tablesheat map

From the Fusion Tables web interface there's an option to view a heatmap, which draws on top of Google Maps.

From the Fusion Tables map view there's an option to Export To KML, which allows the Fusion Table points to be displayed in Google Earth.

Is there a way to add the heatmap to Google Earth?

Thanks

The official answer from Google's Fusion Tables team is that this is not currently possible. I've added an enhancement request for this.

[GIS] How to toggle Fusion Tables layer on/off based on map scale

This seems to work - it doesn't seem to be a problem to call setMap if it's already set:

google.maps.event.addListener(map, 'zoom_changed', function() {
    zoomLevel = map.getZoom();
    if (zoomLevel >= minZoomLevel) {
        FTlayer.setMap(map);
    } else {
        FTlayer.setMap(null);
    }
});

Thanks to Chris Broadfoot from the GM team for this tip.

[GIS] Set ZIndex for Google Fusion Tables in Google Maps API

I don't see a method for doing this in the Google Maps API v3 reference, and that lack appears to be confirmed by this comment from a Google employee:

https://groups.google.com/d/msg/google-maps-js-api-v3/ovT1ekQ-HGQ/k-b8BSxCCjAJ

FusionTablesLayer (and KmlLayer & co) don't have the ability to re-order based on z-index.

There is an active feature request for adding sorting by Z-Index for KML layers here: http://code.google.com/p/gmaps-api-issues/issues/detail?id=2804

I am not aware of a corresponding feature request for FusionTableLayer objects, although perhaps the solving of one would facilitate the solving of the other.
