I have seen example here how to use map.fitBounds on fusiontablelayer here and here , but I think it works with markers table only. Its impossible to parse the lat and long when the vertex coordinates are in the geometry column as in a kml polygon layer.

Is there a solution to use fitBounds or other function to zoom to the extent of a kml polygon fusion table layer?

  • I'd recommend moving this over to stackoverflow.

  • @Mapperz: its not an answer to my question... kmllayer is not fusiontablelayer

  • You can Centre the fusiontablelayer - stackoverflow.com/questions/8434685/…

  • As I said, this method works only with markers fusiontablelayer. Not KML polygon loaded in fusiontablelayer...

Yes. You are correct. Currently the functionality to zoom/fit bounds does not exist for polygon or line data from fusion tables. You will need to use the GVIZ (Google Visualization API) and the geoxml3 parser. I used some of the code from the following applications. One is a polygon example and the other is a line/arc example.

There is a post in the Google Fusion Tables group pointing out that the functionality is not there (yet). I had the same problem and I managed to get my application working recycling some of the code from the examples above. Hope it helps.

Update: Google Fusion Tables is being turned down in December 2019.


Consider moving to GeoJSON for markers/lines and TopoJSON for complex polygons.

  • Thank you for your answer, it works for me. However, have you found a way to have the extent of all rows/features of the kml and not only one at a time in order to have the bounds of the entire table?

  • @DemarsM. Fusion Tables uses the ST_INTERSECTS to find map features within a defined area. This may work. I have not tested it myself. I need to do the same for some of my queries so I will give this a try soon. I thought it was deprecated but apparently it is not. Failing that I would think that creating a KML that is a 'box' containing your area and adding to the table may work for your selection(s). Another possibility is parsing the rows necessary to capture the entire area. These are just guesses/suggestions at this point.

  • I dont know about ST_INTERSECTS. If you can do something interresting with that let me know. However, take a look a the second example, the one with line/arc. It shows how to zoom on the entire kml using union(). It works with polygon kml too.

  • Thanks for pointing that out. I totally missed that (or more like was not looking for it at the time). I'll give it a try. Cheers.
