Google Maps API – Pan and Change Zoom to Show Fusion Tables Query Results

google mapsgoogle-fusion-tables

I've created this map — https://s3.amazonaws.com/pdb.files/lookup_auto2.html — using Google Fusion Tables and Google Maps API. I'm attempting to modify the code so that the map will pan and zoom after executing the query. It seems that I need to use either the fitBounds function to display the bounds of the results, or something simpler like this: 

// Change the center and zoom of the map
      map.setCenter(results[0].geometry.location);
      map.setZoom(10);

I'd prefer the second option so that I can set a consistent zoom level for each query. Any pointers or references for completing this are much appreciated.

Add a spatial search to your code:

FUSION TABLES allows ST_INTERSECT to be performed full reference: http://code.google.com/apis/fusiontables/docs/developers_reference.html#Select (see <spatial_condition> )

      // OPTIONAL: find the new map bounds, and run a spatial query to return
  // Fusion Tables results within those bounds. 
  sw = map.getBounds().getSouthWest();
  ne = map.getBounds().getNorthEast();
  layer.setOptions({
    query: {
      select: 'lat',
      from: tableid,
      where: "ST_INTERSECTS(lat, RECTANGLE(LATLNG(" + sw.lat() + "," + sw.lng() + "), LATLNG(" + ne.lat() + "," + ne.lng() + ")))"
    }
  });
