Question

I am trying to generate pins over the map of my database coordinates by using fusion table and I want to generate only within 1 mile area circle around the specific location. To get 1 mile area’s coordinates similar to my db coordinates I’ve to put condition of < and > to fusion table but I don’t know how to get all the coordinates within 1 mile area circle or what should be the value for condition in query. Can any one please help me to figure out, it’ll really appreciable.

You haven’t provided any code, so I’m not exactly sure what you want to do. But the Fusion Table ST_INTERSECTS operator should do what you want. Look for <spatial_condition>.

  var where = "ST_INTERSECTS('location_col',CIRCLE(LATLNG(31.954109,-115.441528), radius_in_meters) ) )";

  var qryOpts = {
   query: {
   select: location_col,
      from: table_id,
      where: where
    }
 };
 ft_layer.setOptions(qryOpts);
