hide local listings from google maps api

you can set them invisible by setting the map style properly. See

http://code.google.com/apis/maps/documentation/javascript/styling.html

and

http://code.google.com/intl/pl/apis/maps/documentation/javascript/reference.html#MapTypeStyleFeatureType

sth like that should do the trick (though not tested):

var noPoi = [
{
    featureType: "poi",
    stylers: [
      { visibility: "off" }
    ]   
  }
];

map.setOptions({styles: noPoi});
