This library is deprecated. We have created a new library called CartoDB.js that includes all the funcionality of this library plus many more things. This library isn't going to be updated anymore. If you have any questions don't hesitate to send us an email to [email protected].

This library allows you to use your own CartoDB tables with Google Maps v3.

Using the library is really easy. It accepts the following parameters to manage the behavior of your CartoDB layers:

If you want to get a feature clicked || hover data (via the interactivity parameter), the columns must be in a string separated by commas. If you don't want to write the name of the table several times, you can use {{table_name}} in the query or tile_style parameters. We strongly recommend the use of the files available in this repository. These are tested, and if you decide use updated ones, the library could not work.

There are several usages of this library in examples folder.

First of all add the necessary script and css files:

<link href="css/cartodb-gmapsv3.css" rel="stylesheet" type="text/css">
<link href="http://code.google.com/apis/maps/documentation/javascript/examples/default.css" rel="stylesheet" type="text/css" />          
<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
<script type="text/javascript" src="js/wax.g.min-6.2.0-touched.js"></script>
<script type="text/javascript" src="dist/cartodb-gmapsv3-min.js"></script>

• We strongly recommend to use the library files we have in this repository, they are fully tested.

When the document is loaded, start creating the map:

var map = new google.maps.Map(document.getElementById('map'), {
  center: new google.maps.LatLng(20, 0),
  zoom: 3,
  mapTypeId: google.maps.MapTypeId.ROADMAP,
  mapTypeControl: false
});

And then add the CartoDB layer:

var cartodb_gmapsv3 = new CartoDBLayer({
  map: map,
  user_name:'examples',
  table_name: 'earthquakes',
  query: "SELECT * FROM {{table_name}}",
  layer_order: "top",
  tile_style: "#{{table_name}}{marker-fill:red}",
  interactivity: "cartodb_id, magnitude",
  featureClick: function(feature, latlng, pos, data) {alert(feature)},
  featureOut: function() {},
  featureOver: function(feature, latlng, pos, data) {},
  auto_bound: true
});

New funcionalities are coming, in the meantime you can use:

• setMap: Attach the layer to the map or remove it. Example: cartodb_gmapsv3.setMap(null);
• hide: Hide the cartodb layer from the map. Example: cartodb_gmapsv3.hide();
• show: Show again the cartodb layer in the map. Example: cartodb_gmapsv3.show();
• setInteraction: Set the interaction of your layer to true or false. Example: cartodb_gmapsv3.setInteraction(false);
• setLayerOrder: Change the order of the CartoDB layer. Example: cartodb_gmapsv3.setOrder("top"); cartodb_gmapsv3.setOrder("bottom"); cartodb_gmapsv3.setOrder(2);
• setQuery: Change the query parameter for the layer Example: cartodb_gmapsv3.setQuery("SELECT * FROM {{table_name}} WHERE cartodb_id > 10");
• setStyle: Change the style of the layer tiles Example: cartodb_gmapsv3.setStyle("#{{table_name}}{marker-fill:blue}");
• isVisible: Get the visibility of the layer. Example: cartodb_gmapsv3.isVisible();
• isAdded: Returns if the layer belongs to the maps or not. Example: cartodb_gmapsv3.isAdded();
• setInteractivity: Change the columns you want to get data (it needs to reload the tiles) Example: cartodb_gmapsv3.setInteractivity("cartodb_id, the_geom, magnitude");
• setOptions: Change any parameter at the same time refreshing the tiles once Example: cartodb_gmapsv3.setOptions({query: "SELECT * FROM {{table_name}} WHERE cartodb_id<100", interactivity: "cartodb_id,the_geom,magnitude"});
• setOpacity: Change the opacity of the layer Example: cartodb_gmapsv3.setOpacity(0.2);
• setBounds: Set bounds in the map using a new query or the default one Example: cartodb_gmapsv3.setBounds("SELECT * FROM {{table_name}} WHERE cartodb_id < 100");
