Rendering type (raster and vector)

The Maps JavaScript API offers two different implementations of the map: raster and vector. The raster map is loaded by default, and loads the map as a grid of pixel-based raster image tiles, which are generated by Google Maps Platform server-side, then served to your web app. The vector map is a composed of vector-based tiles, which are drawn at load time on the client-side using WebGL, a web technology that allows the browser to access the GPU on the user's device to render 2D and 3D graphics. The vector map type is recommended for the best user experience, as it provides improved visual fidelity as well as the ability to control tilt and heading on the map. Learn more about vector map features.

Set the rendering type for a map either by specifying the renderingType map option, or by setting the option on an associated map ID. The renderingType option overrides any rendering type settings made by configuring a map ID.

Specify the renderingType option

Use the renderingType option to specify either the raster or vector rendering type for your map (no map ID required). For maps loaded using a div element and JavaScript, the default rendering type is google.maps.RenderingType.RASTER. Take these steps to set the renderingType option:

1. Load the RenderingType library; this can be done when loading the Maps library:

   const { Map, RenderingType } = await google.maps.importLibrary("maps");
   

2. When initializing the map, use the renderingType option to specify either RenderingType.VECTOR or RenderingType.RASTER:

   map = new Map(
     document.getElementById('map'),
     {
       zoom: 4,
       center: position,
       renderingType: RenderingType.VECTOR,
     }
   );
   

When the vector map rendering type is set, you must set the options for the needed features.

• To enable tilt, set the tiltInteractionEnabled map option to true or call map.setTiltInteractionEnabled(true).
• To enable panning, set the headingInteractionEnabled map option to true or call map.setHeadingInteractionEnabled(true).

For maps loaded using the <gmp-map> element, the default rendering type is google.maps.RenderingType.VECTOR, with tilt and heading control enabled. To set the rendering type by using the <gmp-map> element, use the rendering-type attribute.

Use a map ID to set rendering type

You can also specify the rendering type by using a map ID. To create a new map ID, follow the steps in Using Cloud-based Map Styling - Get a map ID. Be sure to set the Map type to JavaScript, and select an option (Vector or Raster). Check Tilt and Rotation to enable tilt and rotation on the map. Doing so will allow you to programmatically adjust these values, and also lets users adjust tilt and heading directly on the map. If the use of tilt or heading will adversely affect your app, leave Tilt and Rotation un- checked so users will not be able to adjust tilt and rotation.

Next, update your map initialization code with the map ID you created. You can find your map IDs on the Maps Management page. Provide a map ID when you instantiate the map using the mapId property as shown here:

map = new google.maps.Map(document.getElementById('map'), {
  center: {lat: -34.397, lng: 150.644},
  zoom: 8,
  mapId: 'MAP_ID'
});
