Create markers

The following example creates a marker over the Google office in Mountain View.

Read the documentation.

JavaScript

async function init() {
    // Make sure the Marker3DElement is included.
    const { Map3DElement, Marker3DElement } =
        await google.maps.importLibrary('maps3d');

    const map = new Map3DElement({
        center: { lat: 37.4239163, lng: -122.0947209, altitude: 0 },
        tilt: 67.5,
        range: 1000,
        mode: 'SATELLITE',
    });

    const marker = new Marker3DElement({
        position: { lat: 37.4239163, lng: -122.0947209, altitude: 50 }, // (Required) Marker must have a lat / lng, but doesn't need an altitude.
        altitudeMode: 'ABSOLUTE', // (Optional) Treated as CLAMP_TO_GROUND if omitted.
        extruded: true, // (Optional) Draws line from ground to the bottom of the marker.
        label: 'Basic Marker', // (Optional) Add a label to the marker.
    });

    map.append(marker); // The marker must be appended to the map.
    document.body.append(map);
}

void init();

CSS

/* 
 * Always set the map height explicitly to define the size of the div element
 * that contains the map.

html,
body {
    height: 100%;

Clone Sample

Git and Node.js are required to run this sample locally. Follow these instructions to install Node.js and NPM. You will also need a Google Maps API key.

The following commands clone the repository, install dependencies, and copy the environment file.

  git clone https://github.com/googlemaps-samples/js-api-samples.git
  cd js-api-samples
  npm i
  cp .env.template .env

Once you copy the environment file, make sure to open the .env file and replace <Insert your own development API key here> with your actual API key before starting the sample.

  cd samples/3d-simple-marker
  npm start
