Create markers

Page Summary

• Learn how to add simple or customized markers, including labels, scaling, and color adjustments to Photorealistic 3D Maps.

• Discover techniques to replace default icons with custom graphics using SVGs, PNGs, or Place icons, enhancing marker visualization.

• Explore creating interactive markers that respond to user clicks, providing an engaging user experience in the 3D map environment.

• Understand how to extrude markers to add a third dimension, allowing for more realistic and informative map representations.

• Gain insights into controlling marker collision behavior, ensuring optimal marker visibility and preventing overlapping in crowded areas, and understand how to remove markers from the map when necessary.

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

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);
}

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
