Customize markers

The following example shows how to customize markers in 3D Maps in Maps JavaScript.

Read the documentation.

JavaScript

async function init() {
    const [
        { Map3DElement, Marker3DElement, Label3DElement },
        { PinElement, CollisionBehavior },
    ] = await Promise.all([
        google.maps.importLibrary('maps3d'),
        google.maps.importLibrary('marker'),
    ]);

    const map = new Map3DElement({
        center: { lat: 37.4176, lng: -122.02, altitude: 0 },
        tilt: 67.5,
        range: 7000,
        mode: 'SATELLITE',
    });

    // Change the border color.
    const pinBorder = new PinElement({
        borderColor: '#FFFFFF',
    });
    const markerWithBorder = new Marker3DElement({
        position: { lat: 37.415, lng: -122.035 },
    });
    markerWithBorder.append(pinBorder);

    // Add a label.
    const markerWithLabel = new Marker3DElement({
        position: { lat: 37.419, lng: -122.03 },
        label: 'Simple label',
    });

    // Adjust the scale.
    const pinScaled = new PinElement({
        scale: 1.5,
    });
    const markerWithScale = new Marker3DElement({
        position: { lat: 37.419, lng: -122.02 },
    });
    markerWithScale.append(pinScaled);

    // Change the glyph color.
    const pinGlyph = new PinElement({
        glyphColor: 'white',
    });
    const markerWithGlyphColor = new Marker3DElement({
        position: { lat: 37.415, lng: -122.025 },
    });
    markerWithGlyphColor.append(pinGlyph);

    // Change many elements together and extrude marker.
    const pinTextGlyph = new PinElement({
        background: '#F0F6FC',
        glyphText: 'E',
        glyphColor: 'red',
        borderColor: '#0000FF',
    });
    const markerWithGlyphText = new Marker3DElement({
        position: { lat: 37.415, lng: -122.015, altitude: 50 },
        extruded: true,
        altitudeMode: 'RELATIVE_TO_GROUND',
    });
    markerWithGlyphText.append(pinTextGlyph);

    // Change a marker's altitude and add an extrusion.
    const extrudedMarker = new Marker3DElement({
        position: { lat: 37.4239163, lng: -122.0947209, altitude: 100 },
        altitudeMode: 'RELATIVE_TO_GROUND',
        extruded: true,
    });

    // Hide the glyph.
    const pinNoGlyph = new PinElement({
        glyphText: '',
    });
    const markerWithNoGlyph = new Marker3DElement({
        position: { lat: 37.415, lng: -122.005 },
    });
    markerWithNoGlyph.append(pinNoGlyph);
    // Change the background color.
    const pinBackground = new PinElement({
        background: '#FBBC04',
    });

    const markerWithBackground = new Marker3DElement({
        position: { lat: 37.419, lng: -122.01 },
    });
    markerWithBackground.append(pinBackground);

    const markerWithIndependentLabel = new Marker3DElement({
        position: { lat: 37.423, lng: -122.015 },
    });
    markerWithIndependentLabel.id = 'marker-1';
    const label = new Label3DElement({
        collisionBehavior: CollisionBehavior.OPTIONAL_AND_HIDES_LOWER_PRIORITY,
        for: 'marker-1',
    });
    label.append('Independent label example');
    map.append(markerWithIndependentLabel);
    map.append(label);

    map.append(markerWithLabel);
    map.append(markerWithScale);
    map.append(markerWithBackground);
    map.append(markerWithBorder);
    map.append(markerWithGlyphColor);
    map.append(markerWithGlyphText);

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-marker-customization
  npm start
