Set altitude for a marker

  • This example demonstrates how to set the altitude of a marker using the Google Maps JavaScript API.

  • It utilizes the AdvancedMarkerElement and PinElement classes from the marker library to create and position a custom marker.

  • The marker's altitude is specified in meters above the ground within the position object using the LatLngAltitudeLiteral type.

  • The sample provides code snippets in TypeScript, JavaScript, CSS, and HTML to illustrate the implementation.

This example shows setting altitude for a marker.

TypeScript

const mapElement = document.querySelector('gmp-map')!;

async function init() {
    // Request needed libraries.
    const [{ AdvancedMarkerElement, PinElement }] = await Promise.all([
        google.maps.importLibrary('marker'),
        google.maps.importLibrary('maps'),
    ]);

    mapElement.innerMap.setOptions({
        tilt: 67.5,
        heading: 45,
    });

    const pin = new PinElement({
        background: '#4b2e83',
        borderColor: '#b7a57a',
        glyphColor: '#b7a57a',
        scale: 2.0,
    });

    const marker = new AdvancedMarkerElement({
        // Set altitude to 20 meters above the ground.
        position: {
            lat: 47.65170843460547,
            lng: -122.30754,
            altitude: 20,
        },
    });
    marker.append(pin);

    mapElement.append(marker);
}

void init();

JavaScript

const mapElement = document.querySelector('gmp-map');

async function init() {
    // Request needed libraries.
    const [{ AdvancedMarkerElement, PinElement }] = await Promise.all([
        google.maps.importLibrary('marker'),
        google.maps.importLibrary('maps'),
    ]);

    mapElement.innerMap.setOptions({
        tilt: 67.5,
        heading: 45,
    });

    const pin = new PinElement({
        background: '#4b2e83',
        borderColor: '#b7a57a',
        glyphColor: '#b7a57a',
        scale: 2.0,
    });

    const marker = new AdvancedMarkerElement({
        // Set altitude to 20 meters above the ground.
        position: {
            lat: 47.65170843460547,
            lng: -122.30754,
            altitude: 20,
        },
    });
    marker.append(pin);

    mapElement.append(marker);
}

void init();

CSS

/* 
 * Always set the map height explicitly to define the size of the div element
 * that contains the map. 
 */
#map {
    height: 100%;
}

/* 
 * Optional: Makes the sample page fill the window. 
 */
html,
body {
    height: 100%;
    margin: 0;
    padding: 0;
}

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/advanced-markers-altitude
  npm start
