AI-generated Key Takeaways
-
This example demonstrates how to set the altitude of a marker using the Google Maps JavaScript API.
-
It utilizes the
AdvancedMarkerElement
andPinElement
classes from themarker
library to create and position a custom marker. -
The marker's altitude is specified in meters above the ground within the
position
object using theLatLngAltitudeLiteral
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
let map; async function initMap() { // Request needed libraries. const { Map } = await google.maps.importLibrary("maps") as google.maps.MapsLibrary; const { AdvancedMarkerElement, PinElement } = await google.maps.importLibrary("marker") as google.maps.MarkerLibrary; map = new Map(document.getElementById('map') as HTMLElement, { center: {lat: 47.65196191658531, lng: -122.30716770065949}, zoom: 19, tilt: 67.5, heading: 45, mapId: '6ff586e93e18149f', }); const pin = new PinElement({ background: '#4b2e83', borderColor: '#b7a57a', glyphColor: '#b7a57a', scale: 2.0, }); const markerView = new AdvancedMarkerElement({ map, content: pin.element, // Set altitude to 20 meters above the ground. position: { lat: 47.65170843460547, lng: -122.30754, altitude: 20 } as google.maps.LatLngAltitudeLiteral, }); } initMap();
JavaScript
let map; async function initMap() { // Request needed libraries. const { Map } = await google.maps.importLibrary("maps"); const { AdvancedMarkerElement, PinElement } = await google.maps.importLibrary("marker"); map = new Map(document.getElementById('map'), { center: { lat: 47.65196191658531, lng: -122.30716770065949 }, zoom: 19, tilt: 67.5, heading: 45, mapId: '6ff586e93e18149f', }); const pin = new PinElement({ background: '#4b2e83', borderColor: '#b7a57a', glyphColor: '#b7a57a', scale: 2.0, }); const markerView = new AdvancedMarkerElement({ map, content: pin.element, // Set altitude to 20 meters above the ground. position: { lat: 47.65170843460547, lng: -122.30754, altitude: 20 }, }); } initMap();
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; }
