This example shows setting altitude for a marker.
Read the
[documentation](https://developers.google.com/maps/documentation/javascript/advanced-markers/collision-behavior.md.txt#set_marker_altitude).
### TypeScript
```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
```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
```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](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm)
to install Node.js and NPM. You will also need a [Google Maps API key](https://developers.google.com/maps/documentation/javascript/get-api-key.md.txt).
The following commands clone the repository, install dependencies, and copy the environment file.
```javascript
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 `` with your actual API key before starting the sample.
```javascript
cd samples/advanced-markers-altitude
npm start
```
