This product or feature is Experimental (pre-GA). Pre-GA products and features might have limited support, and changes to pre-GA products and features might not be compatible with other pre-GA versions. Pre-GA Offerings are covered by the Google Maps Platform Service Specific Terms. For more information, see the launch stage descriptions. Elevation Standalone Element

The ElevationElement is an HTML element that visually displays elevation data for a single point or a polyline. It shows a graph of elevation along the path set in the path property with an array of latitude and longitude coordinates. Line segments are interpolated between the points of the array, so even a small number of points will still produce a detailed elevation graph.

Set path elevation using coordinates

The following example renders the elevation of a path between two points selected by a set of coordinates, using a gmp-elevation element.

The element is configured for metric measurement using the unit-system attribute:

  <gmp-elevation unit-system="metric"></gmp-elevation>

A querySelector is used to select the elevation element and set its path property with latitude and longitude coordinates:

/** Maps JS loaded callback */
async function init() {
  // Load the Elevation Element from Maps JS
  const {ElevationElement} = await google.maps.importLibrary('elevation');

  // Specify an elevation path to render
  const elevationElement = document.querySelector('gmp-elevation');
  elevationElement.path = [
    {lat: 37.4523, lng: -122.2645},
    {lat: 37.377, lng: -122.4078},
  ];
}

See the complete code example JavaScript

/** Maps JS loaded callback */
async function init() {
  // Load the Elevation Element from Maps JS
  const {ElevationElement} = await google.maps.importLibrary('elevation');

  // Specify an elevation path to render
  const elevationElement = document.querySelector('gmp-elevation');
  elevationElement.path = [
    {lat: 37.4523, lng: -122.2645},
    {lat: 37.377, lng: -122.4078},
  ];
}

init();

Set path elevation using a polyline

The following example renders the elevation of a path based on a user-drawn polyline. It obtains the path from the user's polyline using polyline.getPath().getArray():

      elevationElem.path = polyline.getPath().getArray();

See the complete code example JavaScript

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

async function init() {
  await google.maps.importLibrary('places');
  await google.maps.importLibrary('marker');
  await google.maps.importLibrary('elevation');


  map.innerMap.setOptions({'mapTypeControl': true, 'clickableIcons': false});

  findCurrentLocation();
  drawPolyline();
}

async function drawPolyline() {
  const {DrawingManager} = await google.maps.importLibrary('drawing');
  const drawingManager = new DrawingManager({
    drawingMode: google.maps.drawing.OverlayType.POLYLINE,
    drawingControl: true,
    drawingControlOptions: {
      position: google.maps.ControlPosition.TOP_CENTER,
      drawingModes: [google.maps.drawing.OverlayType.POLYLINE]
    },
    polylineOptions: {geodesic: true, strokeColor: '#5491f5', strokeWeight: 6}
  });

  drawingManager.setMap(map.innerMap);

  drawingManager.addListener('polylinecomplete', (polyline) => {
    console.log('complete');
    console.log(polyline.getPath().getArray());
    elevationElem.path = polyline.getPath().getArray();
    polyline.addListener('click', (e) => {
      console.log(e);
    });
  });
}

async function findCurrentLocation() {
  const {LatLng} = await google.maps.importLibrary('core');
  if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(
        (position) => {
          const pos =
              new LatLng(position.coords.latitude, position.coords.longitude);
          map.innerMap.panTo(pos);
          map.innerMap.setZoom(16);
        },
        () => {
          console.log('The Geolocation service failed.');
          map.innerMap.setZoom(16);
        },
    );
  } else {
    console.log(`Your browser doesn't support geolocation`);
    map.innerMap.setZoom(16);
  }
}
