The EarthEngineLayer connects Google Earth Engine to, making it possible to visualize planetary-scale geospatial datasets in a JavaScript application.

To use this layer, you need to sign in with an EarthEngine-enabled Google Account. Visit here to sign up.

This particular example uses the React bindings but the EarthEngineLayer can of course also be used with the pure JavaScript and scripting APIs:

import React from 'react';
import DeckGL from '';
import {EarthEngineLayer} from '';
import ee from '@google/earthengine';

export default class App extends React.Component {
  constructor(props) {
    this.state = {eeObject: null};

  async _onLoginSuccess(user, loginProvider) {
    const token = 'Google OAuth2 access token'
    await EarthEngineLayer.initializeEEApi({clientId: EE_CLIENT_ID, token});
    this.setState({eeObject: ee.Image('CGIAR/SRTM90_V4')});

  render() {
    const {viewport} = this.props;
    const {eeObject} = this.state;
    const visParams = {
      min: 0,
      max: 4000,
      palette: ['006633', 'E5FFCC', '662A00', 'D8D8D8', 'F5F5F5']
    const layers = [new EarthEngineLayer({eeObject, visParams})];
    return (
        <DeckGL controller {...viewport} layers={layers}/>


To install the dependencies from NPM:

npm install @google/earthengine
# or
npm install @google/earthengine
import {EarthEngineLayer} from '';
new EarthEngineLayer({});

Static Methods

async initializeEEApi({clientId?: string, token?: string})

Can be called to initialize the earth engine API. Calls, ee.initialize() or ee.setToken(), and returns a Promise that resolves when authentication and initialization is completed and the EE API is ready to use.

This method is just a convenience, it can be replaced with direct calls to the EE API.


  • clientId A valid Google clientId that has been authenticated with the earthengine scope and set up to whitelist the 'origin' URL that the app will be served on.
  • token Alternatively, a pre-generated OAuth2 access token.


Inherits all properties from base Layer and from the TileLayer. If rendering images, inherits all properties from the BitmapLayer. If rendering vector data, inherits all properties from the GeoJsonLayer.

Authentication Options

token (String, optional)
  • Default: null

A valid Google OAuth2 access token. Unnecessary from pydeck or if using initializeEEApi described above.

Data Options

eeObject (EarthEngine Object|String)
  • Default: null

Either an EarthEngine JavaScript API object, or a serialized string representing an object (created with, e.g. ee.Image.serialize()).

By default, getMap is called on the object, and image tiles are displayed representing the object. You can pass asVector or animate for alternative rendering.

visParams (Object, optional)
  • Default: null

An object representing the visualization parameters passed to Earth Engine. See Earth Engine documentation for more information on supported parameters. Alternatively, you can style objects by using the .style() function for FeatureCollection or ImageCollection objects.

Unused when asVector is true.

selectors (Array of String, optional)
  • Default: []

Names of additional properties to download when asVector is true.

By default, only the geometries of the FeatureCollection are downloaded. In order to apply data-driven styling using GeoJsonLayer styling properties, you need to specify those property names here.

Render Options

asVector (Boolean, optional)
  • Default: false

If true, render vector data using the GeoJsonLayer.

Rendering as vector is only possible for ee.FeatureCollection objects; an error will be produced if asVector is set to true when another object type is passed.

When asVector is set, the GeoJSON representation of the FeatureCollection is downloaded, which can include very precise geometries. As such, beware of large downloads: the Earth Engine backend may return no data if the output would be larger than 100MB.

To reduce the dataset size, use filter expressions on the FeatureCollection object before passing it to EarthEngineLayer.

animate (Boolean, optional)
  • Default: false

If true, render an animated ImageCollection.

Rendering an animation is only possible for ee.ImageCollection objects; an error will be produced if animate is set to true when another object type is passed.

The ImageCollection should be filtered and sorted in the order desired for the animation. If an ImageCollection contains 20 images, the animation will contain those images as individual frames of the animation, in the same order. Earth Engine has an upper limit of 100 animation frames.

animationSpeed (Number, optional)
  • Default: 12

If animate is true, animationSpeed represents the number of frames per second. Keeping this constant implies that animations will play at the same speed; an ImageCollection with more frames will have a longer loop than one with fewer frames.
