This example shows how to build a simple Google App Engine web application that communicates with Google Earth Engine. Upon successful deployment, you will see a webpage with a Google map showing the SRTM DEM zoomed into the east coast of Australia.

Download Hello World

Download the Earth Engine API repository from GitHub:

git clone https://github.com/google/earthengine-api.git

Navigate to the Hello World example code:

cd ./python/examples/AppEngine/hello-world/

Create your own project

Each App Engine app needs its own project. The project ID for the default instance of this app is hello-earth-engine. To deploy your own instance, you'll need to create a new project with a different ID.

To create an App Engine project for your app:

Open the Google Developers Console.
Click Create Project.
Enter a project name and a project ID.
Click Create.

Once you've selected a project ID, update your app.yaml file.

Set up a service account

Create a service account.
Download a P12 private key from the Google Developers Console.
Convert the private key of that service account to a .pem file:
openssl pkcs12 -in downloaded-privatekey.p12 -nodes -nocerts > privatekey.pem
Copy the .pem file into the directory that has your app.yaml file.
Update config.py file with your service account email address.

Build the app

From within the hello-world folder, run:

. ./build.sh

This script will build the app and fetch all its dependencies. It will also install the Google Cloud SDK if necessary.

Run the app!

From within the hello-world folder, run:

dev_appserver.py ./
