1. Description

This repository is a collection of 300+ Python examples for using Google Earth Engine with the geemap Python package. I developed these Python examples by converting all the JavaScript examples (except those not yet supported by geemap) from the Google Earth Engine API Documentation.

2. Usage

• Step 1: Sign up for Google Earth Engine.
• Step 2: Follow the instructions here to install geemap and Jupyter notebook.
• Step 3: Open Jupyter notebook and type the following script:

4. Examples

The Table of Contents below mimics the structure of the Google Earth Engine API Documentation. I strongly encourage you to check out the API Documentation if you need an in-depth explanation of each Python example. Please note that the list below does not include all the Python examples contained in this repository. You are welcome to explore the repository and find more examples to suit your needs.
