A Python package for interactive mapping with Google Earth Engine, ipyleaflet, and ipywidgets.

geemap is a Python package for interactive mapping with Google Earth Engine (GEE), which is a cloud computing platform with a multi-petabyte catalog of satellite imagery and geospatial datasets. During the past few years, GEE has become very popular in the geospatial community and it has empowered numerous environmental applications at local, regional, and global scales. GEE provides both JavaScript and Python APIs for making computational requests to the Earth Engine servers. Compared with the comprehensive documentation and interactive IDE (i.e., GEE JavaScript Code Editor) of the GEE JavaScript API, the GEE Python API has relatively little documentation and limited functionality for visualizing results interactively. The geemap Python package was created to fill this gap. It is built upon ipyleaflet and ipywidgets, and enables users to analyze and visualize Earth Engine datasets interactively within a Jupyter-based environment.

geemap is intended for students and researchers, who would like to utilize the Python ecosystem of diverse libraries and tools to explore Google Earth Engine. It is also designed for existing GEE users who would like to transition from the GEE JavaScript API to Python API. The automated JavaScript-to-Python conversion module of the geemap package can greatly reduce the time needed to convert existing GEE JavaScripts to Python scripts and Jupyter notebooks.

To use geemap, you must first sign up for a Google Earth Engine account.

geemap is available on PyPI. To install geemap, run this command in your terminal:

pip install geemap

geemap is also available on conda-forge. If you have Anaconda or Miniconda installed on your computer, you can create a conda Python environment to install geemap:

conda create -n gee python=3.8
conda activate gee
conda install geopandas
conda install mamba -c conda-forge
mamba install geemap xarray_leaflet -c conda-forge

Optionally, you can install Jupyter notebook extensions, which can improve your productivity in the notebook environment. Some useful extensions include Table of Contents, Gist-it, Autopep8, Variable Inspector, etc. See this post for more information.

conda install jupyter_contrib_nbextensions -c conda-forge

If you have installed geemap before and want to upgrade to the latest version, you can run the following command in your terminal:

pip install -U geemap

If you use conda, you can update geemap to the latest version by running the following command in your terminal:

conda update -c conda-forge geemap

To install the development version from GitHub using Git, run the following command in your terminal:

pip install git+

To install the development version from GitHub directly within Jupyter notebook without using Git, run the following code:

import geemap

To use geemap in a Docker container, check out the following docker containers with geemap installed.

To use geemap in a Docker container, check out ee-jupyter-contrib or this page.


Important note: A key difference between ipyleaflet and folium is that ipyleaflet is built upon ipywidgets and allows bidirectional communication between the front-end and the backend enabling the use of the map to capture user input, while folium is meant for displaying static data only (source). Note that Google Colab currently does not support ipyleaflet (source). Therefore, if you are using geemap with Google Colab, you should use import geemap.foliumap. If you are using geemap with binder or a local Jupyter notebook server, you can use import geemap, which provides more functionalities for capturing user input (e.g., mouse-clicking and moving).

More GEE Tutorials are available on my YouTube channel.

More examples can be found at another repo: A collection of 300+ Jupyter Python notebook examples for using Google Earth Engine with interactive mapping.

Converting GEE JavaScripts to Python scripts and Jupyter notebooks

Launch an interactive notebook with Google Colab. Keep in mind that the conversion might not always work perfectly. Additional manual changes might still be needed. ui and chart are not supported. The source code for this automated conversion module can be found at

import os
from geemap.conversion import *

# Create a temporary working directory
work_dir = os.path.join(os.path.expanduser('~'), 'geemap')
# Get Earth Engine JavaScript examples. There are five examples in the geemap package folder.
# Change js_dir to your own folder containing your Earth Engine JavaScripts, such as js_dir = '/path/to/your/js/folder'
js_dir = get_js_examples(out_dir=work_dir)

# Convert all Earth Engine JavaScripts in a folder recursively to Python scripts.
js_to_python_dir(in_dir=js_dir, out_dir=js_dir, use_qgis=True)
print("Python scripts saved at: {}".format(js_dir))

# Convert all Earth Engine Python scripts in a folder recursively to Jupyter notebooks.
nb_template = get_nb_template()  # Get the notebook template from the package folder.
py_to_ipynb_dir(js_dir, nb_template)

# Execute all Jupyter notebooks in a folder recursively and save the output cells.

Interactive mapping using GEE Python API and geemap

Launch an interactive notebook with Google Colab. Note that Google Colab currently does not support ipyleaflet. Therefore, you should use import geemap.foliumap instead of import geemap.

# Installs geemap package
import subprocess

        import geemap
except ImportError:
        print('geemap package not installed. Installing ...')
        subprocess.check_call(["python", '-m', 'pip', 'install', 'geemap'])

# Checks whether this notebook is running on Google Colab
        import google.colab
        import geemap.foliumap as emap
        import geemap as emap

# Authenticates and initializes Earth Engine
import ee

except Exception as e:

# Creates an interactive map
Map = emap.Map(center=[40,-100], zoom=4)

# Adds Earth Engine dataset
image = ee.Image('USGS/SRTMGL1_003')

# Sets visualization parameters.
vis_params = {
        'min': 0,
        'max': 4000,
        'palette': ['006633', 'E5FFCC', '662A00', 'D8D8D8', 'F5F5F5']}

# Prints the elevation of Mount Everest.
xy = ee.Geometry.Point([86.9250, 27.9881])
elev = image.sample(xy, 30).first().get('elevation').getInfo()
print('Mount Everest elevation (m):', elev)

# Adds Earth Engine layers to Map
Map.addLayer(image, vis_params, 'SRTM DEM', True, 0.5)
Map.addLayer(xy, {'color': 'red'}, 'Mount Everest')
Map.setCenter(100, 40, 4)
# Map.centerObject(xy, 13)

# Display the Map

Get Started!

Ready to contribute? Here's how to set up geemap for local development.

  1. Fork the geemap repo on GitHub.

  2. Clone your fork locally:

    $ git clone [email protected]:your_name_here/geemap.git
  3. Install your local copy into a virtualenv. Assuming you have virtualenvwrapper installed, this is how you set up your fork for local development:

    $ mkvirtualenv geemap
    $ cd geemap/
    $ python develop
  4. Create a branch for local development:

    $ git checkout -b name-of-your-bugfix-or-feature

    Now you can make your changes locally.

  5. When you're done making changes, check that your changes pass flake8 and the tests, including testing other Python versions with tox:

    $ flake8 geemap tests
    $ python test or pytest
    $ tox

    To get flake8 and tox, just pip install them into your virtualenv.

  6. Commit your changes and push your branch to GitHub:

    $ git add .
    $ git commit -m "Your detailed description of your changes."
    $ git push origin name-of-your-bugfix-or-feature
  7. Submit a pull request through the GitHub website.

Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

  1. The pull request should include tests.
  2. If the pull request adds functionality, the docs should be updated. Put your new functionality into a function with a docstring, and add the feature to the list in README.rst.
  3. The pull request should work for Python 3.6, 3.7 and 3.8, and for PyPy. Check and make sure that the tests pass for all supported Python versions.


To run a subset of tests:

$ python -m unittest tests.test_geemap


A reminder for the maintainers on how to deploy. Make sure all your changes are committed (including an entry in HISTORY.rst). Then run:

$ bump2version patch # possible: major / minor / patch
$ git push
$ git push --tags

Travis will then deploy to PyPI if tests pass.
