How do I cite geemap in publications¶
Wu, Q., (2020). geemap: A Python package for interactive mapping with Google Earth Engine. The Journal of Open Source Software, 5(51), 2305. https://doi.org/10.21105/joss.02305

Why does geemap use two plotting backends: folium and ipyleaflet¶
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.eefolium as geemap. If you are using geemap with a local Jupyter notebook server, you can
import geemap, which provides more functionalities for capturing user input (e.g., mouse-clicking and moving).
Why the interactive map does not show up¶
If the interactive map does not show up on Jupyter notebook and JupyterLab, it is probably because the ipyleaflet extentsion is not installed properly. For Jupyter notebook, try running the following two commands within your geemap conda environment:
For JupyterLab, try running the following command within your geemap conda environment:
How to use geemap in countries where Google Services are blocked¶
If you are trying to use geemap in coutries where Gooogle Services are blocked (e.g., China), you will need a VPN. Use
geemap.set_proxy(port=your-port-number) to connect to Earth Engine servers. Otherwise, you might encounter a connection timeout issue.
