"## Install Earth Engine API and geemap\n",
"Install the [Earth Engine Python API](https://developers.google.com/earth-engine/python_install) and [geemap](https://github.com/giswqs/geemap). The **geemap** Python package builds on the [ipyleaflet](https://github.com/jupyter-widgets/ipyleaflet) package and implements several methods for displaying Earth Engine data layers, such as `Map.addLayer()`, `Map.setCenter()`, and `Map.centerObject()`.\n",
"The following script checks if the geemap package has been installed. If not, it will install geemap, which automatically install its dependencies, including earthengine-api and ipyleaflet."
