In this episode of the MapScaping Podcast, Kushang Wu discusses GMAP, an open-source Python library for interactive mapping with Google Earth Engine. He explores the development process, the differences between client and server objects in GIS, and the capabilities and limitations of GMAP. He also emphasizes the impact of sharing geospatial tools and resources and provides links for further exploration.
GeeMap is an open-source Python library that simplifies the process of working with Google Earth Engine in Python and offers tools for data visualization and analysis.
GeeMap integrates popular mapping libraries like Folium and ipyleaflet for easy visualization of geospatial data.
GeeMap has been officially integrated into Google Colab, making it more accessible and providing options for saving authentication tokens.

GMAP: A Python Package for Geospatial Analysis with Google Earth Engine
GMAP is an open-source Python package that enables interactive visualization and analysis with Google Earth Engine. It allows users to easily perform large-scale computations using Google Earth Engine and visualize the results in a Jupyter environment. The package integrates popular mapping libraries like Folium and ipyleaflet for visualization, and provides a user-friendly interface for accessing the vast Earth Engine data catalog. GMAP simplifies the process of working with Google Earth Engine in Python and offers tools for comparing data layers, creating time sliders, and more.
What is GMAP and Why Was It Created?
GMAP was created by Kushang Wu, an associate professor at the University of Tennessee, to address the limitations of the Google Earth Engine Python API. The API lacked comprehensive documentation and support for data visualization, making it difficult for Python users to visualize data within the Earth Engine. Kushang wanted to build a tool that would allow Python users to easily visualize data in the browser and integrate it with their computational workflows. He created GMAP as an open-source project and shared it with the geospatial community to help others overcome the challenges he faced. The project gained popularity and has since been officially adopted and supported by the Google Earth Engine team.
Key Features and Workflow of GMAP
GMAP offers a wide range of features and simplifies the workflow of geospatial analysis with Google Earth Engine. Users can create interactive maps using the GMAP Python package and add layers from the Earth Engine data catalog or local datasets. The package integrates popular mapping libraries like Folium and ipyleaflet for easy visualization. Users can perform large-scale computations using Google Earth Engine with the browser-based interface, and visualize the results in a Jupyter environment. GMAP streamlines the process of accessing and analyzing geospatial data, making it accessible to a broader audience.
Integration with Google Colab and Cloud Computing
GMAP has been officially integrated into Google Colab, making it even more accessible for users. With a simple click, users can open GMAP in a Google Colab notebook and start using its functionality without any installation. Google Colab also provides options for saving authentication tokens, making it easier to use GMAP without frequent authentication. GMAP leverages cloud computing capabilities of Google Earth Engine, allowing users to perform computation on the fly, access the massive Earth Engine data catalog, and quickly generate visualizations.
Contributing to GMAP and Further Resources
The GMAP project is open-source and welcomes contributions from the geospatial community. Users can access the GMAP GitHub repository, which contains the core functionality and a collection of open-source packages developed by Kushand Wu. The repository serves as a central hub for discussions, bug reports, and feature requests. Kushand is actively involved in the community and readily supports users with their questions and feedback. He also shares content and tutorials on his website, gishub.org, and social media platforms to help users learn and leverage the capabilities of GMAP.
