Introducing the Earth Engine Google Developer Experts (GDEs)

Posted by Tyler Erickson, Developer Advocate, Google Earth Engine

One of the greatest things about Earth Engine is the vibrant community of developers who openly share their knowledge about the platform and how it can be used to address real-world sustainability issues. To recognize some of these exceptional community members, in 2022 we launched the initial cohort of Earth Engine Google Developer Experts (GDEs). You can view the current list of Earth Engine GDEs on the GDE Directory page.

What makes an Earth Engine expert? Earth Engine GDEs are selected based on their expertise in the Earth Engine product (of course), but also for their knowledge sharing. They share their knowledge in many ways, including answering questions from other developers, writing tutorials and blogs, teaching in settings spanning from workshops to university classes, organizing meetups and conference sessions that allow others to share their work, building extensions to the platform, and so much more!

To learn more about the Google Developer Experts program and the Earth Engine GDEs, go to https://developers.google.com/community/experts.

Now that it is 2023, we are re-opening the application process for additional Earth Engine GDEs. If you’re interested in being considered, you can find information about the process in the GDE Program Application guide.

Google Earth Engine GDE Liza Goldberg uses tech to fight climate change

Liza Goldberg learned to code through Google Earth Engine at age fourteen, when her mentors at NASA, where she was an intern, introduced the tool as a way to model global trends in environmental change. Liza, who had arrived at NASA with no coding or remote sensing experience, gradually gained expertise in the platform, thanks to strong mentorship, Google training, and guidance from the Google Earth Engine developer community. The fact that Google Earth Engine is built for scientists and has a clear world impact aligned with Liza’s commitment to using technology to combat climate change. “Earth Engine enabled me to write each line of code knowing that my algorithms could eventually make true change in climate monitoring,” she says. “The visualization-focused interface of Earth Engine showed me that coding could be simple, data focused, and broadly influential across all fields of climate science.”

Becoming a GDE


Liza used Earth Engine for years at her NASA internship, which grew into a part-time research position. In 2022, her longtime collaborator on the Google Earth Engine team, Tyler Erickson, nominated Liza for the GDE Program, and she became a GDE in April 2022.

“When I found out about my nomination, I felt admittedly nostalgic,” she says. “I remembered my 14-year-old excitement when I first opened Earth Engine – how the whole world suddenly seemed open to me. Becoming a GDE felt like coming full-circle; in many ways, I grew up with Earth Engine.”

Liza hopes her GDE role encourages other young students to explore new technologies.

“I hope that my position as a GDE can show other young students - particularly women - that starting with no knowledge of a field doesn’t need to be a barrier towards accomplishing your ultimate goals,” she says. “As the youngest female GDE in North America, I hope to break the barriers that prevent other young women from chasing down their passions in male-dominated arenas.”

In her GDE role, Liza is collaborating with Google India and the Indian Institutes of Technology (IIT) to launch a series of Google Earth Engine trainings across the country, building technical capacity among the next generation of climate scientists.

“We’ll be guiding students in basic geospatial skills, preparing them for fellowships with partner conservation organizations in the coming year,” she says. “I’m optimistic that this program can distribute the advanced computing power of Earth Engine to students who can leverage its tools for local-to-national scale change.”

Working at NASA


Liza has continued her longtime work on global mangrove ecosystem vulnerability at NASA, analyzing the impact of various mangrove protection and governance models on the degree of forest disturbance. Liza is spending the summer in West Africa with her NASA colleagues, completing mangrove-based fieldwork and delivering Google Earth Engine trainings to academic and conservation institutions in the area.

Liza is also currently leading The Atlantis Project, a global initiative to enable the Earth’s most climate vulnerable populations to develop community disaster response capacity, at NASA.

“We’re using Google Earth Engine to map the key barriers toward a community’s recovery from impending climatic disasters, enabling aid organizations to more effectively target the right stressors in the right communities,” she says. “We’re currently training highly flood vulnerable communities in early warning system deployment and household disaster preparation and response.”

Her team is also collaborating with NGOs in India to educate communities on their post-disaster aid rights.

Studying at Stanford


Liza is also a college student, studying Earth Systems and international development policy at Stanford University.

“I seek to better understand how climate change can further trap the extreme poor in cycles of lagging economic growth,” she says. “I will then combine my remote sensing knowledge with this policy and climate change background to develop new solutions for climate adaptation across the developing world.”

Ultimately, Liza seeks to use technology to help the planet’s most climate-vulnerable populations respond most effectively to climate impacts.

“I’ve found that satellite analysis is among the most effective ways to tackle many of these challenges, but I’ve fallen in love with the problem, not any particular solution to it,” she says. “In my professional future, I seek to continue applying satellite tech towards building these critical bridges between technical capacity and on-the-ground need.”

Bring the world’s changing forests inside the classroom



(Cross-posted on Google Lat Long Blog.)

Forests are the mighty lungs of our planet. They absorb carbon dioxide, and emit oxygen on which all people and animals on Earth rely. For the sake of our future, it is critical that all people, including the next generation, understand our global forests in order to manage them sustainably. Today, Science in the Classroom, Dr. Matt Hansen of the University of Maryland, and Google Earth Engine are presenting Global Forest Change Explorer to help engage young people in forest conservation.

The Global Forest Change Explorer website contains maps that are available for interactive analysis as well as an accompanying activity worksheet. The Explorer Tool allows students to quickly visualize trends in forest loss and gain, compare different countries and eco-regions, and apply the forest data to try to predict underlying causes where there is significant change in forest density. The Explorer Tool relies on open data that is used by remote sensing and GIS professionals in their work.
Fly to different parts of the world and compare data
A number of years ago, Dr. Matt Hansen and a team of researchers at the University of Maryland turned to Google Earth Engine to map high-resolution global forest cover with Earth Engine's cloud-based image processing and computing. The team mapped global forest loss and gain from 2000 to 2012 at 30-meter resolution for the entire globe. In 2013, the methods and results were published in Science Magazine and online for everyone to explore. These findings are now an important part of the website Global Forest Watch, which gives governments and decision makers free access to the data and tools required to monitor and manage their forests.

Science in the Classroom (SitC) thought this was great research to bring into the classroom and make available to anyone online. SitC packages annotated research papers with supplemental teaching materials to help pre-college and college students understand the structure and workings of scientific research. SitC and Google Earth Engine built the Global Forest Change Explorer to make Dr. Hansen’s data accessible to a younger audience.

We live in a dynamic world where the pressures of population growth increasingly impact and threaten our forests. However, as we continue to make advances in technology, we have better tools to research the health of our planet. Educators can easily flip their classrooms into science labs by combining SitC materials with Global Forest Change Explorer. With these tools, students will leave sessions with a richer understanding of environmental change, more curiosity, and a desire to actively participate in protecting our forests.
