OVER DEZE AFLEVERING
Machine learning scientist Gracie Ermi joins Charna Parkey to explore how AI and open-source satellite data are changing the way we understand land use, climate impact, and environmental risk. At Impact Observatory, she helps create high-resolution, publicly available maps used by educators, researchers, and global organizations alike. A conversation about the technical challenges behind these tools, what open access really looks like in practice, and the role AI plays in making environmental data faster and more useful.

Charna Parkey
“One of the most exciting things about where AI is headed is that we’re finally expanding its use beyond language. Gracie’s work is a prime example of how machine learning can interpret physical space, detect environmental change, and deliver insights that matter. It’s a reminder that AI isn't just a chatbot—it’s a tool to see, sense, and protect the planet.”

“The biggest innovation we need right now isn’t necessarily a new AI model. It’s better, cheaper satellite imagery—especially higher-resolution data that’s still open access. Right now, we’re working mostly with Sentinel imagery, which has a 10-meter resolution. That’s great for a lot of things, but it limits what you can detect. Individual buildings, small changes—they get lost at that scale. If higher-res data became more affordable or openly available, it would change everything.”
