Free, MIT-licensed Python library and documentation for applying AI to satellite and geospatial data, with tutorials, notebooks, a QGIS plugin and video walkthroughs.

Why I recommend it: A free, well-documented open-source project — a good portfolio path if you want to work in mapping, climate or remote sensing.
An open-source, browser-based "spy satellite simulator" that plots real satellites, planes, vessels and public cameras on a photorealistic 3D globe, and answers questions about the planet in plain language.
Why I recommend it: A striking free build to study or fork if you want a portfolio project that people actually stop and look at.
