How to Get Started with Free Satellite Imagery: Sentinel, Landsat, CBERS, and More | HackerNoon
Briefly

Sentinel-2, part of Copernicus, excels in multispectral imaging. It's my preferred choice for its optimal balance of spatial, temporal, and spectral resolutions.
Landsat has provided continuous multispectral imaging since the 1970s, with Landsat-9 being its latest mission, supporting diverse applications in environmental analysis.
When choosing a satellite program, consider specific project needs. Some focus on niche regions while others offer broader global perspectives.
Brazil's satellite programs, CBERS and Amazonia, introduce valuable alternatives, particularly for users interested in national data, enhancing global satellite imaging options.
