Explore Learning Resources

NASA’s massive archive of Earth science data are free and open to any user for any purpose—but accessing, analyzing, visualizing, and applying these data requires a certain degree of knowledge about Earth observation data and how it is collected and optimized.

Check out our catalog of learning resources to better understand data basics, explore geographic information systems (GIS), and level up your skills in areas ranging from data in the cloud to using a representational state transfer (REST) interface.
