$ATL24 data for Marathon, Florida, illustrating the automatic detection and processing of ICESat-2 bathymetry. The top panel shows the location of the ATL24 segment extending from Vaca Key Bight south approximately 4 km. The bottom panel shows the ATL24 bathymetry profile from the shoreline to depths of 12 m. Aqua points correspond to detected sea surface, blue to bathymetry, and white to low-confidence bathymetry. Refraction correction has been applied to all bathymetric points.$

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.
