We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition. Read about the Web Unification Project

Topography Data Access and Tools

NASA data detail topography across the land surface, ocean, cryosphere, terrestrial hydrosphere and within the context of climate change. Our datasets and tools help researchers translate these interconnected data points into actionable knowledge.

Topography Featured Observation Method: ICESat-2

NASA's Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) allows scientists to measure the elevation of ice sheets, glaciers, sea ice, and land across Earth's temperate and tropical regions, as well as take stock of the vegetation in forests worldwide. ICESat-2 carries the Advanced Topographic Laser Altimeter System (ATLAS), which sends 10,000 pulses of laser light to the ground per second and then measures how long it takes them be reflected back by the surface to determine the area's elevation. Learn more about ICESat-2/ATLAS near real-time data provided by NASA's Land, Atmosphere Near real-time Capability for Earth observation (LANCE). ICESat-2 carries the Advanced Topographic Laser Altimeter System (ATLAS), which sends pulses of laser light to the ground, collects the returning photons in a telescope, and records the photon travel time.
