altimetric data

Altimetric data refers to measurements of the Earth's surface elevation or height, often collected using satellite technology such as radar or laser altimeters. This data helps scientists analyze changes in terrain, sea level, or ice sheets over time. By measuring how far a satellite is from the ground or ice surface, it provides precise height information, which is vital for understanding climate change, sea level rise, and geological processes. Altimetric data thus offers a detailed view of Earth's topography and its dynamic changes from a global perspective.
