Spaceborne LiDAR altimetry

Measures surface elevation and vegetation canopy height from photon-counting or waveform LiDAR pulses; good for forest biomass estimation, ice sheet monitoring, and terrain mapping.

Full-waveform or photon-counting systems (GEDI, ICESat-2 style) return vertical structure profiles along ground tracks. Sparse spatial sampling limits area coverage -- complementary to SAR and optical rather than a standalone mapping tool. Wikipedia: Lidar
