NASA’s CASALS Instrument Bridges Gaps in 3D Maps of Earth’s Surface

NASA reports: NASA’s CASALS instrument will blend machine learning with an ultra-compact lidar instrument to adaptively ‘sweep’ large swaths of Earth’s surface.

From orbit, today’s space-based laser instruments measure Earth’s forests and terrain one narrow line at a time. Between those lines are enormous gaps that include millions of acres of land scientists never directly measure.

This science story centres on the United States. Names and organisations mentioned in the coverage include Maps of Earth’s Surface, NASA’s CASALS Instrument Bridges and Earth.
