NASA | Intro to LIDAR - 2D Version

The video discusses the challenges of measuring mountain heights on other planets compared to Earth. It introduces LIDAR technology, which uses laser pulses from satellites to measure distances and create 3D models of terrain. LIDAR is versatile, used for mapping landscapes, studying Earth's forests, ice caps, and atmospheres, and analyzing planetary features without physical exploration.

Describe the process by which scientists create a 3D model of a planet's terrain using LIDAR.

How does LIDAR contribute to understanding the composition and structure of atmospheres?
