NASA | Intro to LIDAR - 3D Version

The video tutorial explains 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 accurately and create 3D models of planetary terrains. LIDAR's versatility extends to studying Earth's forests, ice caps, and atmospheres, as well as those of other planets, without the need for physical exploration.

What challenges do scientists face when measuring heights on other planets compared to Earth?

Explain how LIDAR technology works in measuring distances to the landscape.

How do scientists use LIDAR to create a 3D model of a planet's terrain?

What are some applications of LIDAR technology beyond measuring mountain heights?

Discuss the significance of using LIDAR for studying Earth's atmosphere and other planets.
