What is one essential feature of LIDAR technology in contrast to RADAR?

One essential feature of LIDAR technology is that it employs laser technology. LIDAR, which stands for Light Detection and Ranging, utilizes laser beams to measure distances and gather data about the earth's surface and other objects. The laser light emitted by LIDAR systems can provide highly accurate distance measurements and is effective in creating detailed 3D models of the scanned area.

In contrast, RADAR (Radio Detection and Ranging) utilizes radio waves rather than laser light. This fundamental difference in the type of waves used allows LIDAR to achieve higher resolution and precision in its measurements, particularly for applications requiring fine detail, such as mapping and environmental monitoring. The ability to emit and measure reflected laser light is what sets LIDAR apart and makes it suitable for specific applications that benefit from this level of precision and accuracy.
