FAQ
Frequently Asked Questions
No. Lidar uses laser light, while radar uses radio waves. Lidar typically provides higher resolution for shorter distances.
Performance can degrade in heavy rain, fog, or snow, as the laser pulses scatter more easily than radio waves.
No. While mapping is a major application, lidar is also used in speed enforcement, forestry, archaeology, atmospheric research, and autonomous navigation.
It's pronounced LYE-dar (/'laɪ.dɑːr/), with the stress on the first syllable, rhyming with 'rider'.
