Today’s 3D maps drawn by lidar technology not only have more detailed details, but also draw faster. The green laser pointer radar can be used to measure in days or even hours, while traditional methods take weeks or even years Time to survey. Mapping systems using lidar technology are not only used for exploration, they can also provide far-reaching benefits to various industries such as urban planning, construction, environmental work, disaster relief, and drone delivery.
For example, to address climate change applications, lidar mapping can help scientists understand how quickly forests are decreasing, how fast oceans are rising, how quickly ice caps are shrinking, and more. After suffering from natural disasters such as tornadoes, hurricanes, and earthquakes, scientists can use lidar to map the affected area and identify areas of vulnerability, and locate dumped trees and electrical towers without putting rescuers at risk.
If Typhoon Sandy invaded New York in 2012, relief workers installed green laser pointers on trains and entered the New York subway tunnel that was flooded during the typhoon to detect structural damage. Like early explorers who used maps to explore the unknown world, humans are now discovering lost civilizations and planning future cities in a more advanced way. Lidar, like the third eye of humans, has already played a huge role in map applications.
