According to the plan, the green laser pointer radar system will be placed on a truck, and the car will collect data on suspended particulates in various areas in Paris, so that scientists can understand what the suspended particulates are on the road, and on the stairs, in the house What are the particulate matter. Scientists will also analyze the changes of particulate matter according to different periods, so as to provide a reference for air pollution treatment decisions. The advantage of this is that it can hardly damage the scene.
In the past, when people analyzed particulate matter, they often interfered with the characteristics of the scene, so the information obtained was less accurate. New York uses lidar to gather information to make a three-dimensional map. The New York City Office of Long-Term Planning and Sustainable Development chose to use lidar to gather information to draw a three-dimensional map of New York. The current flood floor map was produced by the Federal Emergency Management Agency in the 1980s based on aerial images and ground surveys.
As cities become more crowded, this map is no longer accurate enough and needs to be updated. According to local government officials, the information collected by these green laser pointers radar technology can also be used to solve other problems, such as whether there are still some wetlands in the city, how many square meters of roofs, and how many beveled roofs. Roof statistics can be used to build online solar maps, assist in assessing the city’s solar capacity, and even allow New Yorkers to check whether the buildings they live and work in are suitable for solar panels.
