Measuring the growth of a Brazilian Rainforest can be a big challenge, however, an international team of researchers uses lidar-equipped drones as low-cost data collectors to monitor the forest restoration. The researchers have developed a drone that is equipped with three-dimensional laser scanning and hyperspectral imaging systems and that is capable of producing high-resolution maps and collecting hundreds of images at different wavelengths for any given area. With the drones, larger areas of the forest can be observed more efficiently than was previously done with researchers on the ground. The unmanned aircraft also have an advantage over lidar-equipped airplanes, which are more expensive to run and more complicated to organize.
