Like its Cousins radar and sonar, lidar (lightdetectionandranging), works by broadcasting electromagnetic waves towards a target and then building up a picture from the reflection.
Currently, the European Space Agency (Esa) has two lidar (lightdetectionandranging) missions of its own in preparation.
目前,欧洲空间局(ESA)自身有两个激光雷达(光探测和测距)任务正在准备中。

Forest parameters, especially forest height, can be inverted from LightDetectionAnd was processed task, Ranging (LiDAR) dataset, which should promote the applications of LiDAR in forestry.
