资源简介：
Light Detection and Ranging (LIDAR) is a method of locating objects on the ground using aerial-borne equipment. It is
similar to RADAR or SONAR in that the two-way travel time of an energy beam reflected off an object is precisely measured, but
this technology uses laser light instead of radio or sound waves. This technology has proven very useful in remote sensing of the
earth. It can be used...
激光雷达（Light Detection and Ranging，简称LIDAR）是一种通过搭载于空中设备的手段来定位地面物体的技术。该方法与雷达（RADAR）或声纳（SONAR）类似，均通过精确测量能量束从物体反射后的双向传播时间来实现定位，但该技术采用的是激光光束而非无线电波或声波。激光雷达技术在地球遥感领域已被证明具有极高的实用价值。它可以被应用于...
