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...
光探测与测距（Light Detection and Ranging，简称LIDAR）是一种利用空中装备在地面上定位物体的技术。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回来的往返时间来实现定位，但此项技术采用激光光而非无线电波或声波。该技术在地球遥感领域已被证明具有极高的实用性。它可以被用于...
