Web5 de nov. de 2024 · A laser is a device that converts pumping energy (light, electrical, thermal, chemical, etc.) into coherent, monochromatic, polarized and narrowly directed radiation flow energy. Laser types: Existing types of lasers can be classified according to several criteria. First of all, by the aggregate state of the active medium. WebEvery lidar point can have a classification assigned to it that defines the type of object that has reflected the laser pulse. Lidar points can be classified into a number of categories including bare earth or ground, top of canopy, and water. The different classes are defined using numeric integer codes in the LAS files.
