Point Cloud
“Every lidar point that is post- processed can have a classification 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.” … arcgis.com
