Grouping LIDAR dataset Based on the Classification Field
Some LAS formats have a predefined classification scheme that defines the type of object that has reflected the laser beam. Based on the classification scheme, the LIDAR points are classified into a number of categories such as bare earth, buildings, top of the forest canopy, and water etc. These categories or classes are denoted by a classification ID. The different classes are defined using numeric integer codes in the LAS files.
When grouping by LIDAR classification field, you can provide both complete classification field or just the index. In case you provide the index number, then MapInfo Pro Advanced converts them into the complete string.
