A LAS file is an industry-standard binary format for storing airborne lidar data. The LAS dataset allows you to examine LAS files, in their native format, quickly and easily, providing detailed statistics and area coverage of the lidar data contained in the LAS files. The LAS 3.0 standard defines which combinations of sections must exist in LAS files, and in which order. For example, the ~Version and ~Well section must exist in that order in all Ver 3.0 LAS files. As in LAS version 2.0, only one well will be described within a single file. Data is stored as one, two or three dimensional arrays.LAS and LAZ files. It's important to know a little about LAS and LAZ files, the formats geospatial LiDAR data often come in.
