LAZ is a lossless compression of the LAS format. The latest LAS specification is the LAS 1.4. laspy supports LAS files from Version 1.2 to 1.4. LAS files are organized in 3 main parts: Header VLRs Point Records Header ¶

I know how to filter the appropriate returns for either the DEM or the DSM, but I am unsure what the sampling size should be (along with Sampling type: Cellsize). From the metadata I've been provided, the lidar (LAS) files have a horizontal resolution of 0.31m. However, the average point spacing is about 1.3 (for each LAS file, there are only two).

Usage. This tool can convert lidar data stored in the LAS format or the ZLAS and LAZ compressions. The output files can also be created in a different .las file version and point record format that support a larger set of classification codes and flags.
