****************************************************************

demzip:

Compresses and uncompresses raster data from ASC, BIL, and TIF
format to the compressed RasterLAZ format. The expected inputs
are rasters containing elevation data such as DTM, DSM, or CHM
rasters, or GEOID difference grids, or forestry metrics. These
values will be compressed into the z coordinate of RasterLAZ.

For updates check the website or join the LAStools mailing list.
