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. | ||
