demzip

Compresses and uncompresses raster data from ASC, BIL, TIF, IMG 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.
