Hi, Even.
Using both options "-optim raster" and "-optim vector" results in the same
size files. This is expected, since, as follows from the option description, it
only affects the rasterization algorithm.

so simple to update already compressed data in place. Have you tried what

Hello.
I’m using gdal_rasterize to remove some data from DEM (Int16) and hillshade
(Byte) rasters with shape-file, like this:
gdal_rasterize -burn -32768 shape.shp dem.tif and gdal_rasterize -burn 0
shape.shp hillshade.tif
Both DEM and hillshade GTiffs created with -co COMPRESS=LZW -co TILED=Y
