     26* size of tile: 256 or 512 pixels are typical however
     27* compression methods allowed. typically, no compression, DEFLATE or LZW can be used for lossless, or JPEG for lossy. (note that DEFLATE while more efficient can LZW can cause compatibility issues with some software packages)

    2429== How to generate it with GDAL ==
    2530
    2631Given an input dataset in.tif with already generated internal or external overviews, a cloud optimized GeoTIFF can be generated with:
    2732
    28 gdal_translate in.tif out.tif -co TILED=YES -co COPY_SRC_OVERVIEWS=YES -co COMPRESS=DEFLATE
     33gdal_translate in.tif out.tif -co TILED=YES -co COPY_SRC_OVERVIEWS=YES -co COMPRESS=LZW
    2934
    3035This will result in a images with tiles of dimension 256x256 pixel for main resolution, and 128x128 tiles for overviews.
