How to convert Tiff to GeoTIFF
How to remove the nodata values from a GeoTIFF?
I find many instructions on how to add the values, but none on how to remove them. => There isn't a direct way of accomplishing this. You could extract a work.vrt file, then manually edit it and remove the line(s) with the NoDataValue tags. Then convert back to geotiff:
% gdal_translate -of VRT your.tif work.vrt % gdal_translate work.vrt fixed_your.tif
"cloud optimized" GeoTIFF

creation: GeoTIFF to "cloud optimized GeoTIFF
(According to above talk, 00:11:14)

-co COMPRESS=DEFLATE instead of
-co COMPRESS=LZW. According to https://trac.osgeo.org/gdal/wiki/CloudOptimizedGeoTIFF#Unspecifiedpoints, either can be used.
