Description

see http://gdal.org/structGDALWarpOptions.html#0ed77f9917bb96c7a9aabd73d4d06e08

"OPTIMIZE_SIZE: This defaults to FALSE, but may be set to TRUE when outputing typically to a compressed dataset (GeoTIFF with COMPRESSED creation option set for example) for achieving a smaller file size. This is achieved by writing at once data aligned on full blocks of the target dataset, which avoids partial writes of compressed blocks and lost space when they are rewritten at the end of the file. However sticking to target block size may cause major processing slowdown for some particular reprojections."
