-------- Messaggio Inoltrato -------- Oggetto: GDAL COG+LERC compression Data: Thu, 17 Sep 2020 19:55:38 +0200 Mittente: Antonio Valentino <[email protected]> A: Sebastiaan Couwenberg <[email protected]> Dear Sebastiaan, today I tried to made some tests to generate Cloud Optimized Geotiff (COG) files with LERC compression. I realized that this is not possible in debian because, if I understand correctly, we build GDAL using system libtiff while the LERC compressor, according to [1], need the internal libtiff. Can you please confirm that my understanding is correct? The strange thing, to me, is that the same limitation also applies to the the ZSTD compressor [1], but in this case I'm perfectly able to generate COG files with ZSTD compression in debian. I gave a look to how we generate the package an haven't found no specific configuration/patch regarding this aspects, so I'm wondering if I'm missing something or if there is a small bug in the GDAL documentation of the COG driver [1]. Do you have comments/hints? [1] https://gdal.org/drivers/raster/cog.html#raster-cog -- Antonio Valentino
