Nikos:
I am building a docker image, based on trunk, for which I need to ensure that ZSTD is the default compressor. What is the way to pre-set this at the configuration step, before compiling, so as to avoid to take care about it later on by setting GRASS_COMPRESSOR?
Markus M:
ZSTD is already the default compressor if available, no further settings needed.
Great! However, descriptions of compressors in the raster indroduction for trunk [0], are maybe confusing. ``` ZLIB ZLIB's deflate is the default compression method for all raster maps. ``` and ``` ZSTD ... ZSTD is the recommended default compression method. ``` The same piece of text is used for `r.compress` [1]. [0] https://grass.osgeo.org/grass75/manuals/rasterintro.html [1] https://grass.osgeo.org/grass75/manuals/r.compress.html I realised this before commenting in #3499. Yet, I thought "default" is ZLIB, and "recommended default" (like: "dear user, it's best if you set ZSTD as the default") is ZSTD. Nikos
