OS X El Capitan, GRASS GIS 7.0.1
I have a location with about 530 read-only mapsets with each about 2600 raster maps (plus PERMANENT and one link to a read-write mapset), overall 1.255.481 raster maps and about 200 GB.
What is the best way of storing these in a space efficient way and tohave them accessible read-only?
I have them at the moment in a grass database and thought of putting these into a squashfs which shouldwork (tried with a subset and it was nice - mounting fast, space efficient), but after two days of compressing (and only having compressed30% - slow speed presumably due to huge number of files) I gave up.
I would like to avoid having to install postgresql as I tried it before(several years ago) and given up due to it's complexity.
I will analyse the maps in R, so any storage backend which I can useFrom R and GRASS would be OK.
Any suggestions?
