Many thanks for the suggestions.
I'd really like to use the voxel approach but am getting the following error
on running t.rast.to.rast3 to create a voxel.
I've increased the hard and soft limits for open files to 40000 on my
system, but I still am unable to convert a space time raster dataset into a
3D raster map with only 5000 raster layers (note: I have 50K daily raster
layers that I need to analyse i voxel)
$ cat /proc/sys/fs/file-max
800532
$ ulimit -Sn
400000
$ ulimit -Hn
400000
Thanks,
Richard
