Usage: $PROG [-sldobj] input-basename calc-expr
54+
55+
optional:
56+
-s = pixel resolution of cubed data, defaults to 10
57+
-l = input-layer: band number in case of multi-band input rasters,
58+
defaults to 1
59+
-d = input directory: the datacube directory
60+
defaults to current directory
61+
'datacube-definition.prj' needs to exist in there
62+
-o = output directory: the directory where you want to store the cubes
63+
defaults to current directory
64+
-b = basename of output file (without extension)
65+
defaults to the basename of the input-file,
66+
appended by '_procmask'
67+
-j = number of jobs, defaults to 'as many as possible'
68+
69+
Positional arguments:
70+
- input-basename: basename of input data
71+
- calc-expr: Calculation in gdalnumeric syntax, e.g. 'A>2500'"
72+
The input variable is 'A'
