pkgetmask - program to create mask image based on values in input raster image


pkgetmask
-i input -o output [options] [advanced options]

pkgetmask creates a mask raster dataset from an input raster dataset. Values smaller than the minimum value (-min) or larger than the maximum value (-max) will result in a -nodata value in the mask.

input image file
Output mask file
Values smaller than min threshold(s) are masked as invalid. Use one threshold for each band
Values greater than max threshold(s) are masked as invalid. Use one threshold for each band
value(s) for valid pixels: between min and max
value(s) for invalid pixels: not between min and max
verbose

Advanced options

band(s) used for mask
Operator: [AND,OR].
Data type for output image ({Byte / Int16 / UInt16 / UInt32 / Int32 / Float32 / Float64 / CInt16 / CInt32 / CFloat32 / CFloat64}). Empty string: inherit type from input image
Output image format (see also gdal_translate(1)).
Creation option for output file. Multiple options can be specified.
color table (file with 5 columns: id R G B ALFA (0: transparent, 255: solid)).

create mask, setting all negative values to 0 (rest to 1)

pkgetmask -i input.tif -o output.tif -min 0 -nodata 0 -data 1

create mask. Mask is set to 0 (default value for -nodata) if either band 0 is not between 0 and 10 OR (default operator) band 1 is not between 0 and 250. Else mask is set to 1 (default value for -data)

pkgetmask -i input.tif -o output.tif -min 0 -max 10 -max 0 -max 250 -b 0 -b 1
