SYNOPSIS
pkgetmask -i input -o output [options] [advanced options]DESCRIPTION
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.OPTIONS
- -i filename, --input filename
- input image file
- -o filename, --output filename
- Output mask file
- -min value, --min value
- Values smaller than min threshold(s) are masked as invalid. Use one threshold for each band
- -max value, --max value
- Values greater than max threshold(s) are masked as invalid. Use one threshold for each band
- -data value, --data value
- value(s) for valid pixels: between min and max
- -nodata value, --nodata value
- value(s) for invalid pixels: not between min and max
- -v level, --verbose level
- verbose
Advanced options
- -b band, --band band
- band(s) used for mask
- -p AND|OR, --operator AND|OR
- Operator: [AND,OR].
- -ot type, --otype type
- Data type for output image ({Byte / Int16 / UInt16 / UInt32 / Int32 / Float32 / Float64 / CInt16 / CInt32 / CFloat32 / CFloat64}). Empty string: inherit type from input image
- -of format, --oformat format
- Output image format (see also gdal_translate(1)).
- -co option, --co option
- Creation option for output file. Multiple options can be specified.
- -ct colortable, --ct colortable
- color table (file with 5 columns: id R G B ALFA (0: transparent, 255: solid)).
EXAMPLE
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
