pkgetmask1

Usage

Overview

pkgetmask creates a mask raster dataset from an input raster dataset. Values smaller than the minimum value (FC-minF[0]) or larger than the maximum value (FC-maxF[0]) will result in a FC-nodataF[0] value in the mask.

Options

FC-iF[0] filename, FC--inputF[0] filename

input image file

FC-oF[0] filename, FC--outputF[0] filename

Output mask file

FC-minF[0] value, FC--minF[0] value

Values smaller than min threshold(s) are masked as invalid. Use one threshold for each band

FC-maxF[0] value, FC--maxF[0] value

Values greater than max threshold(s) are masked as invalid. Use one threshold for each band

FC-dataF[0] value, FC--dataF[0] value

value(s) for valid pixels: between min and max

FC-nodataF[0] value, FC--nodataF[0] value

value(s) for invalid pixels: not between min and max

FC-vF[0] level, FC--verboseF[0] level

verbose

Advanced options

FC-bF[0] band, FC--bandF[0] band

band(s) used for mask

FC-pF[0] AND|OR, FC--operatorF[0] AND|OR

Operator: [AND,OR].

FC-otF[0] type, FC--otypeF[0] type

Data type for output image ({Byte / Int16 / UInt16 / UInt32 / Int32 / Float32 / Float64 / CInt16 / CInt32 / CFloat32 / CFloat64}). Empty string: inherit type from input image

FC-ofF[0] format, FC--oformatF[0] format

Output image format (see also gdal_translate(1)).

FC-coF[0] option, FC--coF[0] option

Creation option for output file. Multiple options can be specified.

FC-ctF[0] colortable, FC--ctF[0] colortable

color table (file with 5 columns: id R G B ALFA (0: transparent, 255: solid)).

Examples

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

FC
pkgetmask -i input.tif -o output.tif -min 0 -nodata 0 -data 1
      F[0]

create mask. Mask is set to 0 (default value for FC-nodataF[0]) 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 FC-dataF[0])

FC
pkgetmask -i input.tif -o output.tif -min 0 -max 10 -max 0 -max 250 -b 0 -b 1
      F[0]
