program to create mask image based on values in input raster image
Usage: pkgetmask -i input -o output
Options: [-min value]* [-max value]* [-data value]* [-nodata value]*
Advanced options: [-b band]* [–operator AND|OR] [-ot type] [-of format] [-co option]* [-ct table]
The utility 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.
-short or --long options (both --long=value and --long value are supported)-h shows basic options only, long option --help shows all options | short | long | type | default | description |
|---|---|---|---|---|
| i | input | std::string | Input image file | |
| o | output | std::string | Output mask file | |
| min | min | double | Values smaller than min threshold(s) are masked as invalid. Use one threshold for each band | |
| max | max | double | Values greater than max threshold(s) are masked as invalid. Use one threshold for each band | |
| data | data | unsigned short | 1 | value(s) for valid pixels: between min and max |
| nodata | nodata | unsigned short | 0 | value(s) for invalid pixels: not between min and max |
| b | band | short | 0 | band(s) used for mask |
| p | operator | std::string | OR | Operator: [AND,OR]. |
| ot | otype | std::string | Byte | Data type for output image ({Byte/Int16/UInt16/UInt32/Int32/Float32/Float64/CInt16/CInt32/CFloat32/CFloat64}). Empty string: inherit type from input image |
| of | oformat | std::string | GTiff | Output image format (see also gdal_translate). |
| co | co | std::string | Creation option for output file. Multiple options can be specified. | |
| ct | ct | std::string | color table (file with 5 columns: id R G B ALFA (0: transparent, 255: solid) |
