       pkpolygonize - program to make vector file from raster image

SYNOPSIS

       pkpolygonize -i input [-m mask] -o output [options]

DESCRIPTION

       pkpolygonize  converts a raster to a vector dataset.  All pixels in the mask band with a value other than
       zero will be considered suitable for collection as polygons.  Use the same input file as mask  to  remove
       the background polygon (recommended).

              tion as polygons.  Use input file as mask to remove background polygon!

       -o filename, --output filename
              Output vector file

       -f format, --f format
              Output OGR file format

       -b band, --band band
              band index(es) to crop (leave empty if all bands must be retained)

       -n fieldname, --name fieldname
              the field name of the output layer

       -nodata value, --nodata value
              Disgard this nodata value when creating polygons.

       -v level, --verbose level
              verbose mode if > 0
