       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).

       -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
