border - plots contour boundaries of raster file into vector file
border [-v] [-m] [-l] [-t value ] [-o output_file ]
Creates a dgt file with lines which delimit different classes in input
epp file. If -l option given, puts a label point into each closed polygon.
Default output filename is constructed from name of input file, by replacing
suffix .epp by .dgt .
Lines can be created "staircase"-like or smooth. Smoothing
is controlled by tolerance factor, which defines maximum size of line
segment, which can be changed.
- --help
- Display brief usage information
and exit successifully.
- --version
- Display version number and exit successifully.
- -%, --verbose
- Display progress indication. Useful on large files, but significantly
decreases performans on small ones.
- -m, --margins
- Controls behavouir on file
edges. By default border treats all areas outside file as offsite, but
when this option given, it assumes that all classes at the file edge are
continued outside it.
- -t --tolerance
- Defines tolerance value. Default is zero
-- no smoothing.
- -o --output-file
- Allows to specify output file name explicitly.
