NAME
border - plots contour boundaries of raster file into vector fileSYNOPSIS
border [-v] [-m] [-l] [-t value ] [-o output_file ]DESCRIPTION
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.
OPTIONS
- --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.
