NAME

       osmcoastline_segments - analyze coastline changes from segment files

SYNOPSIS

       osmcoastline_segments [OPTIONS] SEGMENT-FILE1 SEGMENT-FILE2

DESCRIPTION

       The  osmcoastline  program  can  write out all segments of the coastline into a file (when
       started with the -S, --write-segments=FILE option).  This program can be used  to  compare
       two  of  those segment files in various ways to detect coastline changes between different
       runs of the osmcoastline program.

OPTIONS

       -h, --help
              Display usage information.

       -d, --dump
              Dump segment list to stdout in plain text format.

       -g, --geom=FILENAME
              Write segments to geometry file or database using OGR.

       -f, --format=FORMAT
              OGR format for writing out geometries.

       -V, --version
              Display program version and license information.

DIAGNOSTICS

       osmcoastline_segments exits with exit code

       0      if the segment files are the same 1
       if the segment files are different 3
       if there was a fatal error when running the program 4
       if there was a problem with the command line arguments.

EXAMPLES

       Just return 0 or 1 depending on whether the segments are the same in both files:

              osmcoastline_segments old.segments new.segments

       Dump the list of removed and added segments to stdout:

              osmcoastline_segments --dump old.segments new.segments

       Create a shapefile with the differences:

              osmcoastline_segments --geom=diff.shp old.segments new.segments
