NAME
       osmcoastline_filter - filter coastline data from OpenStreetMap file


SYNOPSIS
       osmcoastline_filter --output=OUTPUT_FILE INPUT-FILE

       osmcoastline_filter --help


DESCRIPTION
       osmcoastline_filter  is  used to filter all nodes and ways needed for building the coastlines from an OSM
       planet.  The data is written to the output file in PBF format.

       This output file will be a lot smaller (less than 1%) than the original  planet  file,  but  it  contains
       everything needed to assemble the coastline and land or water polygons.

       If  you  are  playing  around  or  want  to run osmcoastline several times with different parameters, run
       osmcoastline_filter once first and use its output as the input for osmcoastline.

       osmcoastline_filter can read any file format supported by libosmium (in particular this is PBF, XML,  and
       OPL  files),  but write only PBF files.  PBF files are much smaller and faster to read and write than XML
       files.  The output file will first contain all ways tagged “natural=coastline”, then all nodes  used  for
       those  ways (and all nodes tagged “natural=coastline”).  Having the ways first and the nodes later in the
       file is unusual for OSM files, but the osmcoastline and osmcoastline_ways programs work fine with it.


OPTIONS
       -f, --format
              Set output format options (default: pbf).

       -h, --help
              Display usage information and exit.

       -o, --output=OSMFILE
              Where to write output (default: none).

       -v, --verbose
              Enable verbose output.

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


EXAMPLES
       Run it as follows:

              osmcoastline_filter -o coastline-data.osm.pbf planet.osm.pbf
