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.
