osmcoastline_filter - filter coastline data from OpenStreetMap file
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
If you are playing around or want to run osmcoastline
several times with
different parameters, run osmcoastline_filter

output as the input for osmcoastline
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
programs work fine with it.
